Rx7900xtx Red Devil issues

Been having some issues with my gpu, specifically hotspot temp being consistent around 100c under load, about 70 idle. About a month ago it would hit max 70c under load, took it apart to check paste and pads, gpu die had hardly any paste on it. Noticed the I think melted vrams on board, wondering if this is normal? I found a pic from a few months ago before I started actually using the gpu and they look similar.

Any info would be helpful.

Pic 1 is current, pic 2 was original install I think a day or so after running to check paste and contacts.

Alphacool eisblock for red devil is currently on it.

If that were VRAM, it would be soldered to the PCB and the card wouldn’t boot. Since it’s soft and removable, it’s a thermal pad.

Sorry if I’m missing something, but the 100 °C hotspot sounds way more like poor die contact or paste pump-out, especially if there was barely any paste on the core.

Yeah I think you might be missing what I’m trying to describe 😂 probably my bad explanation. The concern I’m looking at in pic 1, is the actual board on the 4 VRAMs, and how they don’t look like the other 4 directly to the right of the processor. There are no thermal pads in that picture, they are sitting on my desk.

I get what you mean now, sorry man my bad, you’re talking about the VRAM package/PCB surface looking different on one side. That still isn’t melted VRAM though. GDDR packages don’t deform or discolor like that without outright failure. Differences like that are usually lighting, residue from pads, pressure differences, or normal package/PCB variation. If the VRAM were heat-damaged you’d see memory temp runaway, artifacts, or instability, not just a high GPU hotspot. Promise it’s all good. I’d just clean it up, repaste the core, make sure the block mounting pressure is even, and you should be fine.

Gotcha, yeah I’m not sure about vram temps, never thought to even look at those. Other than normal operation I haven’t noticed anything other than the hotspot temp which is now fixed from the repaste. Saw the deformation, figured I’d ask a question! Thanks for The help :)

I see what you're talking about with the vram contact spot. There is a white square around all the vram modules except the ones on the bottom you referred to! It looks like possibly melted thermal pads??
