Iam now trying to get max stable Point for every single Card. Vega56@65 Air Bios with reg from RednoW. Is it normal that every Change in OverdriveNTool to Voltage Settings results in a mem reset to 800mhz? What iam doing wrong?
I don't know what exactly you are doing. My mod is for vega64 liquid bios and the only steps I do on OverdriveNtool I described earlier.
Are you using Air Cooled GPUs or watercooled? Your Settings run for about 10min at 2k Hashrate and then Windows freezes. I have a strange Feeling flashing 64 LC Bios to 56 AC Card

I'm using vega56 air with vega64lc bios without any problems. One thing - all my vega56 are sapphire from one batch ... maybe other v56 can work not so good.
But I helped some persons (that was my greedy 0.4eth payed consultations) with v56 too and nobody complain ))
