- Faulty or Leaking Electrolytic Capacitors
Some cards may contain faulty or leaking electrolytic capacitors, which can negatively impact system performance or stability. These capacitors may exhibit issues such as bulging, leaking, or even exploding, potentially damaging other components on the card. Users should inspect their capacitors regularly and replace any that are faulty or leaking to avoid damage or system instability.
- Bumpgate
These cards are likely to suffer a premature failure due to the defective 90nm process node from TSMC used back in the day, where the die underfill used was inappropriate for the chip design.
On Nvidia GPUs it mainly affects all 90/80/65 and some 55 nm GPUs (the A revisons of G9x and GT200 chips).
