Hi all,

If I mine ETH only all works fine with a hashrate of 181MHs.
When I try to dual mine ETH+DCR (-dcri 30) I get 180MHs (ETH) + 5000MHs (DCR).

The problem is that while dual mining I got almost 1% of incorrect shares and looking the hashrate at poolsize I got under 170MHs (-6%).

Could someone help me to figure out where is the problem?

Thanks!!

Config?

EthDcrMiner64.exe -mport 3333 -epool eu2.ethermine.org:4444 -ewal myethwallet -epsw x -dpool dcr.coinmine.pl:2222 -dwal mydcrwallet -dpsw x

All the GPUs are RX580 8GB Hynix and are running at 1200/2250 with a custom strap and -125mv offset.

Some GPUs have a little amount of memmory errors but they aren't correlated with the incorrect shares (I got incorrect shares on GPUs with 0 errors).

The total power at the wall is 1150w dual mining and 900w mining ETH only.

This does not add up. In BIOS you have to set an exact value for voltage, but you say you use MSI AB style.
could you please share PBE screenshot.

False - edits with PBE trash are absolute, and work on few OSs, while offsets work globally.

I appologize but I did not understand your comment. Let me re-phrase my query.
I have RX 580.
I want to downvolt.
How do I do that?
Wattool does not work for RX580.
MSI Afterburner does work. But the maximum I can do is -96mv. Which gives me 0.931 For GPU core.
How do I apply -125mv. I can use PBE and apply voltage there but i have to use an exact value eg 900.

My question to "fjriosp" was to show how does he apply -125 with PBE?
