ok i sorted the OCP on my card, i dont know what the max voltage i can run but its running 1.65 (1.63 under load) had to put the water block back on as temps shot to 90c instantly with the stock cooler but they are around 55c now on water.

to get past OCP with a pencil mod i shaded a few resistors, the 2 marked in the blue box and the one to the right of the smaller blue box.



R657 initial resistance 6 ohms - lowered to 4.3 ohms
R659 initial resistance 6 ohms - lowered to 4.3 ohms

R658 initial resistance 100 ohms - lowered to 46 ohms

off to do some testing
