Re: SRBMiner Cryptonight AMD GPU Miner V1.6.5

I have been doing some testing on one of my rigs before changing over all of them to SRB. The initial output I am getting is higher than what I have been getting with Cast, but I did notice something on one of my multi-card rigs. The hash rate started around 12.5k (with 6 cards) and then it dropped down to all except 2 of the cards doing below 2k each. I checked the temperature and everything was fine. I also didn't notice anything else strange. I stopped the miner and restarted it. They all came back to the normal numbers. Any idea what could have caused the issue?

try my settings for 2.1kh/s

overdrive p7: 1502mhz @ 950mv
p3 mem: 1100 @ 950mv
power target 50%
note: my cards are samsung memory

srb config is: { "id" : 0, "intensity" : 120, "worksize" : 8, "threads" : 2},

for each card.

this is vega 56 or 64? bios? and how much electricity use ? 950mv is to much.

vega 64.

950mv can be lowerd depending silicon lotery ;-p

i find 950mv the most stable with no stales or rejects and never any miner crash.

u can tune it depending ur cards and i would suggest to test each card with a lower voltage before putting them all lower than 950mv
