Officially, this is set at 4.8GHz on the Core i9-10900K. The base multiplier value, for Intel CPUs, is derived from their all-core boost clock. Just check the value of the base multiplier (All-Core Ratio Limit setting) and increase it by one during each OC step. This is why you shouldn’t load up results and settings found online and should start from scratch instead. Then there’s the cooling performance, memory frequency, and timings, etc. If you have a golden sample, you’ll manage to reach higher clocks but if you have a below-average sample, your OC results could be very limited. Remember that CPU overclocking highly depends on your luck in the silicon lottery. This is to prevent throttling when dealing with AVX instructions. Once in there, you want to find settings called “CPU Core Ratio” and “All-Core Ratio Limit.” First of all, set the CPU Core Ratio to “Sync All Cores.” Next, look for the “AVX Instruction Core Ratio Negative Offset” (it should be in the same menu) and set it to zero.
RYZEN CPU STRESS TEST 1080P
You could also test a CPU-intensive game (like Shadow of the Tomb Raider) at 1080p and low settings to get the baseline gaming performance numbers. A couple of runs of Cinebench will do the trick. Okay, before you dive into BIOS settings, test your CPU on stock settings to get the base numbers when it comes to performance and thermals. HWiNFO is the most robust one and we wholly recommend it.įinally, while we’re explaining the overclock process via BIOS, you can also use Intel’s Extreme Tuning Utility. Prime95 is still the best choice but we would also like to mention OCCT, which comes with a plethora of stress tests that are handy for overclocking the CPU, but also for OCing the memory or the GPU.įor performance testing, there’s Cinebench (it doesn’t matter whether you’re using version 20 or 23) and you can also get a couple of games with built-in benchmarks to test performance and stability. What You Needįirst of all, you’ll need a CPU stress test utility. First of all, let’s gloss over the apps you’ll need for overclocking.
RYZEN CPU STRESS TEST MANUAL
Unlike Ryzen CPUs, which include several ways to overclock, Intel CPUs use the good old manual OC that includes tweaking the frequency multiplier. You’ll see performance gains in multithreaded loads, but they won’t be anything to awe at. 1 performance, which can lead to more fluid gameplay. In some cases (like when using AMD’s PBO 2) you can get higher. This can lead to degradation in performance, especially when playing games that are very sensitive to higher single-core clocks. Their specs include single-core boost clocks that are often higher than potential all-core overclock maximum values. Flagship CPUs are already pushed to their limits with aggressive boost clocks. We will also explain the differences in overclocking Intel and AMD CPUs.īefore we start, do note that overclocking modern CPUs won’t give you a whole lot of extra performance.
RYZEN CPU STRESS TEST HOW TO
Today, we’re going to answer the question of how to overclock your CPU.
That said, overclocking your CPU can give you extra frames in games and noticeably shorter render times. These days, both AMD and Intel push their CPUs to limits with dynamic boost features so there’s not a lot you can do to get extra performance. Back in the day, you could get a completely new CPU simply by increasing the clock of your current processor. Glory days of CPU overclocking are long gone.
