I'm running with the rig in the sig. Question about my overclock.
I'm running LLC at level 2 (Level 1 being no droop) and running at about 1.335v fixed vcore. At 4.7 this is rock solid and doesn't seem like a bad chip or overclock results.

That being said I would like to try for 4.8GHz 24/7 if I can. If I use fixed (or eventually go for offset voltage), what should be the max vcore I run through this thing for a "safe" 24/7 workload? I'm running custom water, so right now I have one core that peaks at 70c, the rest stay in the mid to low 60's at peak, low 60's high 50's average.

I should probably be okay with 4.7, but want some opinions. Thanks!

did you tried with no LLC? each level of LLC increase the total voltage at load even if the chip does not need it from 25% to 100%, try with no LLC and see if work.. about max voltage i would not go above 1.4v for 24/7 specially if you will be using fixed voltage. with offset you may toy with it up to 1.45v no more if you want to keep that chip a good long time...

I started with no LLC and slowly raised it up as I went through my stress testing and CPU multipliers. I did try 1.35v and Level 1 LLC and it wasn't stable so I was unsure if it would be safe to ratchet up the voltage at the highest LLC possible any higher.

I do plan to switch to offset mode soon to not keep my chip with high voltage all the time. That is, I will switch to offset mode once I find a stable fixed clock as a point of reference. I would like to keep the chip at least another year until Broadwell E shows up. I'm playing some CPU intensive games so the more frequency I can coax out the better.
