I have a pair of almost identical Z400s. (In total I have 4.) One has 4x 2 GB DIMMs (#3) and the other has 2x 8 GB DIMMs (#4) . Both have Quadro FX 1800 cards and trayless SATA bays. Both are connected to the monitor through an 8 port KVM switch.
Hipster 2020.10 was installed on system #3. The monitor was recognized and configured properly as 1600x1200 using the 340.108 driver. If I move the disk to #4 the nVIDIA driver didn't recognize the monitor or the resolution, set 1024x768 and would not allow me to set it to 1600x1200. I moved the KVM switch port for #4 to #3 and rebooted 2020.10 on #3. It behaves as expected, recognizes the Samsung Monitor and the correct resolution. After I installed the 2x 8 GB DIMMs S10 u8 kernel panicked on a null pointer dereference, so I moved the 2020.10 disk to system #4 and ran it for several days to see if fmd would log ECC errors on the DIMMs. fmdump -eV reports the log file is empty after 3 days. I don't know what whether fmd in u8 logs ECC errors as I've never seen any, though I have seen occasional ECC errors on system #2 which is running 2017.10 This morning I put the S10 u8 disks back in the system, booted and started scrubs at which point it immediately kernel panicked. I rebooted in single user mode. Both the root pool 3 way mirror and the RAIDZ1 export pool scrubs completed with no errors. The 3 disks forming the 2 pools were in a 6 DIMM slot Z400 (#1). That MB appears to have a failing SATA controller as it logged so many sector R/W errors it rebooted. I replaced the suspect disk with a new drive of the same make, model and vintage. The errors continued so I switched the u8 disks to #4. A subsequent test of the drive that was reported bad showed no errors after a 4 hr scan using the BIOS test. After verifying that 2020.10 worked properly in #3, I moved the disk back to #4. This time it came up at 960x540! I changed out the video with the card from #1 and again it came up in 960x540. I then moved the video card from #3 to #4. Again, 960x540. I reset the BIOS to factory defaults, changed the things (e.g AHCI) I knew had to be changed. Again. Same behavior. If I boot the 2020.10 Live Image on #3 it's 1600x1200. On #4 it's 1024x768. I tried the video card in the other PCIe slot. Same result. I'm completely baffled. I've never seen anything like this.
