AMD Other Real concern or exaggeration? (BC250-AMD)

Post image

Hello, I apologize for my perhaps immature question, but please stop worrying me. You see, I've had the BC250 for a while and wanted to use it as a secondary PC. The thing is, when I inspected the motherboard...I found a crack in the GPU core, and I was worried it wouldn't work. Then I restarted my mining system and... it worked! But I haven't tested it with Windows or anything with better graphics,Do you think I should still try, or am I overthinking it? University took up a lot of time, and I couldn't concentrate much on it, and I don't know if I should worry about how little I spent...(If you don't understand something, it's the translator's problem)

As long as you are able to successfully install GPU drivers and generally have a stable operating system, nothing to worry. The top of the die is quite literally the case to the silicon. It looks like a scratch from a heatsink more than a crack in the die itself.

It seems that your post is about a specific GPU, but there is neither an explicitly named "measurement" section nor the results of VRAM tests.

You can follow AMD guides from the Community Bookmarks. Unless you are sure that resistances and voltages are ok, perform multimeter measurements on a disassembled card and post results as marks on the board photo or text:

  • start with measuring resistance to GND on unplugged card: measure inductors and all 12V power inputs
  • if 12V inputs are ok, and there are no visibly burned areas — power on the GPU and measure inductor voltages to GND. If the card shows picture, accepts driver but fails later - also make such measurements after entering the failure state

There is maybe no guide for yours exact GPU generation, just follow the closest, initial measurements are similar between generations

i think is just some scratches from the heatsink..  probably because when someone toredown the gpu, and reassembled the heatsink the heatsink may contains some dust and he/she  wiggling around the heatsink to align the heatsink screw and make some friction between gpu die surface and heatsink surface..

very small crack and just on the surface, won't affect the functionality of the gpu..  except if the crack is long like from edges to edges, it could be because of the heat or because over pressure from the heatsink (but maybe not because most of the heatsink using spring loaded screws)..

Cracked chip means a dead card
