I have lowered from 2186 to 2132 on my 580 8gb micron rigs almost while moving to 832 the voltage.
Non perfect but it works stable with version 1.2.3 if I remember correctly
On the test rigs with 3 elpida 570 pulse 4gb I simply reinstalled my original bios WITHOUT the new straps and set the same value I had before (subtrack 24) and I'm getting 1970 mh/s with neoscrypt, so not bad.
I need to restart the rig once a day as Cpu utilization tend to increase.
Neoscrypt only for both rigs.
You wrote that also criptonight can be a good choice for AMD, but I haven't find a good coin to mine that generate the same profit as ETH.
If you can, please hint me on that.Tx
Today eth is most profitable on AMD. But week ago for a long time cryptonight was very profitable on many coins.
With bitcoin drop all cryptonight coins drops too.
On last version CPU usage grow is fixed and now it's not need to restart rigs...
