I haven't be able to get up to speed with the thread lately.

I am running two XMR rigs, 4 Vega 64 each. Windows Fall Creator's, August 23 blockchain drivers.
Total hashrate is 16060H/s (~2007 per card)
Using hellae's 1100MHz regedit (1407/900, 1100/905 probably)
xmr-stak-amd with 1932/1932 threads on each card
~1525watts from the wall (220v) with Corsair RM1000is

Is there any benefit switching to xmr-stak or cast-xmr?
Can I get any more efficiency out of them?

Thanks in advance!

I get XMR - Total Speed: 1682 H/s or something a bit over 1700. Not got the last part to 2000 yet, I dont find a higher core clock really helps me and I know it raises power usage a bit so I keep it around 1100mhz and memory same speed. I thought for 2000h/s I needed 1200mhz memory speed perhaps

has anyone encountered gpu compute errors for any of these reasons:

1) Too low memory voltage (like 900-925) on a vega
2) Vega 64 not handling 1100 mem overclock properly?

I am getting lost already, can't really find the sourse of the problem. Even at under 50C, I still get errors - probably on a single card, but cannot determine which one Sad

The memory voltage is just a floor figure to match the top voltage on the left there or so Ive read. I have it at 920 but in theory it might be possible to lower it further.
1100 should be fine, in GPU-Z it will list the SOC clock and it just has to stay below that. Try 1090
