One good tool for that task is Cinebench , which simulates a rendering workload. Extract the archive and fire up Cinebench Windows 64 Bit. When the rendering is complete, it will show you the current score. Write that number down so you can refer to it later if you want to compare scores. Another benchmark tool I like is 3DMark Basic , which is focused on gaming performance.
Learn how hot it gets under this load. Avast Cleanup will automatically get rid of resource-draining apps to make sure your computer is running as smooth and fast as possible. Ready to get started? To access the BIOS, you must turn off your computer and turn it back on.
The exact key combination varies by manufacturer brand and model. This is where to find the settings to overclock the CPU. These options give you a bit of an overclocking boost at safe levels, but the results usually are nothing special. The first step to increase the clock speed should be to increase the multiplier. This uses the base clock built into the motherboard usually MHz — multiplying that number yields your clock speed.
For example, a multiplier of 36 x MHz gets you 3. Gradually raise the multiplier one step at a time. Proceed slowly and treat this as an iterative process. Speed up your computer a little bit. Then, if all goes well, go back and speed it up some more. In the case of the test Coffee Lake sample used here, 1. Note that as voltages rise, so do temperatures, and the curve is not linear. After 1. Since every chip and motherboard has different potential, you need to test your unique setup to find the sweet spot for that rig.
While you may see gonzo overclocking pros push Intel's stated 1. Check system Stability after each clock increase, using the same programs as before.
AIDA64 is also a good option here. AIDA64 combines system information, synthetic benchmarking, monitoring, and stress testing into a single, modern package. For stress testing, use the system stability test on the tools menu.
Processors run hot when AIDA's FPU test is executed by itself, so take solace that actual full-load temps will be a few degrees lower in typical use. Consider it a safety margin against throttling. Once you have a stable overclock, run the benchmark suite again and compare results with your initial scores to take stock of your gains.
Coffee Lake's six or eight cores and the VRMs on many Z and Z motherboards run warmer than their predecessors, so don't be alarmed if idle temps are higher than Kaby Lake or Skylake. Much past that point and you potentially shorten the life of the CPU due to thermal degradation.
We've burned out CPUs in the past, or had once-stable processors require lowering the clockspeed below stock after pushing them too far. You've been warned: High temperatures are really not good for your CPU.
The uncore, or system agent, takes care of all the system processes not performed by the main CPU cores, such as integrated memory controller and cache functions. While boosting the uncore frequency can result in minor performance increases, the main benefits to adjusting the uncore come from reducing it.
If your CPU is having problems going past 4. Any performance lost with lower uncore speeds is more than returned via higher core clockspeeds. If reducing uncore doesn't help free up more GHz or results in instability, restore it to its former value or try a slight boost. Uncore is also referred to as the cache or ring ratio on some motherboards; the exact term depends on the manufacturer. Intel's latest CPUs provide a series of updated AVX instructions, which are designed to accelerate audio, video, and image processing functions.
However, these greatly increase the power usage and heat produced by a CPU. This feature detects AVX workloads and adjusts the multiplier downward by a specified value to maintain system stability, so a system overclocked to 5GHz with an AVX offset of 2 would adjust to 4. Applications that make use of AVX instructions are more common these days, and it pays to check system stability under such workloads.
Cinebench R23 is a good option for AVX testing. If you find a hard limit with these tests or with other AVX packages that you use frequently, adjust the offset to compensate so you can keep the overclocking gains found in typical CPU workloads without crashing.
As an example, our Core i7 K can hit 5. Even so, they shouldn't be hard to locate. Find the section that deals with your CPU. Once you reach the CPU menu, you'll see a host of different options. You can adjust both, but start with the CPU multiplier. For you. World globe An icon of the world globe, indicating different international options. Get the Insider App. Click here to learn more.

Most processors have a little extra headroom, and if you know how to overclock your CPU, you can take advantage of it for higher frame rates in games, faster renders in Adobe Pro, and everything in between.
You can overclock memory , too. When you overclock a processor, a couple of things happen. The chip runs hotter and uses more power. After all, increased power and heat will degrade most PC components faster. Few allow it, and fewer still possess the thermal headroom to make it viable. But even if you can, we caution against it for your first overclocking venture.
Finally, overclocking your CPU can void its warranty. Motherboard manufacturers may or may not cover overclocking. Before you start overclocking the CPU, figure out what you have — the chip may not even support overclocking in the first place. If it does, determine its theoretical maximums with a little research. Which processors you can overclock is an area where AMD and Intel differ significantly. Below are several recent unlocked Intel processors primed for overclocking.
AMD processors have remained completely unlocked and overclockable for generations. The last several generations of Ryzen CPUs support overclocking, including the recent Ryzen chips. If this is your first overclocking attempt, give your PC a spring cleaning.
You can clean the dust filters on your front intake fans or remove all hardware and wipe down every surface inside.
Before cleaning, turn off the PC and wear an anti-static wristband. If dust is hard to reach, use a can of compressed air. 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.
