ASUS STRIX GTX 970 DirectCU II OC (Card D)

Seller Note “Works fine until under heavy load, then crashes”

Summary

  • Resistances (TODO, no shorts)
    • Vcore –
    • Vmem –
    • PEX –
    • 5V – 3.7K
    • 3.3V – 768
    • PCI (slot) – 5.7K, PCI-E -KOhm++
  • The card reaches windows, but crashes on driver load
  • Next Steps
    • Confirm memory is OK (more suspect a VRM issue, but could be wrong)
    • If VRAM is OK, complete resistance measurements and investigate phases using an oscilloscope
    • Possible phase issue moving from idle to run state, insufficient power from VRM?
