i5 4690k overclocking issues

[jyrilutmanen]

Hi,

trying to overclock my i5 4690k processor with the system build below. However, every time I raise the clock frequency with more that 2% the computer freezes. Any ideas what the problem might be? Issues with the cooling of the processor or some kind of a weird power supply problem?

System build:

ASRock Z97 Pro4
i5 4690K
XFX 650 W Modular bronze
CoolerMaster Hyper 212 Evo
Radeon R9 280X
Corsair Vengence 16gb

Clock few? What are you changing the blck clock from it default of 100? If so dont just change the CPU multiplier and things like voltage don't bother with the blck

Yeah I was changing the blck when the computer froze immediately. I tried yesterday just changing the multiplier and that doesn't seem to cause the problem. Any idea why that works?

HWMonitor gave me however temps up to 99C°. Is it possible that the program gives me wrong temps or should I be worried?

Changing the multiplier is just how you overclock the CPU its much simple then fsb and other setting's


Also what CPU cooler are you using

I think altering blck affects everything including memory and possibly pcie - you just want to alter the cpu, pushing the entire system above what it's designed for can cause a lot more issues.
