Issues that arise during overclocking of the i5 7600K
Hello everyone,
I’m facing some unusual problems when trying to overclock my i5 7600k.
Here’s what I’ve been doing and the issue:
My system specs are: i5 7600k, AS Rock Z270 Pro4, 16 GB DDR4, MSI GTX 1060, Windows 10 Home x64, updated BIOS 2.70, Silentum PC Fera 3 (1224 v2).
I’m only using CPU ratio and voltage to overclock. I can adjust the CPU ratio to 45 with a voltage of 1.250 and the PC boots fine. I run Prime95 (version 29 build 8) and it works without errors, temperatures stay around 80-85°C while under heavy load, peaking at 93°C but usually around 78°C.
Tests are smooth until I reboot. After rebooting, Prime stops working completely or triggers a BSOD with a timeout watchdog error. It doesn’t matter what CPU ratio or voltage I use—it always freezes the PC after reboot.
I’ve tried:
- Changing voltages and CPU ratios—still freezes after reboot.
- Setting voltage to auto and ratio to 42—it works normally, tests pass, and after reboot it functions again (turbo boost is 4200).
Why does this happen? It seems the problem occurs only when I manually set the voltage, suggesting an issue with manual adjustments.
Any suggestions would be greatly appreciated!
Thanks!
Adjust your cache settings below the CPU speed, keep it at 40 and enable minimum cache auto. Proceed from there, letting the CPU handle whatever frequency you aim to reach. The CPU core limit should be manually configured rather than left auto, as I set it to 180 for my Z170 overclock of 6600k. This only affects throttling and shouldn’t cause crashes. You can still try it, though, since auto usually defaults to around 120, which matches stock speeds. Auto doesn’t automatically adjust for performance needs.
Do you rely on BIOS/UEFI for overclocking or employ a different method within Windows?
Hey, thanka for replies.
First of all i use UEFi to overclock.
Second there are no issues while running stock settings.
I think voltages are being saved aswe, will confirm this evening.
I remember seeing something similar in a thread related to an ASRock MB, where it was mentioned that adjusting a power/temperature limit in the BIOS to 1xx% might be necessary for proper OC and clock rate considerations. Please verify your BIOS settings for any available options.
Hey,
I did not see the option you talk about, here are pics of my Bios

now here is the kicker, someone told me to try what i am doing just with Prime95 v26.6 and the tests passes, even after reboot.
Im confused now.
Reviewing your initial screenshot, it appears the final two settings in the list needed modification for increased OCs. Therefore, "Short duration power limit" and "CPU Core current limit" were likely adjusted. Great news that another Prime95 version now runs smoothly. Still...as you mentioned, it's odd. 😊
Would you like to test a different CPU stress test such as Super PI to confirm?
