RX580 Nitro+ 1 GPU slower / 6 GPU

[joboy84]

Hello,

I just switched my rig to zclassic

I have one card much slower than the others.



At the first start, it was GPU 1 who had only 153 H/s

I restarted the rig and now GPU 1 hashrate is ok, but GPU 0 hashrate dropped to the value from GPU 1 before the restart.

What can be the issue ? I see the temp of the first GPU is much lower than the others, but why ?

I never had a problem like this. Whan I am mining on other algorythms like cryptonight or ethash, all cards are mining at same hashrate. 

Thank you

had a similar problem, 6*RX570, but I had the issue with two of my crads.

I found out even they are basically identical the same bios mod might not work for all of them the same way.

So I had to change the bios mod for two of my cards, though if you never had a problem before with this might be something completely different.

cheers and good luck, i almost lost my sanity
