Hello.
I just create a rig with 2
Sapphire Pulse RX 580 8GB with hynix memory, modified both cards with same mod bios. The hash rate i get is good 29-30 mhs per card. But they are getting too much energy. I don't know exactly how much W are getting from the way but in GPUZ they are getting much power. Dual mining ETH + DCR. The second strange think is that the first card is getting more worm with 81' Celsius. and the second with only 74' Celsius same config. In DCR they are getting 890-900 Mhs.
I try to under-volt with -72 in TriXX but the power stay the same.
Any advice?
Tomorrow i will try to get a power meter to know how much power they are getting from the wall.

C) I'd try to undervolt it even more. Some guys are running around with voltages as low as 850mv but most are around 900mv.
D) Get rid of Trixx. Get WattTool. I've tried ASUS GPU Tweak, Trixx, Afterburner, and WattMan...all of them are downright terrible. WattTool is the only thing that's truly worked when tuning my cards properly (YMMV). It does have more of a "you-better-know-what-you're-doing" interface though.
E) Dual-mining generates a lot more heat than single mining. At this point you have to ask yourself, is the extra heat really worth the DCR? That extra heat may seep into the section(s) of your house/warehouse to trigger the A/C to run more often, therefore eating into your DCR profit or even worse, eating into your DCR profit and ETH profit.
