I have a question about the whole undervolting/bios modding/card optimising procedure.
I'm now at a stage building my rig where I'm installing the cards one-by-one, as seems to be the recommendation. I'm using 10 x RX580. While I understand most of the steps to the whole bios modding/optimising cards etc, I have a few questions. Any help is very much appreciated.
From what I can tell, on a basic level, the steps are:
1. Connect the 1st card to the mobo, fire up the machine.
2. Install drivers
3. Open mining software (in my case, it'll be claymore)
4. While mining, open Afterburner, GPU-Z, adjust core clock, memory clock, voltages to get things stable and more efficient (watch for hashrate drops, do small increments etc).
5. Flash custom BIOS to card (haven't checked to see if i've samsung or elpida, ubermix and anorak seem to be good bios's to use)
6. Repeat 3-5 for each extra card
What I'm a bit confused about is steps 4 and 5. Does flashing a different bios overwrite all those tweaks? And am I missing any other steps?
BTW, sources for my queries:
