Hi

I have followed both instructions and saw that I can get 28Mh/s! Totally appreciate  your help!!

However I notice something which may need advice if it is common.

My GPU 2,3 and 4 runs higher hashrate about 28+Mh/s quite regulaly. GPU 0,1 and 5 often ges to 25-26Mh/s. Is this normal?

Also I notice that sometimes when a new "job" comes in, the speed varies greatly.

Sorry I am quite new to this. Thanks in advance!!


Not all GPUs overclock the same way. You may need to expirment a little more with those GPUs, sometimes decreasing or increase both core or memory clock. Its all about trial and error until you find the sweet spot of your GPU.
Noted Smiley Thanks!

all of them red devil?
maybe the slower gpus have hynix memory, if its hynix then you need to clock the memory higher to get good hashrate.

Yes sir, all red devils Tongue

I may have my timings wrong because its still relatively low after OC hmm..

That is way too much overclock and you will ruin your cards that way. My RX 470/570s run 28MH well at 1050/2010. Been mining ETH stable since last year.

Also just mod your BIOS first. There are a lot of guides available online and you don't need to download one from other people. Google is your friend.

Many thanks for your advise. I will check out it very shortly!!

Hi everyone,

I have 6GPUs from RED DEVIL RX 570 4GB (Samsung) the problem I face is that the hashrate per card will start about 28Mh/s and subsequeny drop to 15Mh/s to 20Mh/s.

I have overclocked using MSI AF to 1467/2250 but it is still the same.

I have yet modified my bios as I can’t seem to find mods for Samsung.

Can anyone point me in the right direction?

Thanks in advance

ori0n.
