Hey guys,

do you have any tipps which settings I could put into my Claymore Miner in order to reduce power cost?
For example reducing mvddc or cvddc? What would be a good setting for a 6x Sapphire 580 Nitro+ Rig?

Hi,
I am using both mvddc and cvddc in Claymore miner.
You should try -mvddc 900 -cvddc 900.
Let it run for a while, and if it's stable, then you can try lowering voltage, e.g. 875, until you find best settings.
You can also underclock each gpu seperate, e.g. -mvddc 900,880,910... -cvddc 875,890,910...
It doesn't mean that all gpu's are gonna run on same settings, even though it's the same brand and model.
I found this tutorial, it maybe helps you https://steemit.com/ethereummining/@nesahayward/eth-ethereum-mining-with-rx-580-8g-8gb-claymore-settings

You can also try OverdriveNtool for overclocking and undervolting.

Thanks! Im gonna use mvddc and cvddc in Claymore miner.. I´ve already set both to 900 and its working fine. Thinking about lowering it to 875. Should I go for both @ 875 or just -mvddc? I heard that changing one (I dont know which one it was) of them can be dangerous in terms of damaging the gpu...
