Good Day.

I have a amd rx 6900 xt refference model. as soon as the i turn on the pc and it posts but when loading windows it runs into blue screen of death and its doing it intoa loop..it gives driver verifier dma violation error. any idea what could be wrong.

i have tested the card while in operation and all voltages are ok within normal range. Any help is welcme.

Cheers

In most cases when you have good resistances and good voltages there could be a problem with four RAM chips located at the bottom near te PCIe slot. Pads are very often ripped off under them because of bending of a PCB.
The first suspect is the third RAM memory counting from the left on the PCIe slot. Unsolder, inspect, reball or replace memory. Maybe a pad is ripped off from the PCB.

Did the memory test show errors?
Does Windows start without a driver?
