Mattthev, Thanks... and a big thanks for all the work you do on this Thread and your BIOS mods, I wish i got your program PBE 2.2 last year... easy to use and dam they got my hashrate up even higher on all my RX GPUs compared to everything else i was doing before.
For everyone still tweaking BIOS, don't waste time like I did... use and pay for Matt's BIOS mods and/or his PBE 2.2 program with all the BIOS mods loaded in there, well worth it.
Question matt:
I'm using Wattman for OC and stuff, never used OverdriveTool... does it work better at locking in OC settings?
I have TWO RX570 Armor 4GB cards and when OC in Wattman the GPU clock still drops back to 950Mhz on its own, mem stays the same.. ?? changed risers, PSU is good as only 5gpus on 1200W Titanium PSU??
tks
Thanks.
Well, I've never really used Wattman so hard to tell

But Overdriventool is probably best option. You can control memory voltages in there I think in Wattman you can't. Also offset.
Have you also tried wipe drivers with DDU?
