hitting 100kh/s after some more fine tuning of clocks, hitting 2.78all core, set to 0.92v and 3.55 in oc tool. but reported voltage in ipmi is 0.88
powerdraw at socket 700w. vrm a few degrees hotter, def need those fans to get here!

ok, what are your bios settings ?? any cTDP and PPL/PPT limitations ?

how hot are your vrm's ?
is your mainboard installed in an open frame (mining frame) ??

high preset first then lowered voltage to 0.92/0.93 .1.05 gets out of control fast. change clocks. vrms 93ish nofan.
case in first post.
bios set a high tdp limit(dont think it mattered from auto, set it to like 300w+)

hooked up an elmoor evc2sx to the motherboard for direct voltage control and more accurate readings its also able to raise OCP on the vrm, but so far i haven't had any luck hitting higher speeds(temps are fine), there seems to be some other limit not allowing it to draw over 280a per cpu, i guess iam already pushing the limits of the mb, with only 2 eps 8pin plugs.
