6900xt BIOS flash Issue

[Gonmun]

Hi folks,

So I've got a bit of a conundrum.

Last year I bought a used system from what I thought was a reputable guy as he's sold multiple systems in my area. I got a 7800x3d with a 6900xt Red Devil for a bit of cash and trade for a laptop I had. I noticed that I was getting game crashes unless I undervolted the GPU in Adrenaline but didn't think much on it until now as I hadn't gamed much on the pc as my son bought me a ps5.

I was thinking about going back and remembered the issue I had so, after some digging, I was reading that it would be good to check my vbios version in case it needed to be updated. Here's where things got weird. The bios read as 020.001.000.071.000000 which when I checked it out on techpowerup, says its a 6950xt bios. So, thinking that maybe the previous owner did something funky, I attempted to use the tool on techpowerup to flash it back to what I believed it to be. Unlocked the vbios, ran the utility, chose what I believed to be the correct version based on what it was identifying the device as, it said it flashed successfully. Then, it wouldn't. Stop. Booting. Until the system would go into a recovery mode. I wound up switching to the Silent bios and it has now booted but even that bios has the same version that was one the previous according to GPU-Z. I'm at a loss. I've done some more digging and I've noted the card has 3 power connectors instead of 2 so I'm almost thinking this is an Ultimate? But if that's the case, it's still the incorrect BIOS and it's ID'ing in GPU-Z as a 73bf instead of a 73af?

For reference, the gpuzcapoc image is what I'm seeing when I switch back to the OC bios from silent while the PC is on. The gpuzcap image is what my silent bios is registering for a bios. Both show it as a 73BF? But the picture of the card has 3 connectors like an ultimate which should be a 73AF?

6900 XT has two variants: original Navi 21 XTX (1002:73BF) and refresh Navi 21 XTXH (1002:73AF), used in the AMD reference "Liquid Cooled", and some high end AIBs like PowerColor Devil Ultimate or Sapphire Toxic Extreme. 6950 XT is Navi 21 KXTX (1002:73A5), this being just a third revision chip.

Since GPU-Z is reporting 73BF, that means this is a original 6900 XT with the N21 XTX core. Looks to be exactly this one:

PowerColor Red Devil RX 6900 XT Specs

AMD Navi 21, 2340 MHz, 5120 Cores, 320 TMUs, 128 ROPs, 16384 MB GDDR6, 2000 MHz, 256 bit

If it was not removed, then you can double check it by taking the card out and seeing if the identification sticker is still there.

The three types of 6900 XT are functionally about the same, revisions having just minor refinements over the course of production, and slightly more aggressive clock speeds. I wouldn't lose any sleep over it, Red Devil 6900 XT is about as good as a Navi 21 chip gets for most people anyway.

If that's the case then should I try and reflash the bios or just restore it to the backup and just continue to undervolt for stability sake?

It's so weird to me that it had a 6950xt bios on it.

Double check the sticker on the GPU and see what it says, if it matches, should be safe to flash the regular 6900 XT Red Devil BIOS onto it, which should in turn resolve all stability issues unless the hardware is damaged.

That was your first mistake, stop over thinking things. You should have asked here first prior to flashing a new Vbios.
