jaffers Posted April 10, 2017 Share Posted April 10, 2017 So this gave me a bit of an undue headache because of a bad joint to ground, and I was wondering why nothing was working Runs an RT8867A, data sheet attached. Pull one of the purple points to ground (pin 6) with a 20k - 40k ohm pot. Do I even need to do the shunt mods? A quick run proved easy points on a $25 card running stock cooling, should be good under LN2 But I got beaten by 4ms if only I knew how to tweak gpu pi....

nachtfalke Posted June 5, 2017 Share Posted June 5, 2017 if you think to LN2 cooled card , need think also to do more mods ...FB mode is not enought ! you will kick OCP and OTP on this controller , pay attention to pin10 to manipulate the ocp and pin21/22 to pass OTP!
