Title: My first GPU miner got overclocked ! Post by: zoufou on September 16, 2017, 08:42:23 PM Hey all,
I finally managed to overclock/undervolt my 6 GPUs, i'm getting a 170 MH/s @1000Watts with the following configs:
Do you think i can do better at overclocking these cards ? am not sure how i can bring down power usage lower than 1k Watts ... Title: Re: My first GPU miner got overclocked !

Title: Re: My first GPU miner got overclocked ! Post by: Coinebauer on September 16, 2017, 09:16:48 PM How can each card pull 100 watts ("maxed to 100 watts") and your system 1000? Do you have a 400 watt CPU?

I don't have the info right now, but it's not a samsung one.Modded the bios with 2000, and set ethos "mem 2100" Title: Re: My first GPU miner got overclocked !

Yes, seems weird, my meter reports 1000W when the rig is mining, and ~90W when GPUs are stopped. And through ethos's /opt/ethos/sbin/ethos-readdata watts command: Quote 104.19 96.25 97.17 94.12 95.24 101.16 That means my 6 GPUs eat ~600Watts ... Title: Re: My first GPU miner got overclocked !

My 7 gpu saphire Rx 580 draws 780 watts at the wall (entire rig) so even tho the red devil's demand more power I think you could bring that rig down by alot. Also they hash 29.5 m/h each on ethash so to give you a basis to go by. All bios modded just with straps and using claymore for overclock/undervolt. Title: Re: My first GPU miner got overclocked !

Maybe that is comparable to the windows world's "GPU-only power draw", where all the memory consumption, board and VRM losses are to be added on top. That would make sense, since it's a good 40-50 watts per card on top. |
