    Hi,

    I am having a hard time with my voltage setup on my second rig so any help would be great, I have the below setup.

    Asrock H81 BTC Pro R2.0
    6 x Sapphire RX480 Nitro+ 8GB
    2 x EVGA 750 G2 PSU

    All bios mods are running Ubermix 3.1 via PBE 1.6.4

    It currently runs cards at 1100/2000 875/850 & a couple at 1050/2000 850/850

    I am getting between 29.2MH/s & 29.5MH/s per card total of 175.5MH/s for entire rig.

    Running WIN10PROx64, Claymore 10.1, using DAGFIX drivers mining ETH only, but it is pulling over 900w at the wall, using Wattman to control speeds etc. (Temps range from 57-62)

    My rigs run relatively quiet, due to their locations, quiet enough the wife is happy to have them in the room and quiet enough you can hold a conversation next to them (Saves me having to turn on the heating)

    I had this running at just under 800w a few weeks ago, but unable to reproduce how I did this, so any help would be great





    Managed to reset everything and start again, now pulling 840w-845w.  alot better than the 960w it was pulling. And managed to squeeze out another 1MH/s and lower temps a degree or 2


    Not sure what happened overnight, but woke up to the rig going nuts, pulling 1150w, killed miner and restarted, now pulling 765w - 770w WTF?

    After a reboot its now pulling 900w - 920w erratically.

    Anyone have any ideas?? its getting frustrating, it can run for weeks stable as hell and poof overnight, no changes it just decides to throw a wobbly.

    My 7x RX470 rig has been running for months no issues (fingers crossed), so solid. But the RX480 rig, same OS, same CM, Same Drivers, Same PSU's etc does not.
