Now the light is a little better, the controllers are AJ-AA 20P and AP-AA FOW

Hey Kenny, did some searching in my inbox and found a convo between us and found this: http://i.imgur.com/J7MMD.jpg
whats on the other side of teh PCB from those controllers?
- looks like those are handling 1x phase each for GPUv? ... is there no master IC?
*I make out RT IC at bottom of pic.. most likely for mem.
Those 'AJ' and AP look like BN controller off of Alpha dog 8800GT
its just a hunch by looking at the design.. but i would say the IC at U507 is the master... and the one at U508 is a slave. One IC for each phase...
*what do you see with DMM at R16, R17 and R122 and R123... any 'good' resistance levels and continuity?
try to lower R16... from the other mods i have done using these stupid IC's.. GPUv resistance was right at 1k.. VR = 20k
*like this one... alpha dog 8800GT ... FB pin is top-side.. outer-right pin.. never could find DS for it
