Depends, if you have the LATEST Linpack library files it stresses harder than Prime95 because of AVX Instructions.

I noticed if manually setting all my Turbo Cores to all number like 47 would give me unstablity and preformance loss on folding and gaming.

May want to check it out.

let's say the system is stable at 1.35v. then i will have to set my vcore to manual, and it will always be 1.35v when idle and load???

I'm still finding it a toss-up. For checking FPU, Linpack testers with the AVX instruction set optimization on W7 SP1 are the best. But Prime95 has and still is extremely effective at testing all forms of calculations including FPU. Blend provides errors to me earlier in my testing so far.

It depends upon the LLC and the specific board. If I set 1.50000v (Bios) with LLC on Very High. Then I see 1.496v at idle (C-States disabled) and 1.472-1.480v at load.

With C-States enabled (and speedstep enabled), the chip will downclock to ~1600mhz and lower the vcore accordingly. At load though it should be the same as before.

Guys, I increase my DRAM from 1.5 to 1.55, failed blend test in 3 hours.

I increase the VCCIO, and it also failed in about 3 hours.

What else is wrong?

I'm getting BSOD 124

124, indicates more vcore.

I had the same situation, I would pass Linx, prime95 (small, large), but failed blend everytime. I increased vcore and now it's stable +18 h.
