(unstable/ maybe faulty) Sapphire AMD RX 7900 XT Reference GPU

Item is strictly sold as is, no returns.
23/8/26: Card has been used daily since beginning of July 2026 with no issues so far, there seems to be an occasional flash of gray on the lower half of the screen, similar to picture 10, but only on the bottom half for half a second when browsing the web

This GPU had issues back in June 2025 around when I bought it, I had repasted it with PTM7950 a week prior to this issue, it crashed and wouldn't POST and only showed a VGA light.

In February 2026, I tested the card and it worked again and well under GPU stress tests and had equal performance before comparing my screenshots on Cyberpunk and 3dmark scores
A few days later it froze and showed a gray screen with 4 vertical blue lines. And showed the same red VGA light as in June

More recently, in 2/7/26, I did a VRAM test and have been using it daily with no problems so far

It may work fine on another PC but I haven't tried it,

Attached are photos of the card reopened after I repasted it back in June 2025, it seems to be okay, no burn marks or anything.
2 missing non essential screws, see pics
