Hope everyone is making money on XMR -- all my 33 rigs are on Dwarfpool XMR.
Yup, XMR all the way.
My long term goal is move to all Linux for stability and further power savings (6x480 takes 1000watts on Windows, but only 730watts on Linux)
Please explain how you managed to save power using Linux when you can not do -mV drop.
the RX480s were originally mining ETH during ETH hey days
All my 65 x RX480s are modded with "29MH480LowEnergyOK.rom" from Heliox/Eliovp
Used the same cards on ZEC and XMR, in addition to ETH with no issues and still achieve good wattage.
Settings on Linux is at "stock" no settings in simplemining or ethOS.
Under windows you can lower power consumption considerably with Trixx or Afterburner. I'm trying to gauge how you come to the conclusion that Linux uses less power than Windows.
After the ROM mod, trying to attempt any finetuning in AB 4.2 or 4.3 will crash the rig or become unstable.
For 480 case, messing with wattman is no picnic too and I could only get 33% reduction in -mV.
But using the ROM mod as it is, can already achieve 29MHs, low power - just under 1000w for 6xGPUs and considerably less heat.
Putting this same rig but under Linux (ethOS or SM), kill-o-watt show 730w for the same rig.
Both systems if mining ETH with Claymore 7.4 Windows or Linux achieve same 29MHs per GPU.
Without ROM mod, and just -100mV or -96mV with AB, with 6xGPUs, just under 1200watts in Windows.
Did not try Linux at that time because I havent tried ethOS or SM or meddling with AMD drivers in Ubuntu was just too complicated for me.
Until this guy called Heliox got his Nanos modded and shared with members....
Yes, all my Nanos are also modded with Heliox rom mods but I could manage only the -100mV version in which was already a saving in power but could have done more.
My only GPUs that are not modded and yet the best performer currently are the MSI 390s - solid like a rock, finetuned with AB4.2 -96mV and OCed slightly, delivering 30MHs per GPU in ETH. Solid in XMR and ZEC too.
The only downside are 390s are power hoggers and all 5 rigs (5xGPU x 5 rigs) uses 1600w EVGA-G2s which cost me a fortune.
Thats why I am never going back that alley and stick to the 4-GPU Biostar Z170 gold standard like Phils for future builds.... unless Panda Miner becomes a reality.
