I haven't found anyone brave enough to test a BIOS update for this card, at least not reporting back afterwards, so I was hoping someone here might offer their suggestions. It was bought used standalone. Originally from a Medion Erazer Engineer X10. I have never flashed a VBIOS before so I'm borderline clueless here.

This is what it reports as in GPU-Z: https://www.techpowerup.com/gpu-specs/zotac-rtx-3070-medion-erazer-oem.b9201

This is the sticker on the back:

And it looks like a Zotac RTX 3070 Twin Edge (Seller's pic, I have cleaned it after receiving it):

The current VBIOS is from 2020 so the lack of support is definitely from the VBIOS. I contacted Zotac's chat and while trying to help they didn't have information on it and couldn't guarantee it would work. The machine it's in at the moment doesn't have an integrated GPU so a failed flash would be really annoying.

Have you tried this ? : https://www.zotac.com/files/download/by_product?p_nid=959406&driver_type=238&os=All
Your card looks like standard Zotac card :)
 
Well if you can't afford to lose the card, even temporarily, then just avoid this? Rebar doesn't impact performance that much any way, low single digits at best.

Yeah, I was hoping someone would know if it really was just a standard Twin Edge, I'm not going to take a chance.
 
Buy cheap second hand gpu off ebay. Not more than a dollar plus postage
 
i would just not do it at all, there is little point in going through all that trouble, performance isn't worth it
 
Sometimes explorers need to venture and experiment even if there are no performance gains, experience is acquired.

Push the boat out! @Bjoolz
 
If it is a Twin Edge, the tool from Zotac should update it (almost) risk-free. If the BIOS file doesn't match it shouldn't proceed.
I know it because I updated the VBIOS on my 3070 Twin Edge OC on ZOTAC's recommendation.

I saw on the 3080 at least they removed or changed this because a lot of people were unable to update due to BIOS mismatch. Not sure if they just added a lot more versions it checks for or removed the check.

I went super cheap on my build this time, got a used PC with a 5700x and a tiny b550 board dirt cheap and it only has a single spare 1x slot which is basically underneath the GPU fans. So I would almost have to go for a USB VGA adapter.

Just enable resizable BAR in your MB BIOS settings. Flashing card is risky IMHO. Zero perceivable diff in gaming for me with BAR on.

Not enough. Early VBIOSes on Ampere cards weren't ReBAR enabled.
 
Until user gets a spare gpu, no point in trying to do anything
 
I have messaged some other users with the same GPU that tried finding the same answer on reddit and Medion's forum and if they reply back I'll post it here.
 
It has a custom subsystem ID, so any reflash would require bypassing the safety checks that could prevent flashing the wrong BIOS.

Do not do it until you have a backup plan
