While I get that lot numbers matter somewhat, the variation seems quite high, but there are so many variables here to do a real apples to apples comparison, nervelessness I'm trying to understand any more details of your system and test runs.I'm not wanting to start a philosophical debate about IBT vs Prime95. I've made a decision for practical reasons to live with a stable IBT run of 20 standard passes, and if my games play, I'm satisfied. I just don't have the patience to run Prime95 for 24 hours.
Also, I've done Max runs with IBT but all I see happening there is to use all available RAM which is fine, but with 16GB, the test takes a longer to run with no discernible difference.
For reference purposes, my 4.9GHz setup has Vcore set to 1.488V and with LLC on Ultra, the Vcore will step up to 1.500V.
My chip can pass 24 hrs OCCT Linpack and 5 hrs of LinX set on "ALL" memory w with Vcore at 1.476v.
Takes 1.488v to pass 20 runs max of IBT with 16 GBs of ram (you know about this) but to pass IBT AVX needs no less than 1.500v Vcore with CPU/NB LLC on reg or auto (so far).
To make it through 24 hrs of Prime95 required same Vcore in bios (0.187500 offset = 1.500V) but needed CPU/NB LLC bumped up to "High"
I'm one of those that just has to pass em all to be stable OCCT, IBT, IBT AVX, LinX, Prime95 and Memtest. I'm sure this is why my voltage is slightly higher than most.
Most can't/don't take the time to pass Prime95
I too can run at 4917MHz with 1.488v Vcore with Dram kicked up to 2408MHz and both HT and CPU/NB Freqs at 2588MHz but not stable by my standards (not yet anyway). It does pass 5 runs on "Max" in IBT
This 4813MHz is by no means complete but I do sleep a little better being back in the "it passes the dreaded 24 hr P95" group. Now I can try lowering a few things to see if it will maintain current OC before moving forward.
Seems to have taken me forever to reach a point where it would prime for 24 hrs lol. For the longest time I never really thought it could!
