Topic: MSI Rx 570 8Gb Unknown Bios (Read 126 times)

I also posted this in the SRBPolaris v3.5 but got no attention.

Was wondering if amd/msi released new bios versions for the polaris series that are not recognized by SRBPolaris?
Are there any better bios editors that might get it right?

Weirdest thing just happened.

I picked up a few rx 570 8gb refurbished by MSI from newegg.
They look brand new with matching s/n boxes (not brown boxes)
When opening the bios in SRBPolaris V3.5 (same for V3.3) it reports "Bios is UNKNOWN, card may get damaged after flashing"
It shows the timings and everything but so far I can't get it to work with 1500> straps

I saved the stock bios with Atiflash_293 (maybe that is the culprit?)

With stock straps it hashes at 28.7mh/s in PhoenixMiner_5.3b (27-28 pool side) OC'd to cc:1170 and mc:2100 both on mV:850
No crashes and Phoenix reports a 68C temp with 108.4W power draw.
Wattman reports correctly the OC settings applied by OverdriveNTool

If I copy 1500 straps > then flash the new bios, pixel patch and OverdriveNtool I can't find a setting that works.
I tried every combination possible from cc 1100-1200 and mc from 1900-2100 and mV from 850-1000
As soon as Phoenix miner starts and applies the OC settings it either hangs or bsods.

Tried 3 different amd drivers. same outcome. currently on blockchain driver

I can provide the original bios if anyone can or wants to help investigate

I guess it's not terrible with stock hash. It's been about 2 years since I last did this so maybe I'm not up to date on things. I remember stock hashes on rx 570 used to be in the low 20s

Any help is greatly appreciated
