All modern computers are multi-core devices that affect system performance. However, Windows 7, like any other operating system, does not use the processor cores at full capacity. This is due to the saving of resources of the PC itself. Therefore, if your programs do not slow down and errors do not crash, we do not recommend using all the cores of the graphics accelerator. This action should be performed in cases where the power of the PC is not enough to run standard programs and games.
Configuring the operation of kernels through the startup menu
This option for using all the power of the processor is the simplest and safest. It is suitable for all versions of Windows OS (except XP). Any user, even a beginner, can follow these steps.
- Press "Win + R" and enter "msconfig".
- The System Configuration window will open. Go to the "Download" tab and click "Advanced options".
- In the window that appears, put the "Number of processors" checkbox so that the item with the choice of cores becomes active. We set the maximum memory.
- Then we save the result and reboot the system. Multitasking mode will turn on.
IMPORTANT! If your PC shuts down with advanced settings, check if your power supply has enough power.
Advanced processor settings with AIDA64
The AIDA64 program is useful not only for its reports on the status and characteristics of individual PC components, but also for unlocking processor cores. To use the capabilities of the CPU using this program, you should do the following:
- Run the program and select "Motherboard", "CPU" from the menu on the left.
- Next, turn on each of the kernels and reboot the system.
If the kernels involved did not bring benefits, it is worth returning the settings back.
Engaging processor cores with CPU-Z
The CPU-Z program allows you not only to check what characteristics this or that PC component has, but also to optimize the operation of some of them. In order to enable all cores, you must do the following:
- We launch the program. Go to the "CPU" tab.
- In the "Theads" item, you need to set the same value as in "Cores".
- After rebooting the system, you need to check the changed parameters.
Overclocking the processor using BIOS settings
To use all the cores of the graphics accelerator, you should go to the BIOS. To do this, restart the PC and press "F2" or "Del" several times. Then you need to make the following settings:
- We find the section "Clock Calibration" (It is available only for AMD products). We set the value "All Cores". In the "Value" item, set the value as a percentage.
- After rebooting the system, it is worth checking the PC for operability.
These methods are quite simple and in rare cases cause the system to crash. However, if errors start to appear after editing the settings, you should stop unlocking the kernels and return the settings back.

We all know that computer hardware manufacturers put a lot of capabilities into their components. But greedy marketers sell it in chunks, turning off many features and hiding blocks from use. Let's learn how to enable hidden features.
ENABLE AMD PROCESSOR CORE
Many processors contain hidden cores
Almost all AMD processors, especially the Phenom II X6 and FX-series, are subject to this modification, since they have hidden cores.
As a rule, 1-2 hidden cores are turned on, and in the case of FHs, quad cores become FX-4300 => FX 6300 with six cores, FX 6350 = FX 8320 with eight cores, and FX 8350 => FX 9590 5GHz becomes a top processor !!! To do this, enable the UCC Unlocker function in the BIOS.
ENABLE INTEL PROCESSOR CORE
The same thing happens with INTEL processors, with the only difference that the L3 cache is often also enabled on lower processors. To activate, you need to update the BIOS to unlocked Unlock intel BIOS and enable the corresponding checkbox.
Overclocking CPU Intel Core i3 / i5 / i7 without multiplier "K"
Alternative BIOS allows overclocking all Intel processors
Everyone also knows that Intel processors with an unlocked K multiplier are absolutely no different from those without a multiplier, except for an overpriced. However, they can be overclocked with the bus by increasing the base FSB from 100 MHz up to 200 MHz (i.e. 2 times!), Or open the multiplier by updating the BIOS with the same Unlock intel BIOS
INCREASE HDD CAPACITY
It's no secret that the platters for hard drives are made of STANDARD volume. Then WHETHER, you say, are multiple HDD capacities, say 750GB ???
That's right - the manufacturer simply locks on one or several platters the amount of hard disk that can and MUST be unlocked!
To unlock, we need the Acronis program.
1.) You should first change the type from MBR => GPT in the disk settings and make it dynamic so that hidden areas can be freely addressed by the operating system.
2.) You need to demagnetize your hard drive with a powerful magnet to erase the factory lock code.
3.) Using the Acronis utility, select any desired HDD size.
DISCONNECTING HDD BITLOCKS
It's always nice to programmatically fix the hard drive
The same manipulation, only in reverse order, should be performed to block the broken areas. In this case, even a sprinkled hard drive will work like a new one. That being said, remember that it is easy to recover any lost data on the HDD, as it is always backed up to hidden factory partitions. To do this, again, you just need to enable them as described in the chapter above.
ENABLE ALL SHADERS ON THE RADEON VIDEO CARD
R9 290X unlocked from a simple Radeon HD 7730 1Gb
Radeon and GeForce video cards, among other things, differ in that Nvidia is not lazy to make a separate chip for each new video card, but AMD usually simply turns off some of the shader units of older video cards to make the younger ones. Judge for yourself, video cards such as the Radeon HD 5850 and 5870 have the same chip, and the shaders are 1440 and 1600, respectively. The same goes for the R9 280-280X, etc.
To enable all Radeon shaders, you need to install the GeForce driver on it in safe mode as on a standard VGA device (overload by pressing F8).
Unlocking significantly increases the speed
ENABLE ALL CUDA Cores NVIDIA VIDEO CARD
Here it will be more difficult ... It is necessary to close the jumpers on the VGA port with penny resistors as shown in the figure.
This manipulation includes all blocks of GeForce graphics cards
The resistor parameters do not matter. This method also makes professional TESLA series out of all video cards, and also fights artifacts.
INCREASE IN POWER SUPPLY POWER
High voltage can KILL! Don't do this))
Almost all Chinese power supplies differ only in the size of the cooling radiators. Therefore, it is enough to simply open the cover and install another fan on the power supply unit, and you can even hang an SLI GeForce 780Ti or lower-end video cards unlocked before it on a 400W power supply unit.
Do not forget that the article was written solely as an April Fool's joke :) and we are not chasing the ball. It should be noted that in skillful hands, some things really do succeed. But there is much more benefit if you correctly configure the configuration and select the components specifically for your task.
Spring mood for you!
The article will discuss the possibility of including the third and fourth cores, and also the practical results of such an action will be given - that is, tests. After all, it is very tempting to get a platform with a top-end processor for a hundred dollars.
Regarding, but one of the main consequences of AMD's "poverty" is RATIONAL use of the crystal area.
AMD much earlier than Intel, and even on the old technical process, still managed to create the first quad-core processor on one die (Intel made its quads by soldering two dual-core processors).
So - the processor is made, but the marriage is still present from time to time even in a rich intel (fresh news - ). So AMD, for example, has suspicions that one core is not working. They simply block it and you buy some kind of three or even dual-core processor AMD Phenom II 560 X2 Socket AM3 3.3GHz 7MB 80W box or Athlon II X3 445. But physically - it is FOUR-CORE!
How do I unlock / enable AMD processor cores?
Save changes and reboot - if everything goes smoothly, then the first step will pass. But only the FIRST.
Do not forget that the nuclei for Athlones and Phenomas are blocked for a reason and they can be malfunctioning. Next, you MUST test ALL processor cores for stability, for example, as described in the article.
PRACTICE
An Athlon II X3 425 processor was taken and with the help of AsRock's cheap motherboard option - Bios Unlock CPU Core, the fourth core was enabled.
This is how the processor looked BEFORE unlocking:
As you can see, the CPU-Z utility determines that the processor has three active cores and each has half a megabyte of L2 cache.
Now we turn on the fourth core ...
Disappointment awaited. The very first test revealed the inoperability of the included kernel. It was functioning, but under load it failed. Looking closely at the picture, you will also see artifacts of the desktop image. But something else is noteworthy - the Athlon II X3 processor has turned not into a quad-core Athlon, but into Phenom II X4 !!!
The screenshot clearly shows from the utility's readings that not only the kernel was turned on, but also the extra 6MB of L3 cache.
I decided not to give up and go all the way. Through trial and error, it was revealed that the PHYSICALLY malfunctioning locked core is the second in a row. What if the L3 cache is perfectly functional? To verify this assertion, the processor was unlocked again, but the second core was disabled from the application manager.
We are passing the test ...
The test worked flawlessly. And at the same time, we also figured out the practical benefits of a large cache. In the 3D Mark 2006 test, its presence, other things being equal, in some places added + 10%. This is certainly not an extra core, but still an increase. Smart motherboard manufacturers, even specifically for such cases, provide for the associated shutdown of faulty cores.
That is, first we will forcibly unblock everything that can be unblocked, and then we block what is inoperable)))))))))))))))
There is still a fly in the ointment in all this. Even in spite of the fact that the cache and cores are inactive, such processors still have a large die size and noticeably heat up. Consider this.
WHICH PROCESSORS ARE SUITABLE FOR UNLOCKING?
Three-core Athlones and two-three-core Athlon-II-X3 and Phenom-II-X2-3 are suitable. There is also a rumor that some quad-core models are unlocked into six-cores, but there is no such experience yet. Then look for the Phenomes on the Thuban core and it is quite possible that you will be lucky.
OUTPUT
In general, in this case, I was not lucky, because I could get a 100% working copy. In that case, I would get a $ 150 quad-core Phenom II X4 out of a $ 65 processor. Agree - this lottery is worth it. And it is especially pleasing that even penny motherboards can do this.
Introduction
History has to repeat itself often: manufacturer X, known for its flagship product Y, recently launched a mid-level product Z, which is built on a silicon crystal that for some reason does not reach Y. But instead of throwing out the crystal, X turns off his a certain part, and then sells it as Z - at a lower price.
As a rule, in most cases (but we do not know how large such a majority are), this is due to the fact that the kernel does have a defect. But sometimes a manufacturer just needs to release processors of a certain price level, which are in short supply. ATI Radeon HD 4830, nVidia GeForce GTX 260, AMD Phenom II X3 700 and 800 lines are all examples of products based on more expensive components.
AMD Phenom II
For testing purposes, we bought a retail version of the X3 processor. Click on the picture to enlarge.
A couple of months ago from Korea information came, which said that you can simply unlock the fourth core on the Phenom II X3 processor by enabling the Advanced Clock Calibration function on some motherboards, which turns the Phenom II X3 720 Black Edition for $ 135 (from 6 thousand rubles in Russia) into the Phenom II processor X4 920 (Black Edition) for $ 190 (from 6.9 thousand rubles in Russia) by changing the option in the BIOS. For now, we will bypass the question of whether it is worth saving to get a potentially unstable system.
Do you remember from our Phenom II market entry article AMD said that ACC technology does not technically change anything for the Phenom II, since it is already integrated into the Phenom II. The very same ACC technology allowed the Phenom to reach higher frequencies after overclocking. Now, this feature of the SB750 southbridge seems to have impacted the Phenom II in a different way.
How it all works remains a mystery to us. Two motherboard manufacturers, ASRock and Biostar, have said they support the ability to unlock the X3 processors, but neither company has explained how this happens. To be honest, this is unlikely to be due to any trick on the part of the companies, and something like this is probably happening: ACC can change the process of checking the CPU for errors, increasing error resistance and reducing the chance of failure under certain conditions. In this case, the increased robustness of the ACC made it possible to "revive" the disconnected silicon section.
We also bought a retail version of the X4 processor. Click on the picture to enlarge.
Biostar's product manager said that any board with the SB750 southbridge could have the same unlocking effect. ASRock confirmed this, and also provided us with its own test data for a certain number of processors, where there is a fairly even distribution on chips that are unlocked and work stably; chips that are unlocked but are unstable; chips that are not unlocked at all.
And here's what's interesting. AMD says the hype surrounding the ACC / Phenom II X3 has boosted sales for a product line that we didn't think was in high demand. After all, after the first release of X3, many applications simply didn't know what to do with the three cores. And the company says it has no plans to stop enthusiasts from unlocking the fourth X3 core by enabling ACC on the SB750.
But one motherboard manufacturer told us that AMD plans to end ACC support in the SB750 southbridge this month. Another vendor said AMD is pressuring it to update the onboard ACC controller firmware and publish an "updated" BIOS. And if the first is an assumption, then the second seems to be true. Indeed, free cheese only comes in a mousetrap. Proof? Slightly below.
Kernels and cache
It looks like the X3s aren't the only models that can do more. AMD chips from the Phenom II X4 800 line (those with 4MB of L3 cache instead of the full 6MB) can also be unlocked using the ACC trick, although the benefit seems questionable in this case. The Phenom II X4 810 processor cost $ 167 on Newegg.com (6.8 thousand rubles in Russia) at the time of publication of the article. Phenom II X4 920, working at 200 MHz faster, cost $ 189 (6.9 thousand rubles in Russia). Of course, the 810 belongs to the Socket AM3 generation, and the 900 line is currently limited to AM2 +, but AMD will update the Socket AM3 line with top models in the near future, so it hardly makes sense today to limit yourself to AM2 +, especially if you plan to switch to DDR3 in the future.

But let's get down to the real hardware and see if we can get a stable system after unlocking less expensive processors. Of course, it hardly has to be repeated once again that even with the standard clock frequencies, here we have the same consequences as after overclocking. That is, no one will provide technical support for this step, except for the community of enthusiasts.
Not all motherboards are compatible
First, we decided to choose a Socket AM3 platform suitable for testing. We already knew that ASRock and Biostar are the two manufacturers who initially supported this idea. And in our Club of Experts, readers asked to conduct similar tests.
We started with tests of the Asus M4A79T Deluxe, which, judging by other sites, must work. But nothing worked. With ACC disabled, the board worked well. As soon as this feature was turned on, our Phenom II X3 720 (which we knew was successfully unlocked) started to constantly blue screen. We were using the latest BIOS from Asus, so we used a different motherboard with an older BIOS.
The next was the Gigabyte MA790XT-UD4P motherboard. We received this board with BIOS F2 dated January 16, 2009. However, this did not help to unlock our "successful" Phenom II X3. On March 10, Gigabyte released BIOS F2B, which was supposed to update the ACC code for the Phenom X3 processors. We updated the BIOS to the latest F3, but that didn't help either.
We contacted Gigabyte to find out what is meant by "ACC code update". According to the company, all manufacturers developing new BIOSes with the latest AMD microcode should disable the kernel / cache unlock feature, which at least explains why ASUS and Gigabyte motherboards with the latest BIOS have refused to cooperate with us. Why not use old microcode? The latest microcode fixes many other issues, including, for example, the accidental reboot issue. From the point of view of the motherboard manufacturer, releasing a more stable BIOS is still preferable to leaving the unsupported and potentially problematic hack feature. In general, if you want to keep your hacked Phenom II, you need to stick with the BIOS version before fixing it.
The ASRock M3A790GXH / 128M is the only board in our lab that was still able to unlock all Phenoms. Click on the picture to enlarge.
Finally, we took a board that should be guaranteed to work: ASRock M3A790GXH / 128M. Oddly enough, even with the ACC function set to Auto, the board included the fourth core Phenom II X3 720 under Windows. ASRock has released only one BIOS version for this motherboard - the original. Perhaps after a while there will be a BIOS update and the board will lose its unlock functions?
ASRock told us that the company is in no rush to include the latest microcode fixes. If AMD releases new processors or fixes bugs that it deems critical to a microcode update, then the consumer will be presented with two BIOS versions, and enthusiasts will be able to choose one or the other.
And not all processors either
In the end, we tested three Phenom II X4 810 processors and three Phenom II X3 720 Black Edition processors. One processor each was received from AMD as samples. We got one processor each from ASRock - these were guaranteed unlock models, which we used to test if we could unlock processors on other motherboards. Finally, we bought the last pair from Newegg to get an idea of the unlocking capabilities of retail processor versions.
Of course, we have successfully unlocked two processors from ASRock. The Phenom II X4 810 from AMD is working as well. But we couldn't unlock Phenom II X3 720 BE from AMD. The Phenom II X4 810 purchased from Newegg has been successfully unlocked. The Phenom II X3 720 failed.
The processors we were able to unlock normally had the ACC function set to "Auto" in the BIOS of ASRock motherboard. The X3 720 sample we sent to ASRock passed all our tests perfectly at this setting, showing the performance advantage of enabling the fourth core. We then ran the Prime95 benchmark to test the stability. After just a few minutes, the platform froze, and after the reset it started reporting only three cores - even with the ACC function enabled.
We have already read about this behavior, when unlocking the processor "does not take root". Fortunately, this allowed us to find a way to get the unlock back, even if it fails, back.
Unlocked X3 720, ACC On.
Normal X3 720, ACC off.
We started to change the ACC setting to modes other than Auto, using the All Cores option. By changing it in 2% increments, we were able to bring the fourth core back at -6%. And while the system was previously unable to pass the Prime95 test at all, in this case it worked normally for an hour without errors before we turned off the computer. It looks like a more aggressive ACC setting can stabilize the unlocking of the fourth core.
However, ACC does not work miracles. On two of our Phenom II X3 720s, on which the core was not unlocked even in the "Auto" position, we changed the ACC setting from + 12% to -12%, and we still did not find any signs of a fourth core.
Unlocked X4 810, ACC included.
Normal X4 810, ACC off.
Processor Results
| CPU | Model number # | Week and stepping | Unlocking capability |
| Phenom II X4 810 from AMD | HDX810WFK4FGI | 0849 CPBW | Yes |
| Phenom II X4 810 by ASRock | HDX810WFK4FGI | 0848 DPM | Yes |
| Phenom II X4 810 by Newegg | HDX810WFK4FGI | 0903 CPAW | Yes |
| Phenom II X3 720 from AMD | HDZ720WFK3DGI | 0849 CPMW | No |
| Phenom II X3 720 by ASRock | HDZ720WFK3DGI | 0849 CPMW | Yes |
| Phenom II X3 720 by Newegg | HDZ720WFK3DGI | 0904 EPMW | No |
The results look best for the AMD Phenom II X4 810, regardless of when this processor was produced or what stepping it may have. In all three cases, we were able to unlock and add 2MB L3 cache on the ASRock motherboard.
The central processing unit (processor core, CPU) is a device for processing the program code of all processes that run on a computer. The processor is an integrated circuit for manipulating logical tasks and working with complex computer programs.
The main processor meets such standards and properties as:
- Performance (speed of information processing by the processor)
- Clock frequency (quantitative characteristic of issuing processor cycles per unit of time)
- Architecture (some properties and quality characteristics of the equipment, for example, the internal wiring of the processor, features of working with graphics)
- Energy consumption
The processor is the brain of your computer. The essence of the operation of this device lies in simple mathematical operations of addition, subtraction, division and multiplication. But in combination with your software, the processor, using the system commands or microinstructions written in it, connects the entire computer device into a single whole.
To know how to unlock a processor, you first need to understand for yourself that not every processor needs to be unlocked. After all, there are different processors, but the main suppliers are such companies - giants as Intel and AMD. The share of their developments in the microprocessor market is practically equal. The constant war for customers gives users new processors, upgrades to them, of course, not without sins.
Processor unlocking is used only in some models of AMD (AMD Phenom II, Athlon II, also cores marked X2 and X3). What is the essence of the problem, is that unlocking the processor cores is a manipulation of the crystal. That is, AMD, in order to save money and, accordingly, release its product faster, replaces its processor core crystals with less quality ones, with defects. These "defective" crystals are blocked due to the fact that they simply cannot withstand high frequencies and high temperatures. But to unlock the cores of AMD processors, it is not necessary, as they say, to perform "dances with tambourines" over it, because the structure of the crystal itself is easily unlocked or "unlocked".
And so, in order to know how to unlock the processor core, you need to perform the following actions:
- You should understand that removing the unlock leads to a rise in the temperature of the central processor, that is, you will need to install additional or more powerful cooling for your core. Because when overclocking the processor, it can burn out.
- The very same unlocking does not require the installation of any programs or applications. You just need to go into the BIOS shell. In different motherboards, the shell start buttons are different (for example: at the bottom of the screen, when you turn on the computer, you will see: "Press DEL to run Setup")
- If you have an Asus motherboard, then unlocking is done with the F4 button. If it is Gigabyte, you will see the IGX Configuration tab in the BIOS menu. Further, when you press "Enter" you will see two items "Enabled" and "Disabled". Choose the second one and turn on the "unlock".
- By pressing the F10 key, you save the settings and reboot the system. The operating system, after this manipulation, may issue a blue screen, which is "fatal" for Windows. This means that the processor core is still defective and you need to return all the parameters back.
- If you do not see a blue screen, then you still need to check the system for errors.
Note: unlocking the core of AMD processors is a lottery for users. Because only the third / fourth processor is possibly unlocked. There is also a problem with "unlocking" not all processor cores. That is, for example, one core is working fine, while the other is only half its capacity. If you yourself, thanks to the instructions, did not manage to unlock the processor, contact the service center or specialists.
