Beyond air cooling, there is liquid cooling and phase change cooling. These systems are far more complex and expensive than standard PC cooling solutions, but they offer higher performance at heat dissipation and generally lower noise.
Well-built systems can allow the overclocker to push the performance of their hardware to its limits, but the cost can end up being more expensive than the processor cost. The other drawback is liquids running through the system that can risk electrical shorts damaging or destroying the equipment. There are a lot of factors that will affect whether you can overclock a computer system.
The first and foremost is a motherboard and chipset that has a BIOS that allows the user to modify the settings. Without this capability, it's not possible to alter the bus speeds or multipliers to push the performance.
Most commercially available computer systems from the major manufacturers do not have this capability. Those interested in overclocking tend to buy parts and build computers. Beyond the motherboard's ability to adjust CPU settings, other components must also be able to handle the increased speeds.
Buy memory that is rating or tested for higher speeds to preserve the best memory performance. The frontside bus speed also regulates the other interfaces in the computer system. The chipset uses a ratio to reduce the frontside bus speed to match the interfaces. When the frontside bus is adjusted, these buses will also be running out of specification unless the chipset BIOS allows for the ratio to be adjusted down.
Keep in mind that changing the bus speed can impact stability through the other components. Of course, increasing these bus systems can also improve the performance of them, but only if the parts can handle the speeds.
Most expansion cards are very limited in their tolerances, though. If you're new to overclocking, don't push things too far right away. Overclocking is a tricky process involving a lot of trial and error. It is best to thoroughly test the system in a taxing application for an extended period to ensure the system is stable at that speed. At that point, step things back a bit to give some headroom to allow for a stable system that has less chance of damage to the components.

Unlike some third-party software, the Intel XTU is stable, reliable, and unlikely to cause problems independently.
Intel XTU may look a little intimidating at first, given its many highly-granular options. But once you grow familiar with the tool, everything makes sense. The reams of information become highly useful. Start by running Stress Test located on the left-hand menu.
Run this test for at least an hour. You can sit and watch the test or do something else. Take note of the Package Temperature. We recommend improving your cooling before continuing any further.
If your temperature is below that — preferably well under it — you have some thermal wiggle room to push your chip at a higher frequency with relative safety. It also makes it easier to achieve a stable overclock. Select the Advanced Tuning tab from the left-hand menu and then look to the section headed Multipliers.
A x32 multiplier would typically mean a turbo frequency of 3. Raise your multiplier by one number x33 in our example across all cores. Select Stress Test from the left-hand menu and rerun the test. In this case, you only need to run the test for 10 minutes. If it completes without a problem, increase the multiplier by another step. Rinse and repeat. Eventually, the test will report a fail result, or it will cause your computer to crash. When that happens, step back to the previous multiplier setting.
If not, reduce the multiplier another step and begin the stress testing process again. When you reach a point where you can happily use your PC as usual at a higher frequency, pat yourself on the back for a successful overclock! If you run into difficulty trying to stabilize your overclock or want to see if you can push the system further, try adjusting its voltage. This process can differentiate between unstable and stable overclocks, or even the difference between modest and much higher overclocks.
But be warned: You need to take more care when adjusting the CPU voltage than you do with multipliers. If you push the CPU to run at a ridiculously high multiplier, it will just crash and restart your system. If you try and force too much voltage through your CPU, it can kill it, so proceed with caution.
Use Google to see what settings other people use for your specific CPU, especially for VCore settings, given its potential to damage the chip. Overclocking refers to pushing the clock speed of your processor past its rated limit.
So, a 4GHz processor can complete 4 billion clock cycles per second. All things being equal, a 4GHz processor can complete more instructions than a 3. You can overclock to achieve higher clock speeds, which in turn, allows your processor to complete more instructions each second.
Overclocking typically involves the primary processor, though you can also overclock a discrete GPU for a boost in graphics processing. There is no one rule in how fast you can speed up a processor, and every overclocking project produces different results. That makes your decision to overclock rather difficult. Overclocking can be time-consuming and expensive, especially if you have little experience tinkering with PC components.
In addition to changing your multiplier, you may need to alter voltage settings, fan rotation speeds, and other important, fragile fundamentals. Like most things, it depends. Gaming is a big reason to overclock, and depending on the game, it can make a big difference. In games, the CPU is best known for handling A. Your CPU handles more than A. Spare cores often go to handling simulations, from cloth to explosions, and some games even offload audio processing to the CPU.
This division of labor is becoming increasingly common, especially as core counts push higher on consumer processors. As resolutions go higher, games become GPU-bound and show little performance gains from overclocking. Similarly, games that favor more cores over faster cores, such as Cyberpunk , show less of an improvement with an overclocked CPU. Outside of gaming, overclocking can boost performance in 3D modeling, video editing, and image editing applications, to name a few. Basically, any application that demands a lot from your CPU will benefit, if only slightly, from an overclock.
As with gaming, the same rules apply to other applications. Certain software favors more cores over faster ones, so your mileage will vary from application to application. With high-end components, moderate overclocks produce marginal performance gains in most cases. Furthermore, if you play a lot of CPU-intensive games or use applications like HandBrake, overclocking can give you a significant performance uplift, even at moderate settings.
