Nvidia released the all-new 465.55 WHQL driver that provides stability for the RTX 3080 graphics card. It was strongly speculated that some non-reference RTX 3080 have stability issues, assumed this was due to the use of all six SP-CAPs (POSCAPs) used on some AIC partners. This prompted various manufacturers to respond and act in their own way- with EVGA and Gigabyte releasing official statements and MSI quietly changing its capacitor configuration.
Same issue with different AICs but different responses
Gigabyte did release a statement, saying that POSCAP being the culprit was false, and the newly rolled out Nvidia driver fixed the issue. Nvidia addressed the issue in its forum:
“NVIDIA posted a driver this morning that improves stability. Regarding partner board designs, our partners regularly customize their designs and we work closely with them in the process. The appropriate number of POSCAP vs. MLCC groupings can vary depending on the design and is not necessarily indicative of quality. “
Nvidia’s RTX 3080 Founders Edition also uses a combo of MLCC and POSCAPs but didn’t replicate the issue. Others did similar (except ASUS which used all MLCC array) but had different responses and action. Gigabyte, ZOTAC and maybe others had used all six POSCAPs which were the targetted group. But Nvidia’s response was also pretty vague at the time but the community provided the crowd-sourced test results. According to some Reddit posts, those with the affected RTX 3080 said that the new driver fixed the stability issue.
Lower voltage/ clock curve
HardwareLuxx also found a difference between the two drivers in the voltage/ clock curve. Though this was tested on the all-MLCC ASUS TUF Gaming RTX 3080 graphics card, it did show a lower curve with the updated driver. Clearly, the new driver addressed an issue wasn’t addressed in the GeForce 456.38 WHQL driver.
Along with fix, the update includes some minor updates. This includes official game-ready driver support for Star Wars: Squadrons. It also includes NVIDIA Reflex in Call of Duty: Warzone and Call of Duty: Modern Warfare. The new 465.55 WHQL GeForce driver can be downloaded from here. The relevant changelogs are as follows:
