I have seen that some persons here are using this boards, ASROCK C2550d4i and C2750d4i for their NAS solution. Me too.
These boards currently have a firmware bug which causes BMC flash memory to be written every time the watchdog is patted. Given enough time, the flash memory massively exceeds its rewrite capacity.
I have heard about this today the first time. I will install the new BMC version immediately.
More Details and a workaround to avoid this: https://forums.freenas.org/index.php?resources/how-to-avoid-dead-asrock-c2x50-d4i-boards-by-disabling-the-watchdog.16/
This bug has nothing to do with the LPC-Clock-Bug!
Asrock has currently released a new BMC firmware 00.30.00 which solves the watchdog bug.

I have posted this message already in the General forum, but this maybe the wrong one? Sorry for posting it a second time here in this board.
