After Core 2 Duo, you can win the high 🙂 Ale, AMD has a discounted price, and the result is a choice of ruptures.

After reading on the forums, in magazines, that drunk people, having decided to move to a chotiryaderny processor without special financial expenses. Vibir fell on the Phenom II X4, the youngest model 810. At the same time, the ASRock A770DE motherboard was attached to it. You need an inexpensive ATX board for 3 pci and 2 pci-express. The choice was not special 🙂

Test configuration

• CPU AMD Phenom X4 810 (2.6 GHz, Quad-core, 4Mb L3)
• MB Asrock A770DE
• Cooler BOX is so small 🙂
• RAM 2x2Gb TakeMS DDR2-800 CL5
• HDD WD6400AAKS 640Gb 16Mb 7200rpm
• video ASUS EN7300GT Silent 256Mb
• BP CoolerMaster 460W 460-PCAP-A3
• frame 4U 4710 + 120mm indoor fan @ 5V
• OS Windows XP SP3 32bit

Rozgin

Having read about those, how to marry Phenom II well, turn on the standard pressure, virishiv overturn the thesis. Also, approximately estimate the energy saving of the processor. Unfortunately, I don’t know specifically the thermal imaging of the 810th processor in the least, who is recognized, I correct, thermal imaging is acceptable to that TDP=95W.

Rozgin was carried out for such improvements:

• Cool'n'Quiet - OFF
• Multiplier NB and HT - 8
• Voltage NB - 1.2 V
• Bus frequency - 270 MHz
• Memory frequency - 448 MHz (892 DDR2) (1.66 multiplier)

The processor multiplier dropped to 10, so I marveled at how many processors I took, starting at the default frequency on the 270 MHz bus. The frequency was changed in increments of 0.5 * 270, to 135 MHz.

At the standard voltage (1.325V), the processor peaked at 3105 MHz. Sparsely, deyakі praised little more than 3.6 GHz. When transferring thermal imaging (PT) = 113 W. І etc. according to the table

* - redeemed on the basis of TDP

boxed cooler

Honestly, apparently, I didn’t want to work the rudeness of my computer, so the increase in frequency seemed to be modest. In addition, a boxed cooler can hardly handle a 1.475 processor at maximum RPM (and it can be noisy at cfu).

To turn on the default cooler runs more than 1800 revolutions per whilin when video is encoded - the noise becomes less. Tobto. If you like quiet computers, I recommend either buying a normal cooler or undervolting.

Undervolting

By analogy with overclocking, undervolting is a phenomenon, in which the frequency and productivity of the processor are often kept the same, or the voltage is changed. As a result, we need a colder processor, which works at the same frequency, with the same productivity. For the price of Intel and AMD processors, there is a lot of money - Intel Q8200S, Q9400S, Q9550S, as well as AMD Phenom 705e, 905e. Let's build such a processor with our own hands;

My processor was able to pass S&M tests at a standard frequency of 2.6 GHz at a voltage of 1.15, and thermal output is expected to be close to 72 watts. Without knowing it, AMD set the frequency of 2.5 GHz to its 65W processor.

As a result, I didn't manage to buy a normal cooler - at the box temperature when the video was coding more than 51 degrees, it didn't rise at 1500 rpm for the whilin - it's quiet and comfortable.

Cool'n'Quiet and productivity

Seemingly, I had a chance to turn on CnQ through a drop in productivity on Windows. Whether there is flash, a couple of browsers and 800 MHz are no longer working, and the XP driver seems to be clumsy. What's the reason? Even in Windows, I still can't change it :) I've looked at the productivity of phenomena at a lower frequency.

For which the frequency was reduced by a multiplier. Frequencies NB, HT and memory were left with the standard ones.

Results in Everest 5.02:

The results speak for themselves - back in an hour Pentium 100 :).

The performance of the memory controller also depends heavily on the frequency. So I've decided to turn on CnQ for the time being, I would like to before switching to Windows 7.

Good afternoon, doby comrade overclockers and future overclockers, and also just readers.

In this article, I will write how to recognize the AMD Phenom II x4965BE processor. I'm not going to write down the scribbling as a single, non-repeating and non-reprimanding instruction before dispersal. I tried to write її more simple and sensible mine. All vysnovki and recommendations here are turned on my special certificate that warning, as well as the numerous FAQ "ah overclocker forums, read and analyze various articles from the dispersal, well, of course, exchange the information when spoofing on various overclocker forums.

In these articles, you will not hear everyday philosophical thoughts about the nature of dispersal, about yoga, and that task too thinly.

Here I’ll be idle, with my greatest help, I’ll share my opinion on dispersal and give a number of recommendations and joys.

I’ll tell you ahead of time that the article is recognized for computer-literate people, computer scientists, that more or less understand slang, that they can independently develop / choose from components system block, what processors want to sort out and sort out by their names, know their main characteristics, what they can climb and dig into the bios, ale tim no less- do not know (badly know) or only pochatkіvtsіv razbiratsya at the dispersal.

Already informed people, nothing new can be known from the statutes - if only the little ones can "fear" the memory, then show me the pardons they know.

Now about pardons. Oskіlki I am a person, then I can pardon. The more you remember them, the better. Write here - and I will correct it. With your help, this article can become more short, more informative. If you care that I'm not enough visvitl deyaki nutritious - so write.

In fact, I am guilty of writing this instruction a long time ago - two or three years ago. Three quieter reasons were not given. The main reason, of course, is a mighty line. Tim more, like earlier, є people, yakі tsіkavlyatsya by overclocking the processors with a hair dryer2.

Yak and lie down be-yakіy statti s dispersal - discamer :

I’ll guess what you’re dieting for your fear of that risk. I am for your manipulations (after reading mine and not mine the same article) with your and not your computer and for coming after them, I don’t see any negative and positive consequences.

The reason for the creation of these stats is to change the number of newcomers to overclocking processors, specifically - AMD Phenom II (hereinafter - just a phenom2). You should also protect those that I will guess my young self, if I don’t know anything and don’t know anything. I didn’t suspect about the basis of such guides.

Trochy thoughts [ I recommend skipping this part, because you don’t carry anything brown].

[Before the speech, food for all - can you see a part of the varto? Maybe she won't be needed by the statute?

Having started earlier in 2008, the rock is the first processor Intel Pentium Dual Core E 2160 , Independently - without reading relevant materials and knowing something - it’s amazing to learn by yourself, by stepping through the bus up to ~ 2400 MHz - even though I didn’t know what the voltage on the core needed to be increased. But it’s all the same - the motherboard bula vіdvertim UG іz wretched bios, as it allowed only the bus to change, the voltage was blocked. Let me buy a good motherboard for MSI(I don’t remember the names for the old age) and nachebto (how it was given to me) Asus Triton 75 which really turned out to be bullshit and ripped out the big voltages up to 3300 MHz. Let's buy an expensive one from this hour Zalman CNPS 9700 A LED. At that hour, I found out and not guessing that the mosfeti, with increased voltage, might heat up the power, that I didn’t know anything about those, how the processor is eating, what is the temperature between and throttling, what is the FAK and our partner At the next hour, everything was very vague.

Obviously, even though I didn’t read everyday articles and forums, there was no Internet. It was possible to touch everything on your own with a clear path - rightly, then rightly so. It's just amazing that I didn't burn anything. The reason for this, perhaps, was those that I uninformedly zastosovuvav method of full dispersal. I'm nasty not maw pro stability testing processor and memory. I didn’t know about those who cracked the video card :-)

It is important to remember to break up the operational memory - even if the FSB is alone, you yourself will understand. Changed the platform to AMD via rіk, adding an overclocker (as it was done for me) memory kit Kingston HyperX 1066 MHz, matir gigabyte GA-MA790X-UD3P(to the point - a miracle motherboard), well, a processor Phenom II x 3 710 2600 MHz. Specially for overclocking. Just like that, I already started to read (less to read and more than an hour) site overclockers.ru

Good luck, mothers changing to gigabyte GA-890XA-UD3- also a miracle overclocker's mother. I think at once - why did I change the matir - the pivnіchny place in both vipads is the same 790X, pivdenny SB 750 changing to SB 850 . Adzhe actually - there was no retail.

After sorting through three processors, stupidly buying and selling for what they want (our place doesn’t have a store, I would practice such a miracle feature like "moneyback") Phenom II x 3 710 , one processor Phenom II x 3 720ВЄ- and all for the sake of otrimanny zapovіtnyh kak me todі it was given 4 GHz. It didn't. As soon as I understand, the first revisions of Phenom II were the fault. Usі stink stably razlachuvalis to povnotsіnnih Phenom II x 4 . Prote, the maximum frequency of the stele of the stink is different - from 3400 to 3700 MHz. Dancing with a tambourine is like a bios, the tension is thin. too thin, in that number the regime had several cores turned on, they did not help. As a result, having bought a 6-core new and troch already having thrown off the prices Phenom II x 6 1090 BE. The axis of the wines was immediately without a problem, taking a stable 4000 MHz at a pleasant voltage. At 4100-4200 MHz, Windows came in, but there was no stability. Before speech, for whom I changed the cooler to "folk" and even more popular Scythe Mugen 2 Rev . B(Such a todish vote on the overclockers.ru forum - "The best bashtovy cooler").

Otrimavshi zapovitni 4 GHz on the phenom2, I troch lowered my interest to overclocking. І I thought it would be wrong to switch to a fresh current socket 1155 - І, having sold a hairdryer2, having added a processor Intel Core i 5 2500 K. At that time, I made friends with one store and sorted through three such processors and knew "the very same percent", which gave a stable 5 GHz on the floor.

For whom I have installed a top motherboard for whom MSI P 67 A - GD 80 (only through pіvroku pіznіshe viyshov dear Big Bang-Marshal). Ale potim pobachiv miraculous fee - ASRock P 67 Extreme 6 ( B 3) - once I took її - only through 10 internal sata-ports (I sometimes had 10 pieces of 3.5 "hardware I got it). I know there were miracle buttons clear _ cmos , power , reset(And I sold the MSI GD80). So at the same store, I closed and took the same best cooler in the world =) thermal right Silver Arrow- which is the most contagious, as if hanging on a new couple or three TR TY -150 . Oscilki are stable at 5 GHz (with the recommendations of 1.40) were already rooted, I set the processor to "economy" 4200 MHz at 1.32 V. What is wonderful Through the pіvroku vіn stopped trimming 5 GHz, regardless of the chaklunstva - digging into the bios. Well, that harazd - boo, I thought and happily forgot about it.

Let's go, let's go, I'll take it for tests Noctua NH - D 14 , TR Archon, Well i Zalman CNPS 10 X Flex, "for reference", so bi motion. I wrote Three Kings...

Goodbye Archontiv, At once, I have five. Having posited a couple of pieces at the store - at once it became sim. I wrote the Order of the Seven Archons.

And then a handful of people wrote to me that it would be better to discuss the topic of overclocking processors with a hair dryer2. Axis about tse y timetsya.

Otzhe - let's turn to our sheep phenomena.

Otzhe, you have a processor phenom2x4965BE. Guess what the letters BE mean Black Edition, to unlock the bіk zbіlshennya multipliers, the head rank of CPU and CPU/NB.

Also, you can have a good processor cooler and a good motherboard. Tse necessary mind for safe and stable dispersal. It is especially important when there is a great need for a processor for a long time.

IMHO, which cooler is suitable for overclocking, can be determined in two ways:

It is important to determine whether the motherboard can go before overclocking in a chainikov's way offhand - for the presence / absence of radiators on lanceugs livelihood, which are also called mosfets ( field transistors, poloviks). Also, the applicability of the motherboard to overclocking can be directly determined per number of phases eating processor. The more the better.

Also, a necessary power supply unit due to some overworld sweating - the chips after overclocking the processor start to save more energy. Report about tse I hung. I nonchalantly recommend її to read, to get rid of the "zayvih" food.

Break the percent, for an idea, it's easy. We may have a Phenom2 x4 965BE processor, which has a nominal multiplier of 17 and, also, a nominal clock frequency of 17 x 200 MHz = 3400 MHz. The nominal voltage of the processor for its own is 1.40 U.

For overclocking the processor, there are two ways: by bus and by multiplier. More about them below.

1. Rozgin by tire. How to work?

At par, the bus frequency is 200 MHz. More than that, we can increase the sub-bag frequency of the processor. For example, from 200 MHz to 230 MHz. Then, with a nominal multiplier of practice, which is more than 17, we can have a sub-bag frequency of 17 x 230 MHz = 3910 MHz. I took the increment 3910-3400 = 510 MHz.

ale, It's just that the processor at its nominal voltage (equal to 1.40 V) does not take the frequency of 3910 MHz - it's stupid not to get the processor alive - to work at this frequency. To be brought trochs increase the pressure. I took a frequency of 3910 MHz less yak butt, shards for the skin processor stele dispersal individual, just like that voltage, at a certain frequency.

Vіzmemo three same processor -, for example, the first one is easy to take 4 GHz, with a voltage of 1.46 U.

The other processor, also acceptable, runs at 4 GHz or less with strong "stoking" - voltage, which is more expensive 1.50 V.

And the third processor, let's say, take a maximum of 1.38 GHz - even though we increased the voltage.

Visnovok: Rozgin is a whole lottery. The overclocking potential of the skin processor is its own.

Before overclocking, through the bios, turn off all power-saving functions. Functions of bios work on automatic, independently setting the voltage of the processor's life and frequency. Tsіl tsikh energy saving technologies- Save electricity in the computer downtime, by changing the multiplier to 4 (4 x 200 MHz = 800 MHz), so it is applied to the percentage of voltage, therefore, lowering the overall energy saving of the system.

There are not the same fluctuations, if the processor has been processed incorrectly through the functions. To that їkh slid vimknut.

Bios stinks under names Cool " n " quiet, as well as C 1 E- Їх слід put in position.

Photo energo-enabled

1.1. Bus overclocking technique

1. Let's go to bios. We drop everything on the default keys F2 or F5 or F8 or F9 and so on. - The skin matplati has its own way. Take care and apparently.

2. Let's go to bios.

We marveled at that part, yak povіdaє for rozgіn. In my mind, everything looks like this:

Remember (novices can also write down on paper) q numbers:

Current CPU Speed- The current frequency of the processor.

Target CPU Speed- The frequency of the processor, which is set at the given moment.

Current Memory Frequency- flow frequency operational memory.

Current NB Frequency- streaming frequency of the memory controller loaded into the processor and the memory cache of the third level (L3), also called CPU / NB. The very frequency is violating, with some kind of speed, the processor and operative memory are "removed". The frequency of the CPU/NB can also be adjusted - and the increase will be remembered, lower if the processor itself is overclocked in a similar way.

Current HT Link Speed- streaming frequency of the Hyper Transport bus (further - HT), as the back end of the processor. Although the real frequencies of the CPU / NB and HT are reduced, the effective speed (to be more precise - the throughput capacity) of the HT bus is large (5.2 billion orders per second), so it is not needed.

Until then, the architecture is such that the HT frequency cannot be higher than the CPU/NB frequency. Therefore, the next step is to break up the CPU / NB, and the HT frequency is depleted at nominal - 2000 MHz.

3. Now fix the necessary parameters:

AI Overclock Tuner- Z is set to , so that the automatic opening is switched to manual mode. Tse allows us to vibrate with the frequency of the tire.

CPU Ratio- the multiplier of practice is translated z, for the additional keys "plus" and "minus". Tobto fix / close the nominal multiplier - so that the bios "vipadkovo" does not automatically change it.

CPU Bus Frequency- the bus is set to nominal - 200 MHz.

PCI - E Frequency- PCI-E bus is fixed at nominal 100 MHz.

Memory Frequency- The memory frequency is fixed on the regular 1333 MHz.

CPU / NB Frequency- The frequency is fixed at regular 2000 MHz.

HT Link Speed- also fixed on regular 2000 MHz.

CPU Spread Spectrum- set - turn on the feature, so that the EMI of the computer is lowered, which gives stability during overclocking. Why-we read.

PCI - E Spread Spectrum- tezh we put in - purely for reinsurance.

EPU power Saving mode- energy-saving technology by Asus, which allows you to regulate the energy saving of the components of the motherboard. As I wrote more - in the camp of dispersal - the strength of "energy savings" - it's evil, we put it in.

Let's go adjust the voltage (pidrozdil digi + VRM) - here it’s more than enough, like it’s bezpomidnyo vіdpovіdat for keruvannya narugogo processor. Tse:

CPU Voltage Frequency- Translatable from the position set to - for manual regulation of the voltage.

CPU & NB Voltage-perekladaєmo z - tse allow you to manually directly indicate the voltage of the work. In the mode, the voltage of the robot is indicated by the sound (plus or minus) rated voltage, Yakim є, yak on the photo is clearly visible - 1.368 V. And such regulation is of no use to us - only the newbies swindle more.

CPU Manual Voltage- for additional keys "plus" and "minus" fixed nominal voltage - 1.368750 Art.

The axis in this manner fixed the entire nominal voltage of the computer, so that the bios automation could not change them. Save bios and reboot.

4. Let's go to OS.

Zavantazhuemo and install it yourself fresh/remaining versions program:

- CPU - Z- for monitoring I will become a processor - a multiplier and a sub-bag frequency of the processor, as well as a voltage.

- Core Temp- CPU temperature monitoring.

- Lin X- A program for setting up the maximum load on the processor. This program navigates the processor with a system of linear alignments of algebra, so that all the cores of the processor are navigated equally, the shards are well parallelized.

For more or less accurate testing of the stability of the processor on the indicated connection [Frequency CPU - voltage CPU ] In principle, it is enough to allow 10 runs in the LinX programs, with more than 50% of total memory usage. For 8 GB of memory, I recommend 5 GB of memory.

In the image below, I have indicated, as you can remember, 10 runs with 1 GB of memory (1024 Mb). MіB (mebibyte) - the same Russian megabyte - 2 20, ale behind the standard behind the MEK standard. So there is no difference, and there is no fear of varto.

5. Vіdkrivaєmo CPU-Z, Core Temp and Linx. We put a charge on them so that the stinks do not respect one alone.

Run LinX in 10 runs.

Let's restart.

6. Let's go to bios.

I more CPU Bus Frequency from 200 to 210 MHz.

How can I mark a parameter Target CPU Speed one hour increases to 3570 MHz. Tobto. we have rozіgnali vіdsotok up to ієї frequency z rated 3400 MHz.

Memory - 1399 MHz.

CPU / NB and HT - 2100 MHz each.

Under the word " slightly agitated toil on the vazі, scho stink at the intervals (+/-) 100 MHz from the nominal frequencies.

7. Let's go to OS.

Run LinX in 10 runs.

Bury the photo!!!

I marvel, the processor warms up to a maximum. Memory of processor productivity in Gflops.

Let's restart.

8. Let's go to bios.

I more CPU Bus Frequency from 210 to 220 MHz.

How can I mark a parameter Target CPU Speed one hour increases to 3740 MHz. Tobto. we have rozіgnali vіdsotok up to ієї frequency z rated 3400 MHz.

Memory became 1466 MHz.

CPU / NB and HT steel at 2200 MHz.

Therefore, the memory frequency did not even "jump" too much like the nominal 1333 MHz, we can change it like in the pictures below (you can also change it with the plus and minus buttons) up to 1172 MHz.

Run LinX in 10 runs.

I marvel, the processor warms up to a maximum. Memory of processor productivity in Gflops.

Let's restart.

10. Let's go to bios.

I more CPU Bus Frequency from 220 to 230 MHz.

How can I mark a parameter Target CPU Speed one hour up to 3910 MHz. Tobto. we have rozіgnali vіdsotok up to ієї frequency z rated 3400 MHz.

At the same time, the frequencies of memory, CPU / NB and HT are increased.

Memory - 1225 MHz.

CPU / NB and HT - 2070 MHz each.

The memory frequencies, CPU/NB and HT are not even adjusted to the nominal ones - that's not worth it.

We save and re-advance.

11. Let's go to OS.

Run LinX in 10 runs.

I marvel, the processor warms up to a maximum. Memory of processor productivity in Gflops.

Let's restart.

12. Let's go to bios.

I more CPU Bus Frequency from 230 to 240 MHz.

How can I mark a parameter Target CPU Speed one hour up to 4080 MHz. Tobto. we have rozіgnali vіdsotok up to ієї frequency z rated 3400 MHz.

Ale - increase the memory frequencies, CPU/NB and HT at the same time.

Memory became 1279 MHz. It’s not a big deal, but it won’t come in at the intervals of 1333 MHz (+/-) 100 MHz.

CPU / NB and HT steel at 2160 MHz.

The CPU/NB and HT frequencies can be reduced to the acceptable 1920 MHz. I'm guessing that the nominal frequencies of CPU / NB and HT are 2000 MHz.

In this way, when dispersing through the bus, we are constantly guilty, so that the memory frequencies of CPU / NB and HT are not far from the nominal ones. Why - I will explain later.

We save and re-advance.

13. Let's go to OS.

Oops! Raptom vinikaє blue screen death - tse means one - for a given frequency of the processor ( 4080 MHz) exposed CPU voltage for bios (for item 3) - 1.368750 V- do not hang.

We press the button reset that revantazhuєmosya.

14. Let's go to bios.

According to clause 3, we know the parameter CPU Manual Voltage- and I’ll redo the “plus” and “minus” keys for help, move and fix the voltage - 1.381250 Art.

We save and re-advance.

Prodovzhennya - tomorrow.

AMD Phenom II 940 BE
Last Tuesday (12 May 2009) "Overclocker Club" Formerly having tested the processor from AMD Phenom II 940. In its time, this vіdsotok shook the whole overclocker world, if the first information appeared, that new one has no cowbug! It allows CPU and AMD to show its phenomenal megahertz. I will change, phenomenal for 4-core processors. All the same, the Intel stone with the NetBurst architecture has not surpassed anyone yet. Also, processors from AMD turned the light overclocking to the sacred world - to try the process of rare helium. And yet, for the time being, only our Finnish comrades have had a dream - SF3D, Sampsa, Macci yakі rozіgnal Phenom over 6500 MHz at temperature -234 degrees Celsius. In Russia, there is still no opportunity to create something similar, and we are satisfied with serial (and not selected in the factory minds) processors, which you can buy for skin in the store, and the "old" cold is cold with rare nitrogen.
Tsey instance of the processor AMD Phenom II 940 Black Edition having drunk before us from sleepy St. Petersburg, de yogo already caught the torment of our pivnіchnі comrades. In addition, the replacement of the thermal interface became the replacement for the Moscow bench from St. Petersburg. DeDaL what time victorist rare metal which allowed us to take away the results.

Test bench configuration:
Processor AMD Phenom II 940 BE 0851APAW
motherboard DFI 790FX-B M2RSH ( thank you to our great thanks to the DFI company for this moment!)
RAM 2 x 1024 Mb Corsair 8500 Micron D9GKX
video card Power Color HD4870 512 Mb
living block Chieftec 1200W

Our hope is that support for the AMD plan - DFI 790FX-B

The launch of the new AMD processor caused a great excitement among the audience OCClub-a, that number of vіdvіduvаchіv pavilion A26+ did not allow the store CUpil.ru ok to practice all day long. Before the speech, everyone who came to this bench session took the cool sets of spins from AMD :).

Jedal "sharpen" his light bottle

While DeDaL was busy preparing the test stand, we all heard Cepreu's report about yoga sleep. The “atdushi” laughed, even if you dreamed that in 2015 the processors were released with a standard clock frequency of 5 GHz. Skoda, only Seryoga, without having killed the CPU-Z validation at the dispersal, relied on his memory, but he guessed: having thrown himself, he couldn’t guess his result.

AMD platform in full stock

Retro frequency on current CPU

Screenshot result at 6.3 GHz

And at the same time DeDaL already showing us our homemade preparations (because it’s called there in KVK) - downclocking up to 100 MHz. Well, now Sarkis from a calm conscience can drink on a calm one - 8 GHz boules, now 100 MHz є.
Burn with fires, and the bottle was filled with nitrogen, and the numbers in the Frequency CPU-Z column quickly beat up to the reserved figure - 6 GHz. At the result, the result was overturned by the best scores: the maximum validated frequency was 6200 MHz, and the lucky ones managed to take a picture of the CPU-Z image and on 6300 MHz.

CPU-Z - maximum validation

About the temperature, you can not dbati

Shukaєmo the best core and ftksuєmo the maximum frequency

Super Pi 1M's best program really hurts

And in the meantime, DeDaL already began to storm Super Pi 1M. Wiish result 11.297 seconds HWBot

High results NB Frequency up to 4200 MHz, What is good!
Let's guess, that these shows managed to reach the serial processor! Behind our special statistics, out of 5 processors, 2 turned out to be even more kind, building power far beyond 6 GHz. Statistics overclocking AMD The Phenom II 940 shows that on the other hand, processes can work on the average at 3.6 GHz, and often there are samples that work at 3.8-4.0 GHz. Well, super-low cold bugs make this 4-core really unique.
Unfortunately, the hour of the benchmark session is not humane, and 3D tests seem to have not been done in the future, but we don’t accept Phenom processors for work, and soon it will be possible to match DDR3 models with DDR2 generations like in synthetic 3D benchmarks, and in real game add-ons.

For now, some screenshots:

Screenshot result 11.297 sec. Super Pi 1M

Recently, the appearance of a new family of core processors Phenom II X4 caused a real furor in AMD's fans, but not only. Overworldly flooded with comments on the address of the new 45-nm processors of the Stars (K10) family, not only fan forums, but also a lot of technological sights, were quick to announce about the release of a new landmark product and the renewal of the competitive AMD and Intel. For an hour, a hard look at the capabilities of the Phenom II X4 does not inspire much optimism. Conducted by us universal testing tsikh processors showed that they can be seen as an alternative to the found chotiria Intel processors, That and that with singing guards. Obviously, in comparison with the old Phenom X4, the increase in the frequency potential of 45-nm cores, which are found in the basis of the new Phenom II X4, allowed to significantly increase the productivity of these processors and significantly improve their thermal imaging and energy saving. However, everything turned out to be a little less so that, given the equal characteristics of processors from the Core 2 Quad and Phenom II X4 families, AMD's propositions looked unequivocally a bigger choice. With renewed confidence, we can only talk about those that the Phenom II X4 can only be compared with some of the core Intel Core 2 Quad processors, which can be seen up to the inexpensive Q8000 series.

Trying to give their new products a bit of extra flair, AMD focuses on their infamous overclocking characteristics. Indeed, in the process of testing the Phenom II X4 940, we easily managed to break out the processor, which can be attributed to the Black Edition series, which is controlled by an unlocked multiplier, from the standard 3.0 GHz to 3.8 GHz with a different superimposed cooling. But, unfortunately, it's not possible to beat the Phenom II X4 processors for the competitors' products. Наприклад, процесори Core 2 Quad Q9400, що мають після нещодавніх коригування прайс-листів приблизно однакову вартість з Phenom II X4 940, здатні розганятися із застосуванням повітряних кулерів до тих же 3,8 ГГц, показуючи при цьому більш високу продуктивність завдяки «широкій» мікроархітектурі Core more quantity instructions per beat.

At the same time, the arguments made by us do not mean that enthusiasts, yak maximum productivity put a cross on the new AMD processors through the rozgіn vinnі. However, there may be interest today not for the older model Phenom II X4 940, but for the cheaper Phenom II X4 920 processor. more low productivity per megahertz through the cache memory, and, moreover, more often through its low multiplier. Thus, since the frequency potential of the Phenom II X4 920 processors is not much compromised by the different capabilities of older brothers, these models as a whole can become the optimal overclocker solutions in their price category.

I will continue to describe the problematics and will assign these materials, in which case we will suggest food, so that we can be true from the point of view of a healthy eye adding Phenom II X4 920 processors for use in a warehouse of overclocking systems. In addition, within the framework of the article, it is possible to date practical recommendations about those, by which way you can reach the fastest overclocking among these processors, if you can’t get a good multiplication factor.

AMD Phenom II X4 920: a closer look

A short guide to overclocking Phenom II processors

Processor frequency how to sound and indicate among the main characteristics. Qia - the most important parameter that the system's firmware code adds: vin sets the frequency that counts the number of processor cores.
The frequency of the processor connected to the pivnіchny bridge. At this frequency, the core of the cache of the third level is used in the processor, as well as the memory controller next to it. For all Phenom and Phenom II models, the frequency is set to 1.8 or 2.0 GHz, the protein also has a big impact on platform productivity.
Working frequency of DDR2 memory- the main characteristic of the memory subsystem, as it is also set, prote, central processor. The choice of frequency is determined by the memory modules that are victorious in the system. Sound in Socket AM2+ systems with DDR2-800 or DDR2-1067 SDRAM, which clocks at 800 or 1067 MHz, obviously.
HyperTransport bus frequency, what is the connection between the processor and the pivnіchny bridge of the logic set. For Phenom and Phenom II processors, use HyperTransport 3.0, the frequency is set to 1.8 or 2.0 GHz.

[CPU frequency] = [CPU multiplier] X [ HT Reference clock];
[HT frequency] = [Multiplier HT] X [ HT Reference clock];
[NB frequency] = [Multiplier NB] X [ HT Reference clock];
[Memory frequency] = [Multiplier Mem] X [ HT Reference clock].

[CPU frequency]: 2800 MHz = 14 x 200 MHz;
[HT frequency]: 1800 MHz = 9 x 200 MHz;
[NB frequency]: 1800 MHz = 9 x 200 MHz;
[Memory frequency]: 1067 MHz = 5.33 x 200 MHz.

Processor life voltage that vikoristovuetsya without intermediary processor cores. For processors of the Phenom II X4 family, it should sound equal to 1.35 V. Safe and such that it may be sensible with even repeated cooling, an increase in voltage to 1.5 - 1.55 V is important.
Voltage vbudovanogo at the processor pіvnіchnogo bridge. A small increase in the voltage can be corny when the standard value of the frequency of the operation of the L3 cache and the memory controller is increased.
Memory life pressure. This characteristic adds to the overclocking capability of the processor only indirectly, allowing additional tweaking of the DDR2 SDRAM system.
