2600K OC troubles.

post #1 of 74
Thread Starter 
I've has this system up and running since January and it's been more or less stable. But, I'm still chasing down BSODs every 3 or 4 weeks and I'm not sure why. It's Prime stable, but it blue screens when I'm doing next to nothing. The last two I've gotten (both 0x1Es) happened when I was listening to music (nothing else) and watching something in VLC (again, nothing else). I'm at 4.5ghz and I'm already setting it for 1.34v in the BIOS (gives me 1.33ish in CPU-Z) and it's giving me 1.32v in CPU-Z under load (I've attached a screencap of CPU-Z with it under 100% load). I feel like that should be enough voltage. Yet I'm still having these nagging issues.

I guess I don't know where I should be at in terms of voltage with this kind of set up, I thought I was where I should be but... maybe not, I dunno.

Any suggestions or advice on this would be really appreciated.

1.32v sounds pretty low for 4.5Ghz overclock. Stable overclock for 4.7Ghz is average about 1.375v. Try upping your voltage to 1.34-1.35. 2600K is 4 core 8 threads, it's a lot tougher to get higher OC than a 2500K. You can disable the extra threads but it kind of defeats the purpose of having the 4c8t. Also having 8GB is still a bit rough on the IMC.

I needed 1.35v to be 24/7 stable, anything lower than that I'd BSOD after about 1-2 weeks.

Get BLUESCREENVIEW and tell us what is the error.

We're talking 1.35 @ load?


EDIT: The errors are STOP 0x1Es. So it's Vcore.

When you say 8gb is rough on the imc, is that directly correlated with core voltage? I know with p55 you would need to add more qpi/vtt/imc voltage when 8gb was installed. It seems with sandy bridge this is not the case. Would more core voltage be needed with 8gb of ram vs 4 gb of ram?

A small bump in vccio voltage helps counteract this in sandybridge 1.1v should do the trick

Would running the ram at 1333 be a little easier on the controller?
