PCIe correctable errors

Hardware ZimaBoard
1

I’m having issues with my Glotrends PA20 card (which I think is the same card that IceWhale sells directly?). My logs in Unraid show quite a few “correctable” errors. I’m using the Zimaboard 2 1664, with the NAS kit and riser cable. Plugging the card directly into the Zimaboard does reduce the errors slightly, but still occur. I’ve also tried cleaning the contacts, etc. PCIe ASPM is disabled in the bios. Anything to worry about? Anybody else see these errors in the logs?

Hey, yeah this one comes up a bit with these setups.

“Correctable” errors basically mean PCIe is fixing the issue on the fly, so not dangerous on their own.

The key clue is what you already saw:

  • fewer errors when plugged directly
    → that points to riser / signal quality, not the card itself

With ZimaBoard + riser + NAS kit, it’s pretty common. You’re kind of at the edge of what the PCIe link can handle cleanly.

If the system is stable, I wouldn’t stress.

If it’s spamming logs or causing issues, then it’s worth:

  • reseating everything
  • or dropping PCIe speed (Gen2 if BIOS allows)

Otherwise, pretty normal behaviour for this kind of setup
