This chip is D9TXS or MT58K256M32JA-100:A 

I have a feeling this isn’t going to be some routine memory replacement, all bits are failing in both chips, possibly some kind of power or memory controller (GPU) issue in the worst case.

Attempted replacement of E1:

  • Wasn’t easy to remove the chip, took several attempts and eventually 450 deg C hot air with pre-heater.
  • Replacement also seemed hard and I didn’t get it to the point of a ‘nudge test’ for fear of overheating. This is likely a mistake.
  • Trying a speculative test, as no short is present and the chip ‘appears’ to be on properly.
  • As expected, the test was not only unsuccessful, but MATS gave exactly the same report.
  • Need to regroup on this one I think and do some other measurements to try and work out if there is another issue. Hopefully some lessons will be learned even if the card never works..
