A growing number of scattered reports identify crashes associated with factory-overclocked Nvidia GeForce RTX 3080 graphics cards. Tom’s Hardware has identified a statement from EVGA confirming that a particular type of capacitor could be a contributing factor to these crashes. A previous report by website Igor’s Lab stated that capacitors are the possible culprit behind crashes, instability, and black screens.
According to EVGA’s statement, when they found that a specific 6-capacitor configuration which “cannot pass the real-world applications testing”, the engineers were doing quality control on the new cards. Replacing some of the POSCAPS capacitors with a larger number of alternate MLCC capacitors fixed the problem. EVGA said, “This is why the EVGA GeForce RTX 3080 FTW3 series was delayed at launch”.
Rumors of problems with some RTX 3080 cards started circulating earlier this week, and now a growing number of reports have surfaced about forums and Reddit. As manually lowering the clock speed solved the problem, these issues were mostly seen on overclocked cards. Most of these cards use the whole POSCAP structure and the EVGA report seems to show that issues are common when their designs use the entire POSCAP construction.
“We do need to exercise caution, though. There’s still the outside chance that this issue isn’t entirely related to capacitors – Nvidia’s Ampere cards have higher power supply requirements than previous-gen cards, and drivers are still in the early stages of widespread use. As such, capacitor-induced crashes might not be responsible for all crashing issues – there are a lot of factors at play.” reads in Tom’s Hardware.
