My RX 580 doing 31-32 MH/s

[Amstellodamois]

I'm a newbie, I started about a week ago but I thought it was my turn to bring some information to the forum.
I'm using Windows 10 fall whatever (1709?) and latest Adrenalin drivers in compute mode.
They all use Hynix memory, BIOS are one-click-moded via a fork of polaris bios editor.
5 of the cards are Saphire Pulce OC, the last one is an Aorus.

I've renamed AMD settings so it wouldn't load at startup. Rather, I'm loading profiles with OverdrveNTool.

Claymore's is only mining Ethereum, dcri is set to 10 (no idea what it does in single mode but it has a clear impact).


The six cards achieve over 191 MH/s together:

GPU 1, 4, 5, 6 use these settings:

GPU 2 these custom settings:

GPU 3 these:

Total consumption is a bit high  at nearly 950 watts, I'm still trying to see how low I can underclock everything.

Hope you'll find it useful.

Wow, great results other than high power consumption. I've only 1 RX580 also running @32 with micron the rest 570s running 30+/-. What memory are your GPUs?

[Amstellodamois]

I should have said that in the first post, I'll add it. It's Hynix.

As per my experiences I would lower the OC on that card that are generating memory errors, it will eventually get unstable and or provide less shares per hour compared to running 1MH/s lower.

Power usage is way high, you can do much better that, I have a 7 card 580 rig that runs at 910w at 213MH/s - But the real kings are the 570, most of mine are doing less than 110w from the wall, smallest one is 8GPU rig that uses 920w total for the entire rig, at 244MH/s total.

Nearly all 580's will run at 850mv at 1150 core, which is what im running my cards at.

have you test for 48H and you have no problem? invalid shares? shares rejected? Errors on GPU. I have the exact cards and i am able to get only 30.4 without errors. Too strange

30.4 is actually pretty good, im seeing between 30.3 - 30.6 on my RX580's - They are rock solid at those speeds, I can push them higher but then I start seeing invalid shares or driver crashes.

I believe it is better to have a little less hashes per second in exchange for just being able to set it up and let it run for weeks at the time.

Surprisingly, it has a pretty high impact on the hashrate. Going from 1230 to 1200 MHz makes me loose 0.5 MH/s per card with very low power difference.

Never had a rejected share. An invalid one a few times a day (not necessarily on the most OC card). Memory errors are on the right of the screen.

You will not see any difference in power usage unless you drop core voltages, but then again thats naturally up to you

If you are paying for power, you can get much better hashes per watt by lowering to 1150 and run at 850mv.

[Amstellodamois]

If you are paying for power, you can get much better hashes per watt by lowering to 1150 and run at 850mv.

But the drop in MH is higher than the drop in power.
In euros, not percent.

As per my tests im getting much better hashes per usd at 1150 at 850mv.

Each to its own though, it depends on your power cost and the specific setup, but you are using loads of power per card in this scenario which I honestly cannot think is beneficial unless you have very low power cost, seeing as you are listing things in EUR then you are most likely not on really low power costs.

[Amstellodamois]

Your settings make me loose 5 MH/s and save 50W. Even with expensive electricity ($0.19 a kWh) and today's shitty prices, it's (marginally, I agree) worth it to go for the extra power.

@OP Can you share the exact OC settings please?

Also the BIOS that you are using?

[Amstellodamois]

I did, they are on the OverdriveNTool window.

As for the BIOS, I let the the polaris patcher do its magic, I don't know if it copied lower values or created some original ones.

Can you link your one click mod you used?  My 580 gets only 26Mh after copying the 1750 strap up.

[Amstellodamois]

It's a Polaris....1.7.6 or something like that. Not hard to find.


Are you sure your cards are in compute mode?
Overclocked?
