I have an 8 card rig getting 8k/s total.

5- MSI RX470 8GB mining edition
3- Nitro RX570 4GB

Im getting 980 h/s from the 470s and 1k/s from the 570s but at 125 watts per card. Total rig power at the wall is 1000watts. Is there any way I van lower the power draw???

Hi! I daresay this miner is the most power efficient miner for all the variants we support. The tools at your disposal are bios and clocks tweaks. There are other people here that have trimmed their Polaris rigs much more than I have, hopefully then can pitch in.

As a start, can you tell us a little more about your setup? What clocks do you run the cards at currently?

I have the RX570s at 1250/900 core 2050/900 mem and the RX470s at 1250/900 core andcore. 0/900 mem. Even lower settings it doest save much energy at all. I have them modded with the pimp my straps mod. And Im using the blockchain drivers.

Hey, when I first tried this miner (v8) I have read the readme guide, this miner needs bit higher undervolt (windowa 10 here), but unlike other mines, even 1150 mhz core gives you still near max speed. I think you have an issue with speeds, see when core increasing starts to give deminishing returns.... going from 1150 to 1250 for +30 h/s is so inoptimum. I wouldn't use 8gb ever to mine monero. Bittubev2 and heavy variants, speed is 1200+ with proper timings and 1250 core. The 4gb is surely fine. Notice 8gb filled of gddr5 filled with data conaumes more than 4gb.. so I would use those for an algo that rewards (most heavy variants) and keep 4gb 570 to monero. (560 2gbs I found even more efficient, more than vega if for one reason)
