your numbers are off - in my opinion.



I have four 1080TI and I've spent a lot of time tweaking them. I don't see 40Mhs on any of them. Low to mid 30's at about 70% power usage is more accurate. If you know how to get better - I'm all ears on the settings you recommend. Right now I'm using ~ 70-75% power target, ~1800Mhz core, 2000Mhz memory and that puts me at low-mid 30MH/s - in the neighborhood of 165-190 watts per card.



I haven't mined with Vega, but my cousin is mining with two Vega 64. He doesn't have a way to measure power use, but he is at -25% power target through AMD Wattman and consistently mining at 37-38Mh/s per card. He has nine 1080TI and he prefers the two Vega 64 for mining as it is $100-$200 cheaper initially, and so far as he's getting a better hash rate without any optimization to memory straps or firmware ---- except to use the AMD beta mining drivers. He plans to start buying Vega 56 when they come out for mining.



Like I said he can't determine power use yet - but he uses similar settings to me on the 1080TI. I told him to buy a P3 kill-a-watt to determine something to see the discrepancy - but it's not like the 1080TI are just sipping power. He has his 1080TI set to about 165 watt per card at 65% power use.







By the way, I have two PNY 1080TI reference blower card style, and two EVGA 1080TI SC cards. The EVGA cards don't like to undervolt well. I can take the PNY all the way down to 50% power target. I can't go much below 75% on the EVGA. They seem to have built in overclocking that requires some extra power. But the EVGA ICX heatsink is much better and the cards run cooler to be sure.
