• Nice condition, warranty sticker, boxed
  • Resistance
    • VCore – 0.5Ω
    • VMem – 46.3Ω
    • PEX -93.6Ω
    • 1.8V – 910Ω
    • 5V – Ω
    • 3.3V – 33KΩ
    • 12V – 60KΩ+ (slot) 5KΩ (8 pin EXT)
  • Soft crashes on opening a benchmark or game, desktop can be re-accessed
  • MATS passes
  • Possibly fine, benchmarks all stable, on to desktop testing


Areas to take a look at are:

  • GPU-Z – TDP, Vcore volatage
  • Voltages before and during load
  • VCore phases using an oscilloscope
  • Test with clock-down core and memory
  • MODS – perhaps the memory fails at higher frequency

Update 20/10/2023 – More tests, no issues! Was there a driver issue previously on my test machine?

Well, I decided to have another look at this card expecting to have to tread carefully… However, this time I cannot find anything wrong with it!

Thermal throttling happens at about 82°C (hot spot up to 94°C), but this isn’t unusual for a cooler of this type. On to desktop testing to see if there is a sporadic fault.
