I updated my rig now. Swapped 4 Vega 64 with 4 Vega 56.
Running with Amd Driver 17.9.1
Vega 56 flashed with 64 bios
Samsung memory on my cards
Mining Musicoin (Ethash)
Claymore config general settings:
-tt 64
-ttdcr 75
-cclock 1000
-cvddc 900
-mclock 1025
-mvddc 900
Getting steady 41,3 MH/s per card.
130 watts per GPU at the wall. Mobo, CPU, etc already accounted for.
With dual mining it drops to 38 MH/s per card and fairly low stats for the other coin, so I'm skipping dual mining for flashed Vega 56.
I'm using the excess heat from my mining rigs to heat up my appartment, so in my case there isn't much cost involved with electricity during cold seasons
I have two Vega 64 cards now, same settings same everything. One is capable of 1250 H/s on Monero, the second one can go to 1580 H/s o.O
Would you mind sharing your settings?
After a reboot, I am not able to reproduce the 1580 H/s score
Both cards run between 1250 and 1280 H/s. Just standard Wattman settings, core as low as possible, mem to 1100, temp limit 71℃, -5% power. However, this is not enough to reduce the power draw at the wall.
We need to give rednoW some motivation to share his guide with us. A kiss won't be enough I assume.
To get back 1600h/s xmr stop your miner, go to radeon settins, gaming and move HBCC slider slightly, then hit apply.
Then run you miner again, here you go again ))
Need your kisses ))
These two posts combined are some sort of black magic.
Running 4xVega 64 @ 1550H Monero mining @ 930W total system draw.
The trick to moving the HBCC slider was true. All cards 1200 before. Moved the slider up one notch on each card and hit apply one at a time. Now 1550.
At around 60% fan speed each card is going no higher than 65C.
These same settings yield 41 MH ETH mining but at much higher power draw (1200W).
