Hi!
I'm trying to fix the mentioned graphic card.
Symptoms:
positive:
1. cards provides signal, actually I'm typing right now with this card.
2. I can reflash bios with nvflash64. I replaced bios with one from the TechPowerUp collection and behavior of the card didn't change. Used version of the bios was the same as the native one.
negative:
1. right after power on fans start spinning and stop. And I can't make them live (for cooling I'm using external fan). PWM signal on fans drops from 1 V at power on to just 0.4 V. MSI afterburner just doesn't see the card. The card is in riser and when the riser is disconnected from PCI-E bus, fans are spinning.
2. Driver installation goes normally but in the hardware manager window I see yellow warning sign.
3. Weird thing - may be it is normal for initialization but core voltage jumps up two times after power on, from 0.757V to 0.959 V and then remains at 0.757 V. And in thermal viewer I see that memory chips are switching off shortly one time at about 3rd second of power on. And exactly at this moment core voltage jumps up to 0.959 V. Voltage on vRAM is 1.37 V.
4. Reflowing of the GPU didn't help. Situation is the same.
5. Z-GPU attached.
Does it makes sense to reflow vRAM chips?
I would be appreciated for your suggestions.
