    Default Several RTX3080 custom boards see crash-to-desktop issues in games

    https://videocardz.com/newz/geforce-...ashes-in-games

    This now clearly widespread, but still unexplored issue appears in a certain group of games when the boost clock exceeds 2.0 GHz. As soon as the clock speeds reach a certain level, the game crashes to desktop.

    There is currently no official statement from any board partner, but ComputerBase has confirmed that they are in contact with the manufacturers. They were unable to reproduce this issue with at least three of the custom models they have.
    It could be an overclocking failure on factory-overclocked boards, but that should be easier to reproduce at the factory. It could be a software issue that should affect reference design boards as well.

    It could also be a voltage stability problem. Since we're seeing +12V voltage undershooting or swinging on a number of PSU models, when the +12V current spike heavily overloads the PSU and none of the power supply protections is triggered. If +12V voltage undershoots too much and system keeps running, the system may freeze or crash or display random screen.
    It's been a hard day's night and I've been working like a dog.

    Not the first time for nVidia. Saw this already with the first generation with GPU Boost, Kepler. Unstable graphics card because in the somewhat lighter games the GPU frequency boosted higher because there still was TDP and temp room for the GPU. However it seems that it affects more people this time.

    Interesting ... So if your GPU ends up being unstable, replacing one-two tantalum caps with multi-layer ceramics might fix it.

    Yep. You can't use tantalum caps in that application. There's an MLCC shortage. So someone probably just did a paper comparison and said, "this should work".

    No. No. This will not "work".

    AIBs and penny-pinching, what else is new?

    This new FE/AIB in parallel model that Nvidia is using now doesn't work for me. Too much margin of error.

    Back when I worked at BFG, all launch cards were reference. Once second source, cost down solutions, etc. were completely fleshed out, they would allow AIB's to "go virtual" with their own card designs/BOMs.

    If they had launched with FE cards first, and in parallel tested second source components for AIB's and then later went "virtual", we wouldn't see problems like this.

    Default EVGA confirmed the cap problem

    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 POSCAPís, 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.

    Also note that we have updated the product pictures at EVGA.com to reflect the production components that shipped to gamers and enthusiasts since day 1 of product launch.
    Once you receive the card you can compare for yourself, EVGA stands behind its products!

    Thanks

    This seems to be similar to the situation during the transient load of the PSU.
