MSI GTX 275 Lightning custom PCB

Recommended Posts

need ONLY  hard vmem mod for this card

for vgpu you also can use hard mode ( if i remember corectly is an uP6208 pwm controller)  , with FB at pin8 ...but you will enter deep into OCP/ovp protection and need to add VID mode to pass them , this i a bit complicated for you ... easy way is to use MadMatrix software witch is fully compatible from gtx285matrix with gtx275ligning ... tu use this need to run madmatrix.bat via administrator and change HEX value with voltage desired ...a DMM in real time monitoring voltage is highly recomanded , because some hex voltage value are different what you applied by soft and real one!

i can you help you wirh vmode for gddr if you provide me the pwm info!
