As a person earlier mentioned to try higher i did.

I just recently for a semi stable overclock at 4.4 with a vcore of 1.4v, any lower and it would bsod instantly.

I changed the ram voltage from 1.5 up to 1.64 with a clock of 4.4 and it would still run the test for a couple of mins without blue screening at all.

Sorry if I'm not making much sense, kinda new to over clocking.

Ok, it's not RAM voltage then, more likely to be timings. Are you certain the RAM is running the correct timings according to its rating? Check for XMP also, if it supports it I do recommend enabling XMP.

I think they may be wrong.

Thought I would flash my bios to f10 and turns out it disabled my USB ports and I can't seem to find my ps2 to USB adapter.

Once I get this issue fixed I will get back to you on how that goes

 

Check for XMP also, if it supports it I do recommend enabling XMP.

 

Yes this.... this is what allowed me to get to 4.4GHz on my 2500k... My CPU is apparently not a great OCer... and the easiest way I was able to get to 4.4Ghz was to set XMP profile in BIOS for the ram, and select auto vcore and simply change multiplier to 44x. the Vcore is a little high on auto (1.344v) but auto is the only way it would be stable.

 

Just to clarify... reset BIOS back to defaults... and don't change anything but the stuff above^^ - 44x might not be for yours... just try starting at 40x and check temps and vcore as you increase the multiplier.

Thanks for the info I will try that

I got it stable at 4.2 finally but voltages are a bit high.

When you say your cpu is not a great overclocker, I have heard two of the same builds could run differently and one better than the other, like a car I guess. Is that purely just the CPU that won't allow the overclock as high as another or is it a combination of both CPU and mobo?

Reason I ask is if its just the CPU maybe I might invest in a new one

 

Thanks

It could also be the motherboard... whats the vcore @ 4.2GHz?

1.4v.. Going to try and test going lower, when I tried the other night it was not stable, but will try playin with other voltages to get it down

Temps only run at 55 when stress testing at that vcore
