To be safe, simply increase the multiplier by 1x, then run the XTU benchmark. Each tick of the multiplier is 100 MHz of speed you’re adding to your CPU.

The key tool here is the multiplier, which you want to increase for all cores. Once you’re back in Windows, run XTU’s Memory Stress Test for at least a few minutes to make sure the XMP profile is stable. After applying this profile, you’ll need to reboot. Profile #1 is always a good starting point. This overclocks your RAM to a predetermined speed that should be stable. Now, if your motherboard BIOS provides memory information, it’s time to enable an XMP profile. Worst case, your power bill goes up a little bit. Don’t worry about them damaging your CPU these limits will ensure the CPU gets the maximum amount of power it needs from the PSU so it’ll never be throttled, but it isn’t dangerous there are still safeties in place that will protect the CPU. You can turn these sliders all the way up. There are a couple of settings Pineau recommends changing before you start adding speed: the Turbo Boost Power Max and Processor Current Limit.ĭepending on your system, you may also have a Turbo Boost Short Power Max option to increase as well. This will give you a reference point for how much faster your PC is once you’re finished tuning it. Run XTU’s built-in benchmark before you start overclocking and upload your score to HWBot if you’re interested in keeping a profile. You can go to a third decimal point if you want, but it's not really necessary.Overclocking with Intel's Extreme Tuning Utility Keep doing this until it is no longer stable, then set to the last stable voltage. Check stability and temps while stress testing, if stable after 10 minutes, go back into BIOS and reduce voltage by. Go to "Internal CPU Power Management", set both Short Duration and Long Duration Power Limits to max (4095).Change CPU Core/Cache voltage to Manual, 1.30v.Set CPU Core/Cache Current limit to 9999 (should change to 255.70 or something similar).in "External Digi+ Power Control" set Loadline Calibration (LLC) to level 6, and CPU Current Capability to 170%.Set CPU Core Ratio to "Sync All Cores" and set the multiplier to 50.If you would like to try a basic, but likely stable, 5Ghz overclock, reset everything in the BIOS to default and then follow these steps: I strongly recommend never using profiles for overclocking as they generally overvolt like crazy since they are generic profiles. If 3 or 2-4 cores are, it will drop to 4.8Ghz, and if all 8 are loaded it will go to 4.6Ghz (which is what you saw). Only time the stock 9700k will boost to 4.9Ghz is if 1 or 2 cores are under load ONLY.
