How much does your card consume? measured at the wall?

same here - after the "april-update" from microsoft dropped from 2050-2070 hashes to about 1400 - tried to reinstall the drivers, use a newer version 1.0 of xmr etc. didnt find any solutions or workarounds yet...

edit: back to the old build - same speed 2050-2070hashes again...

I can't speak for everyone, but I can confirm that on my rigs, the Windows 10 update (which happened while we were traveling) definitely DID re-enable Crossfire on every Vega in our rigs. After editing the registry, reloading the drivers and running OverdriveN, all is back to normal on hashrate.

Just thought I'd mention it.

How to use --forcecompute and --maxmem for a single Vega56 ? I tried maxmem but it says that of I disable HBCC, i'd get upto 3% increase but if do disable HBCC, i get half the hashrate.

Also sometimes the miner just keeps showing hashrates and doesn't accept any share or new job.

Hey guys. I have recently build 8 VEGA rigs and using CastXMR. All is doing fine except yesterday one of my rigs went offline. Now when I tried to open de bat file it instantly shuts down the file again. I have reinstalled windows, adrenaline drivers etcetera but the problem persists. Im using exactly the same bat file (with another workername) as other rigs. Does anyone have idea whats happening here?

thats ccomplete bullshit...i have some of the red devil vegas too...they are ~20hs slower than my vegas with samsung memory...

you just need the right miner/overdriventool/powerplaytables config, thatzs it

Yeah I am using all of them, I can achieve 1900+ on Red Devil, but the rig is unstable - works few minuute to couple of hours and bye-bye...
I have tried cast-xmr, xmr-stack, srb, claymore...
Overdriventool, reg files (powerplay), bios flashes...
1050MHz memory is max before artefacts and 950MHz is max for continious work (1700-1750H/s) for Red Devil (Hynix).

Could you share your settings pls?

Check to make sure your copy of CastXMR.exe is still in the same directory. I had this a few times and windows defender had deleted or quarantined the file.

How can I optimize my miner ? Single MSI Vega 56 Air Boost (Hynix). Latest drivers.

Afterburner settings : PL : -7%
                              Core Clock : 1522 MHz
                          Memory Clock : 945 Mhz
                            Fan             : 74 %
               
                            temp           : 57-59 C
   
For SumoCoin (Cryptonight Heavy) I am getting 1350-1358 H/s but I am getting only 94% accepted with 3% "invalid result computation failed" and 2% "outdated because of job change"   after 24 hours. Is this normal ? If not please tell me how can I optimize more.
