Re: Claymore's ZCash AMD GPU Miner v8.0

Does anyone have a experience running the XFX R9 295 X2? SOLs/settings/temps/watts/...

560 Sols total, 1100 core, 1500 mem, 72C and 68C temps, no idea about power, probably around 450W.

With those settings and default voltage it is more like 560w at the wall. It starts throttling at 75C, sometimes earlier depending on power limit.

Mine are in custom loop except one 'reference' model. It has default sapphire oc bios with 1030/1300, running it right now undervolted&clocked 886/1250 470s/s 360w at the wall. Voltage is 0.97V with AB -100mV, could be more efficient but needs more bios modding on that dpm2-5 area, been too lazy for that so far.

EDIT: 58 and 55C, ambient 27C.

What are the implications in the comparison of efficiency/functionality of the two Rigs:

A) 2 xfx R9 295X2 = ~$900 = ~1000W = 1120 SOLs

B) 6 RX 470s = ~$1100 = ~880W = 1120 SOLs

I think all of my presumptions are right. Is the xfx R9 295X2 similarly capable of mining ETH at the same ratio to the RX 470?

295x2 is good on density, easily over 1000 sols/s from two pcie slots, it looks and feels pro if that pump is silent. It is really good at xmr. About everything else speaks for 470.

470 is much more efficient on dagger. Sweet spot for 295x2 is ~52-54MH/ ~340w, 470 does much better. If you forget power costs then it is 295x2 all the way, used to run them ~65MH when one 295x2 made 20/ day.
