Undervolting settings not staying | Bitcointalksearch.org

I'm so close to having my mine up and running nicely, but I'm having a slight little issue with keeping my undervolt settings consistent.

I'm currently running 6 x RX580s (soon to be 10, once I figure this out). My settings, fyi, is 1150/2000 with all voltages at 815. That gives me a steady 29.8Mhs, with my power at 110-115W per card, measured at the wall, and a temperature of 56-61C. Those figures all sound pretty good to me!

The problem is that while I have nodded the bios to those figures, every time I reboot, I have to manually set them in AMD Wattman, and if I don't, my power draw is about 150W per card, with a lower hash rate and higher temps.

So I'm a little confused as to what I'm doing wrong. I'd like to have this that if the rig reboots (as it did this evening), I don't have to waste time redoing all the voltages in wattman.

Any ideas?

TIA
