New memory and new GPU. Probably some other small components too. Non-functioning DVI most likely leads to fried GPU.

There is a tool called "R5MEMID" that can apparently be used to diagnose bad memory on R500 based GPUs. I haven't tried it out myself yet, but I could give it a shot with my X1950GT AGP in the upcoming days. I suspect it works similar to R3MEMID. But it doesn't appear to need the -nocfg flag anymore.

If you're interested, I can attach it here in the thread.

In general, I agree on that one DVI not working leads to the GPU being under suspicion. Have you tried "the usual"?

• Let it warm up and check if the pattern / behavior changes?
• Check if applying pressure to any parts (memory ICs/coolers) changes the behavior?

The 1900XTX has all memory ICs on the front side of the board iirc, so checking that might be a bit tricky.

Did you perform a visual inspection of the card and/or would be willing to provide good, non glaring high res pictures so that a couple of folks may take a look at it here?

Cheers!

Card is a bit dirty, I'm probably going to remove the heatsink soon to inspect the memory/GPU die.

Probably fried GPU, nothing you can do about it. Of course you can always swap the chip but good luck with that 😀. That's the unfortunate fate of these high-end cards which push the tech to the limits. Mid-end cards are way to go.

The backside of the card looks like it has had seen quite some humidity. There are "clusters" of dirt around the VRM section, as well as some looks of corrosion around the screwholes. Could be, that the lighting is playing tricks on me here. But I'd say this card has earned a proper and careful cleaning with some isoprop + toothbrush.

The broken inductor in the bottom right is not nice, but probably not too bad for now.

I might have "fixed it". I removed the entire blower/heatsink assembly and left it on the POST screen for about a minute or so. Gently pushed on the core/vram with the non-conductive base of a screwdriver. Rebooted the system and that corrupted screen from the 1st picture is completely normal. Both DVI ports magically work as well. I'm going to see if it starts correctly from a cold boot.

Yeah, this is why I'm probably going to stick with my Geforce 7900 GS. That card runs silent, even under full load. My WD Black HDD is louder 🤣.
