I havent even messed with linx as I know it will demand more voltage. Im focused on prime. I also dont think I have sp1 installed.

Dropped the ram to 1333 and its still failing at the lower voltages I had tried before below 1.4v.

@munaim1 will try your advice tomorrow.

I dunno if it matters at all but my chip is a happy camper at 4.7GHz @ 1.34, but requires 1.43v for 4.8GHz. You may have a similar chip.

Yah I've been pretty stuck on hitting 4.8

Probably a good idea to mess with 4.7

Same issue though today as yesterday. Booted up cold after work and I'm stuck at the window screen right before my desktop loads. Yesterday I enabled PLL overvolt which I thought fixed it. Today I rebooted and entered the bios, changed nothing exited and all was fine. Weird.

Set RAM manually to stock.
Try setting CPU current Capability to 140%.
Set PLL Voltage to Auto for now until you have got the CPU stable, then you can start lowering it.

Try those in a combination or seperatly and see if it makes a difference, I would certainly go back to the voltage that made the 4th core fail, it was 1.3625v right and then trying those above. That's all I have at the moment lol.

Hope that helps
I did all of this, same result. I think I have come to the conclusion that it needs 1.4v Oh well thats still pretty good.

For future refrence is anyone stumbles on this I ended up having the 4th core fail at 1.4v as well. That was the max voltage I wanted to go so I dropped to 1.375v and 4.7ghz and did 12 hours of prime blend.

I'm going to try to get that voltage down later but I'm happy with it for now.

I keep having one core fail when I try dropping below 1.35v @ 4.6GHz
post #30 of 33
I'm three hours into Prime95 blend @ 1.416v for 4.7 ghz. That's the best i'm going to do to keep temps under 75c for a 12 hr. run. I wouldn't be surprised if I dropped a core in the next nine hours, but I hope not.

I'll be down to 4.5 @ 1.3 for 24/7 use,tho.
