240+ GPUs sitting in the storeroom, waiting to be dusted... that's a big effort to put humpty dumpty back all over again..... to be useful for just another 3-4 more months.
I just had to deep clean and repaste 160+ RX 470's. Took a bloody week and I didnt have the energy left to flash them and set them up. Its been two years ... I had forgotten how much work this was.
I actually stopped doing any thermal repasting work. I used to do that to my old Litecoin mining gpus like R9 270 and R9 280X and I noticed was that sometimes the old thermal paste is stuck on the GPU, and you need to give it a yank. All is well however I noticed that after a few weeks certain GPUs would stop working.
Only fix was to do the oven heat method where you cook the GPU in the oven for a few mins, it always fixed it temporarily. Which meant that the solder joints somehow got cracked and I think it was during the thermal repaste job. So I don't do it anymore since it hardly had a temperature effect anyways on the cards.
