My plan for these are to try to OC them as far as possible from what voltage allows and actively cool the entire chip using a custom CNC'd heatsink or even waterblock. This entire project is just for shits and giggles and something todo in my spare time.
I assume there must be a spec sheet somewhere holding all this information that lists the maximum safe voltage for the chip before it dies. (Similar to what AMD and Intel releases with their processors)
So if you've got any valuable intel/documents, please share
