my ambients are high... 1.392v would probably be stable

Are you tweaking anything else to get your voltage so low? I have to run like ~1.45 to get to 5.0ghz without HT on.

You are not alone, buddy. I have gone through close to 8 CPUs now and can't find any that runs above 5Ghz stable. I finally gave up and just sold my last 2600K. I'm on 2500K now. The heck with HT and the 1MB additional L3 cache on the 2600K.

Congrats...at least it runs stable for you. Vcore is a little too high for the speed, but not unimagineable.

Core volts I tried every increment from 1.5-1.63, and I still BSOD after 30 minutes or so between 1.55-1.63 no matter how high I raise the voltage, and even though temps are below 85 I don't want to push the volts any further. I've tried maxing out the LLC all the way to level 10 but still the same result. Any tips on how I can get it stable? Currently I have it at 4.8 with 1.48v and it is stable.
Go back to the F3h bios.
You'll be glad you did.
You will be able to lower your volts and lower your temps, too.
F3 final is VERY unstable. Erratically moving volts. And LLC10 actaully undervolts once you set the vcore past 1.55v.

Trust me.
Read the end of the UD7 thread on xtremesystems if you still don't believe me.

He's not the first.
A folder on hardOCP degraded his 5 ghz 1.5v chip after 2 months of folding, so bad that it won't do more than 4.6 ghz stable.

I'm telling you, all these torture tests at high vcore are not healthy for the chips. But no one believes me...just like in the Pentium 4 days..no one believed me then...until people's chips started dying. The chips would last longer if people just used high overclocks/vcores to game and bench, and not torture the chips with stress testers and folding constantly...

I mention OCN ..and not hardOCP
I was @ 5.1 1.49v for over two months (offset mode) ,degradation didn't occur
I'm at 4.7 now still on offset

P.S. folding for two months strait and benching are two different things
