I got a RTX 3080 20 GB from China, which probably has memory issues at higher temperatures. Repasting/repadding didn't resolve the issue. I don't want to reball the memory modules and so I am looking for a repair shop, which is located in the EU (for tax and shipping cost reasons).

It's really tough to find one. Krisfix.de was the only known good repair shop, but they decline to work on 3000 series since 2026.

Ask on mikrocontroller.net. There will definitely be people who know who in Germany is doing it or maybe even offer to do it for you. One of the last old fashioned forums on the net. German speaking but nowadays that shouldn't be a problem.

Curious, are they just generally not high-value enough any more to justify keeping spare parts around etc. for?

I see it listed on their pricing page still.

There are some pretty good shops in Bucharest, Romania if you are interested, a Friend of had problems with his cpu and it would crash, he sent it there and in 5 days max he got it back, he said it worked good now, and didnt complain about anything, but im sure they are not specialised in GPUs.
