Hi,
I have 6 x RX580 Nitro+ 8gb sapphire, I modded the bios and clocked the memory at 2250 and core at 1150.
All 6 are at 28 MH/s , but every few seconds I see at least one of the GPUs go down to 3-15 MH/s , then goes back up, and another GPU does the same. All GPUs go to lower hashrate at some point.
The temp is high 77-80C on some. Is it a heat issue? or is it a clocking issue? or something else?
Any idea will be very appreciated.
Thanks gents
