Hi All,

1st post so please go easy on me !

I have successfully managed to get a Monero miner up and running using 5 x Saphire RX580 Nitro+ 4GB Hynix memory.
Using all stock out of box settings they hash at 624 h/s

Im currently using ethos and using globalmem at 2160 and globalcor at 1215 with powertune set to 3, and globalfan set to 45, I have them hashing at 670 h/s running with the included sgminer-GM at 40 degrees.

My question is, is it worth me rebuilding the rig running windows to try and increase this hash rate? What sort of h/s do people think is achievable with these cards?

Currently my rig is pulling between 530 and 545 watts at the wall.

Any help greatly appreciated.

Pretty good stock hashrates... and very good wattage! Well my RX 480 has 840H/s with Samsung memory on XMR-STAK almost same RX 470 with Elpida. What is interesting that RX 470 with Samsung has 870H/s Cheesy

it could be alsmot 900H/s but it's not stable.
I will test hashrates with SGminer next week. SGminer should have little bit better hashrates, but I like XMR-STAK web stats.

You can use modded bios on ethos, only voltage in bios shouldn't be changed, but performance timings will work for sure.
You better use Windows for flashing card or usb flash drive with atiflash.

Another Happy Customer

Thanks Mattthev

Took a bit of messing around jumping from ethos to windows and back to ethos, but after applying Matthev's timings I am now looking stable with 5 RX 580 cards hashing Monero at 836h/s for 3 of them and 849h/s for the other 2. My fans are at 55% and temps are steady around 40 to 44 C. Power at the wall is now hovering between 694 and 702 watts.

I will report back in the morning.

Looking forward to the arrival of a replacement RX580 for a faulty one, and also the arrival of a couple of other RX 580's I managed to snaffle off ebay before they all vanished !

Thanks dgs2001

I was being a bit too ambitious, the rig stalled and stopped reporting after around 3 hours!

I have dialed it back a bit!
