Hello, I recently had a problem with this one, when I bought it it came with the stock bios, and it is clearly capped at 405mhz because it is OEM, I had found a solution which was to change the bios to one that I found here at techpower which is this https://www.techpowerup.com/vgabios/200548/200548.

The thing is that it worked very well until now...

When I turned on the computer, the video card started to make very loud noises with the fans and not give video, and it only happened when I entered Windows, well in question I realized that it was the bios that I had put in (which I mentioned previously), since I changed it for another one and everything worked normally but with the MHZ cap,

I tried all the ones that were in techpower for that model, even the unverified ones

Has anyone had this problem that they could solve with another bios?

No. It is not capped at 405 MHz memory clock for any reason other than a fault or driver/software issue. There is no OEM firmware that just sucks so bad. That's crazy. Whatever the fault was, you tricked it with alternate firmware that pushed that limit out a bit, but now it is back.
When it is capped, what is the perfcap reason in GPUZ?

I would say a more accurate description is that you bought a faulty video card and need help figuring out what is faulty and how to fix it.

This is why it says it's limited, before, as I mentioned, it had an unofficial BIOS mod, which took the lid off, but now, out of nowhere, it stops working and goes into safe mode, setting fans to 100% and giving no video.
I bought it second-hand in 2020, I saw that many people had a problem with the mhz at 405, so what they did was use that BIOS that I installed previously, but as I mentioned it no longer works for me

GPU-z shows wrong VRAM bandwidth and doesn't recognise what GDDR5 exactly you have. I'd say it's 99.9% a hardware fault.

Get a fresh OS install if you have a spare drive (even live USB would do the trick) and if it behaves the same way you gotta pay a soldering iron a visit. Not sure if it's worth it to fix it, I'd try getting a refund if I were you.

He bought it used 5 years ago.
Not sure it qualifies for a "refund"
GPU-z shows it is running in 2D mode, try connecting a second monitor to force it into 3D mode, otherwise the card is failing.
I recall there used to be a thread on this 405MHz issue a while back but can't find it now.

It says it's in 3D mode when I hover over the frequency. Maybe the video card is already dead, but it seems strange to me because, as I mentioned earlier, everything was working fine with the BIOS I mentioned earlier...
Until I installed Windows 10 AtlasOS and it stopped working. It went into SAFEMODE (the fans were at 100% and there was no video).

Now I've gone back to normal Windows 11 without anything, and it still doesn't work.

And when I change the card's normal BIOS, the frequencies are capped at 405MHz.

All the solutions I've looked for all come with the same BIOS, which is the one mentioned above, but it no longer works for me :(

Things only last so long and the harder one pushes them, the quicker they wear out.
 
it's RIP
 
And something very funny happens: when I install Windows or enter safe mode, without any drivers, the video card works fine, without any problems, but when I try to install a driver, the problem starts. Only with the aforementioned BIOS, with the other layered ones, it doesn't happen.
And as I said before, it didn't happen.
I will have to use it with the normal bios, until I find one that works again

it is a dead GPU ticking time bomb mate, you had a good run but every symptom you mention is a dead GPU
