3930K OC issue - Page 2

post #11 of 15
Thread Starter 
After further test i arrived at the conclusion (at least for 4.8Gigz) that the offset mod even with the LLC at max is unstable at the same voltage as the fixed mod
BUT if i add 50mv then i go to LLC High rather than extreme i could achieve a completely stable system with the same amount of voltage as the fixed mode.
That's very disappointing
Edit: i'll try for the 5GHz.
Edit2: didn't work.

from 4.5ghz to 5ghz the differences in gains (fps/score) is minimal

I know, i just do it for the fun wink.gif
So i think i cannot achieve a stable 5GHz with my cooling so i stick at 4.9GHz 1.46v with the offset mode biggrin.gif

I doubt this tongue.gif

Let's see the vcore at load.

1.5v/5ghz is petty standard for a truly stable OC on these from what I've read. If yours can do it at 1.36v you're probably the biggest silicon lottery winner ever on SB-E

On my 3820, 5ghz takes >1.52v (i won't go higher to check where it's actually stable)

So i think my cpu degrade a little bit
Bsod at stock setting i had to bump the llc to low rather than very low
And also add some mv to be stable.
