MLCC groupings can vary depending on the design and is not necessarily indicative of quality.” “Regarding partner board designs, our partners regularly customize their designs and we work closely with them in the process. Update: An Nvidia spokesperson told PCWorld the following: Most available GeForce RTX 3080 variants deploy MLCC capacitors in some form, and some people are seeing crashes even with those cards. To be clear, it’s not certain the POSCAP capacitors are the issue behind GeForce RTX 3080 crashing. Nvidia’s Founders Edition uses two MLCC capacitor arrays, and four POSCAPs. The five large black squares are POSCAPs or SP-CAPs the smaller array of white dots in the middle of the bottom row are MLCC capacitors. You can see the capacitors on the rear of the GPU on the fantastic MSI RTX 3080 Gaming X Trio above.
The cut-out reveals the capacitors on the back of the MSI RTX 3080 Gaming X Trio. I have one of those early review samples with six POSCAPs, and will be receiving the new version with MLCC as well. There were no 6 POSCAP production EVGA GeForce RTX 3080 FTW3 boards shipped.īut, due to the time crunch, some of the reviewers were sent a pre-production version with 6 POSCAP’s, we are working with those reviewers directly to replace their boards with production versions.ĮVGA GeForce RTX 3080 XC3 series with 5 POSCAPs + 10 MLCC solution is matched with the XC3 spec without issues.” It took almost a week of R&D effort to find the cause and reduce the POSCAPs to 4 and add 20 MLCC caps prior to shipping production boards, this is why the EVGA GeForce RTX 3080 FTW3 series was delayed at launch. “During our mass production QC testing we discovered a full 6 POSCAPs solution cannot pass the real world applications testing. Further testing by affected users seemed to reveal that the crashes happened in some games when their GPU boost clock speeds hit roughly 2GHz or above. Videocardz compiled a list of some of the reports from forums around the Internet. In the week after the GeForce RTX 3080’s launch, users began reporting that their graphics cards were crashing to the desktop when playing games.
Our original article below gets into the speculation, and we’ve also added a statement from Nvidia about the POSCAP vs. Nvidia didn’t specify what stability changes were made in the driver. The root cause of the crashing remains unknown. Read the details in “ Tested: Nvidia’s new drivers fix RTX 3080 crashes by sacrificing clock speed” and download the new drivers here. Update: We’ve tested Nvidia’s new Game Ready drivers and they fix the crashing issue, albeit by slightly dialing back the maximum GPU Boost clock speed in ultra-fast RTX 3080 models.
