In short: specific implementations with POSCAP design are suspected of creating instability specifically with a particularly high boost clock. That results in itself in-game driver crashes and the dreaded CTD (crash to desktop). The solve, reconfigure POSCAPs, add MLCCs.
One AIB has confirmed this:
Hi all,
Recently there has been some discussion about the EVGA GeForce RTX 3080 series. During our mass production QC testing we discovered a full 6 POSCAPs solution cannot pass the real world applications testing. 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. There were no 6 POSCAP production EVGA GeForce RTX 3080 FTW3 boards shipped.
But, 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.
EVGA GeForce RTX 3080 XC3 series with 5 POSCAPs + 10 MLCC solution is matched with the XC3 spec without issues.
Thanks
EVGA
Evga 話佢地一早發現有d問題
冇用晒6粒POSCAP, 而係同MLCC溝住黎用所以冇事
