Hello!
First post, starting with a question, of course. Sorry for that. But I am trying to, as the description of the post, to find out the values of a specific capacitor on my P102-100 GPUs (I have 3 of these with the exact same problem).
Long story short, bought several P102-100 10 GBs, Zotacs, from China. I tested a concept of a liquid cooled gpu mining rig, which has been mostly successful, except for these 3 ones. I forgot to add cooling bridge to the power-related (guessing regulators?) smd chips, and so after switching algos to quickly, the very same capacitors were blown on all 3 cards on the same locations. So my guess is that lack of cooling on these other smd caused some voltage spike or something.
Anyway, here is where I am hoping not to get to harshly judged. I have autism (as everybody else apparently) and I know there are better ways to invest time and money etc. And also I know its cheaper to buy new cards ("cheapest is to not do it at all") but I would like to attempt to repair them myself. Its a way of learning for me, and also, the mining rig, although not super profitable, has saved me a lot of cash in heating of the house during the winter.
The seller does not have any schematics, or bill of materials to the cards, and searching the web only gets me idiotic search results.
So the question: Does anyone have any idea if there is a circuit schematic, or PCB BOM, or anything similar that could potentially help me out?
If anyone interested in the results, I can mine full effect on ethash algorithms at 50 celcius degrees and under (ranging from 50 to 38 degrees celcius) per card and kawpows around 47-55 celcius.
As to the profitability, I mine diferent stuff, then use that to invest in other stuff with higher potential, more or less. Thats my justification.
Thanks in advance!
