Give it a try without the IPMI card as well. It could also be the obvious thing you’ve suggested and the coin batteries are dead (maybe the vendor had old stock?). Voltage on coin batteries can show normal without any current, then drop low as soon as there’s load. I’ve not replaced mine so can’t comment on removing any covering I’m afraid.

If you’ve tried two boards it’s probably some other part of the system. I few ideas- Could part of your case be bridging the reset pins (or some others?) Does the issue happen with only CPU + Memory (no PCI-e/SATA/Peripherals) attached? I’ve got the ATX board and the bios settings definitely don’t reset every boot.

I need a bit of help from my fellow W680-ACE owners! (ATX version) - I've been seeing an erratic issue where SATA link power management appears to cause random timeouts when an access is made to a connected HDD after an idle period. These are recorded as ATA errors in the `journalctl` log that look like: ata5.00: exception Emask 0x0 SAct 0x0 SErr 0x50000 action 0x6 frozen ata5: SError: { PHYRdyChg CommWake } ata5.00: failed command: FLUSH CACHE EXT ata5.00: cmd ea/00:00:00:00:00/00:00:00:00:00/a0 tag 12 res 40/00:ff:81:00:00/00:00:00:00:00/40 Emask 0x4 (timeout) ata5.00: status: { DRDY } ata5: hard resetting link ata5: SATA link up 6.0 Gbps (SStatus 133 SControl 300) ata5.00: configured for UDMA/133 ata5.00: retrying FLUSH 0xea Emask 0x4 ata5: EH complete Details: SATA link power management was enabled by: In the UEFI/BIOS settings: Storage PCH in AHCI mode (the default) "Aggressive LPM support" enabled All "Enable SATA link power management for hostX" options set to "Good" in `powertop` Note, you can't run `powertop --auto-tune` without freezing your system if you're using the onboard NICs as the drivers appear to be bugged. I have these disabled. HDDs: Model: ST16000NM001G (Exos X16 16TB) Tried connecting to both the SATA connectors and the SlimSAS Besides the link timeouts, there are no issues - SMART data is clear and full `badblocks` passes completed. PSU is a Corsair RM850x (2021) and is new. To do a quick check for historical link dropouts on your system, you can run: journalctl | grep 'failed command:' Investigation so far: Replaced SATA cables - Issue occurs Tried different SATA ports - Issue occurs Reduced to a single HDD - Issue occurs Connected an old Samsung HD103UJ HDD to the board - Could not reproduce the issue Connected one of the HDDs and the OS SSD and booted on my old Z97 system - Could not reproduce the issue I'm starting to suspect one of: My PCH/chipset is faulty There's a bug/incompatibility between the PCH/chipset and these particular HDDs There's a bug in the kernel's support for this PCH/chipset when SATA link power management is used. If anyone else is successfully using SATA link power management I'd be interested in whether you see this issue or not. Thanks in advance!
