Help needed to identify RX470 4GB and proper bios

[Ravenscar]

I have a bunch of RX470's lying here, but I have no idea what brand the cards are and therefor no clue for the bios either. The logo on the card is unfamiliar to me.
The cards are all not working, no display, when I install them as secondary card, then Windows freezes once it tries to install the driver. I think the card may be flashed with a mining bios.

Based on the info I got through the amdvbflash tool, it has some similarities to this HIS card (not the looks though):

HIS RX 470 VBIOS

4 GB GDDR5, 1226 MHz GPU, 1750 MHz Memory

Anybody can point me in the right direction as for the brand of the card and the proper bios?

Many thanks, for any help you can give me.
Cheers,
William

The card with subsystem ID 148C appears to be from PowerColor, this BIOS, though unverified has the same RAM (Elpida BABG) in it, it should work. There is no verified BIOS with Elpida memory.
If it doesn't work, we can search some more.

Thank you for your reply!!
I will give that a try and report back here.

Gave it a try. Sadly not working as it should.
Instead of no display at all, the display is good before loading Windows/Linux.
It looks like once the driver is loaded the problems start now. In Linux just a striped grey screen, in Windows at first a good display, then when I tried to open Device Manager the screen went blue and flickering.
Do you think trying another bios could fix that?

Ahh, well might be the card is toast, but here are 5 more of all unverified BIOSes that are appropriate (Elpida-normal timings and frequencies).
1 2 3 4 5

Thanks again, I will look into those. The number in my first screenshot (in the prodcut name), I27210AI.HJC. How important is that? I saw the exact same product name on another Powercolor card, but that one had Hynix memory. I thought that I read somewhere that Elpida was taken over by Hynix. Could that be worth a try aswel? Maybe the software is not consequent about when to use Hynix/Elpida?
Just a thought, have not done this before, but trying to be useful too in the meantime.

Why not, worst case scenario you will see no changes. Most probably your GPU is impaired though.

Thanks, I will give it a go. I have 12 cards like this one, all with the same initial problem (no display), so I am still hoping it is "just" a mining bios.

Be sure to check subsytem ID's, they should be the same as in the BIOS on the card. I hope they work.

I have the first one working with the Hynix vbios... Dumb mistake from me though, all the cards look the same, the one I took apart had Elpida, the I had installed had Hynix...
But good learning moment, I will never forget to check each card now, even though they look the same.
Tested it with Unigine Heaven, which went well, only runs a little hot (88 degrees), but the fans are noisy so they may not work optimal. (already reapplied the cooling paste). There did not seem to be any thermal pads, but not sure if these cards come with those.

Thanks for all the help and pointing me in the right direction, been a great learning experience so far!
