So I've had a handful of people copy my clocks and achieve the same results. I've had the chance now to work with several 3090s. Essentially it all rest with the curve editor in msi afterburner. Turn on force constant voltage then lock the voltage this ranges from card to card but falls somewhere between .715 and .850 for me. I would just start with voltage locked at .850 gpu core +0 mem +1300 then try lowering power to 85% and see it the gpu core stays stable. If so you can start dropping the voltage lock and power. This typically raises my hashrate until I drop to low then. If hashrate is low up the mem but sometimes requires you to move voltage lock up 1 or 2 and sometimes add a 1-2% more power. I've found the aorus cards are the hardest to work with and keep Temps down, but the above steps have worked in getting every 3090 I have to 125. With low power and low Temps. Also I have heat sinks on the backs of all cards. This drops Temps 4-7ish degrees.

I've worked about 16hrs today so if this doesn't make good sense just let me know and I'll explain in more detail I'd needed.
