My 7GPU RX570 rig with flashed bios has 30.6MH per card with Claymore 11 under WIN10

30.6 Mh/s is impressive result for RX 570. Can you please tell me your GPU/Mem clock and what is the GPU temperature?

Actually I do not know exactly what the clock parameters are lol
I just flashed my cards with this bios
https://anorak.tech/t/sapphire-rx-570-nitro-oc-4gb-elpida/17038/10
Temperatures are excelent. Even while my rig is very compact so it fits in standard 19" rack.
Rig placed in room temperature around 22degrees C cards are between 63-73, depends on if I leave doors open to the room.
Rig placed in server room with ac, 54-64 degrees C

Lucky you

Max I can get from my ASUS RX 570 is 29 MH/s and even that is with some GPU errors.

To complicate matters, it all depends on the type of RAM your cards have too, which is luck of the draw when you buy them.
You'll get Hynix (best) 30-31Mh/s, Samsung (ok) 28-29Mh/s, or Micron (sucks) 28-29 Mh/s.

Is that the general expectation these days?
I always thought that if I got Samsung VRAM I was going to be able to do more. Hynix (formerly HYumdai electroNIX) is better?
I know that Elpida (now defunct, but owned by the generally accepted last place Micron), although some cards made 5 years ago have it, or does that brand live on, made by Micron?
I know that much of it is subjective, absent concrete measurements & data. My 6gb (Gigabyte) 1060 with Hynix is not keeping up with what the 3gb generic/HP 1060 which had Samsung memory.
I could OC the Samsung to +280 stable, but the Hynix has to be dialed back to +200 even though it will run with +240. I prefer to be able to leave my rig running for the week/end as opposed to having to constantly monitor from remote.

My RX 570 (Elpida) is stable up to 1950 MHz for memory and model with Hunyx is stable at around 2010 MHz.
