Good day.
I have 3090 FTW3 ultra rev 0.1 card + waterblock + additional power to pcie slot on motherboard. Won't RMA my 3090 (another country, ages to ship etc...).
With bios from 1st post in ths thread i get max. power draw around 450watts. Rebar is enabled.
I tried 1000w kp bios (with rebar support), powerlimit 52-54%, max. power draw is around 520-530. In Port Royal and fire strike ultra gpu clock speeds are stable. But rebar isn't enabling, eth mining doesn't work. I tried modifed 520w kp bios (with rebar support), max. power draw is around 460-470, rebar isn't enabling, hash rate is slightly lower than on stock bios.
Is it possible with rev 0.1 card to get max power draw around 490-500 watt with working rebar and working eth mining?
reBar does work if you flash the newer 1kw bios,

When you do this it will mine in P0 state. This will actually give a slightly higher hashrate with the same OC, but may be less stable too. This is why most of the time you can mine at a higher mem OC than you can game.
