I’m doing a RAM upgrade on my TS440 and I’m running into some issues.
I have 4x8GB sticks and they are all known to work and be compatible with this motherboard (I tested them all one by one and by sticking them in my TS140 which is basically the same machine in a different form factor case (32GB detected success)).

It seems like there is something wrong with DIMM1 and/or DIMM2. I don’t see any obvious physical damage to the motherboard.
Update: It seems booting with this ram is unreliable even on my TS140. I run into kernel panic errors when trying to boot TrueNAS when I have all 32GB installed. And then when I restart it won’t POST with no indication of failure. Just black screen and fans running. I have to remove all but one stick in DIMM0 to even get to the BIOS menu.
It looks like I can only have two DIMM slots filled at a time, so I am currently running Memtest86 on two sticks and then tomorrow morning I’ll test the other two. I suspect I may have bought some DOA RAM. The ebay listing was suspiciously cheap.
