Legit Reviews got their hands dirty this weekend with tweaking an RX Vega 64 LIquid and Claymore’s Dual Ethereum Miner. To push the 44MH/s you still need a lot of power with these Vega cards. However you can tweak a bit and get the power way down while not giving up as many hashes as you might think.



We took the Radeon RX Vega 64 Liquid model and lowered the power limit to see what would happen. Lowering it beyond 30% dropped Ethereum mining performance just slightly, but not by much. The power draw of the GPU decreased dramatically though and this is what we were after. At a -50% power limit we were stilling getting 37.6 MH/s of performance with the entire system pulling just 266 Watts. This is a 172W decrease in power consumption from the stock 0% power limit setting and the card itself was consuming roughly 172W instead of 344W. The cards Hashes per Watt went from 0.09 to 0.14, so this is a nice improvement in power efficiency without hurting ethereum mining performance too badly.
