Hi everyone,

So I’m helping a friend build a rig with 6 RX570’s (full specs below).
We got the whole thing up and running on windows 10 and all 6 cards recognised. Then we flashed the cards 1 by one using this rom that Anorak provided:
Anoraks_Gigabyte RX 570 4GB AORUS Samsung_memshift-A.rom (512 KB)

He said it should give 29-30 Mh/s but for some reason they won’t go over 25Mh/s using this rom. Tried flashing the bios myself straps 1500 and up but that gave max 24Mh/s.

Overclock in afterburner is core clock at 1280 and memory clock at 2000Mhz.

Using the mixed driver below and yes I have patched the cards afterwards. They are recognized by windows and afterburner.

Specs:
6x Gigabyte AORUS Radeon RX 570 4GB (samsung)
Motherboard: Asrock H81 Pro R2.0
Processor: Intel Celeron G1840
4GB ram
Driver we are using: https://mega.nz/#!JX51zaqJ!-X3u6G1pzuEFKICBM6C0O5tULzl4jtfWaVdkrzopHtc1

Really getting frustrated why it’s not going over the 25Mh/s when I see other people getting 27+ with the same card.
So does anyone know what could be causing this restriction? Please let us know
