## ## ## ######## ######## Replacing E0 as per procedure Graphics Card VRAM Chip Replacement Procedure, I have Samsung k4G20325FD-FC03 in stock.
Nice, clear display, drivers load and MATS tests pass!
Next steps
- Despite my initial impression of the card being that it is good condition (has a backplate unlike my other reference GTX780s), I found that it had actually been opened, repasted badly, pads damaged, extra pads added wrongly and some wrong screws!
- I really need to find some correct spare screws from somewhere
- Replace the remaining thermal pads (just missing the VRM ones)
- Stress test the card
