Finally managed to get my rig up and running after having quite a lot of hassle with drivers and whatnot. I've got 6x 4gb RX 570's on ethash using claymore. Just wondered if these numbers seem ok for stock before I start tweaking... power at the wall: 750w hashrate: 24Mh/s gpu temp: 72 degrees c, although one is running at 68 fans are running between 20-30% - i'm surprised they're not running faster and it's a lot quieter than I expected? I've tried the blockchain drivers but they seem to give the same performance as the latest drivers. People seem to be reporting 20-30% improvements with the blockchain drivers or is that not the case any more? Also, i've flashed the c1.f6a mining bios (gigabyte z270p-d3) but it doesn't seem to have made much difference to numers or power consumption. I didn't get the "mining mode" option in the bios as per the gigabyte website, although it does say this is on the H110-D3A mobo only.
