Guys who have RX Vega56 how much hashes it give on cryptonight heavy algo ? and what power consumption i have 550W PSU
I think about buying 2 vega cards
With Cast or SRB, I get between 1330 to 1390, with a few peaks above 1400Hs, on 3 of Vega 56 reference cards. But they have the 64 BIOS.
I run the power table and Andrenalin drivers. Power consumption is between 140W to 160W at the wall.
So with 2 of them you should have 320W plus 80/100W of system stuff, total of 400/420W.
The 550W will do, although it may become a bit tight over time.
I changed GPU clock to 1490,907 and now I get 1540HS on the Vega 64 and 1415Hs on the Vega 56, run stable for more than 12 hours so far, using Cast.
Strangely the Wattage at the wall did not change at all, for 4 cards+ system it pulls about 720w.
