Hi - Can you please share how you got yours up & running? I just spent 3 hours trying to get my FEs mining. Whatever I tried, I could not get the FEs to "reset" (disable/enable) whether via device manager or via Wattman (tried on multiple separate clean DDU attempts).
The cards would disable OK, but upon re-enabling them, I got a "Graphics device driver error code 43". I could only get the FEs to reenable once if they were already disabled when I started my PC. They didn’t enable with the full memory available and only hashed at ~1400 h/s. I tired with my 64s and without. I tried with both FEs and a single FE. I have a Biostar BTC-250 mobo and all cards running off of riser cards.
I tried resetting cards (device manager & wattman approaches) at stock AND w/ a variety of custom reg files. No matter what, even stock, it crashed. The only thing I haven't tried is using non-blockchain drivers. My understanding is that the most current non-blockchain drivers are still not optimized for mining. Perhaps, I'm wrong and now the official, non-blockchain drivers, will get you to 2K+ h/s?
I also didn't try using any Vega 56 reg files but figured they wouldn't be mapped to the FE.
I'm using the same mobo and it works out of the box. I used the same steps as building any other vega rig and it works. Using Aug 23 blockchain drivers, overdrive tool to undervolt (min voltage is 950mv or so no matter what i set) and MSI AB to further undervolt (to 850mv).
My settings of 1400core/1100 mem/850mv gives 2100h/s. Lowering core to 1330 still give 2050h/s.
Did not use any registry mods at all.
What's so weird is that disabling and re enabling the card in device manager with the beta blockchain drivers and NO reg mods still give me the same device error. Are you on riser cards?
