SOLVED Only ~4GB RAM Available out of 128GB

[Dopamin3]

Edit: update from BIOS 5.10 to 6.40 fixed it


My system is in my signature. I just swapped out the memory from what was listed to 4 x 32GB Nemix Unbuffered ECC 2666MHz. I installed it and the BIOS recognizes it correctly, but in TrueNAS 12.0-U8 it's only showing 3.4GiB.

Some output from my system is in the code block below, but any ideas how to fix this? I'm going to try reseating the RAM I guess, but it detects it all both in TrueNAS and BIOS so I'm not confident that will fix it.:

Code:

root@RyzenNAS:~ # grep memory /var/run/dmesg.boot
real memory  = 137434759168 (131068 MB)
avail memory = 3491954688 (3330 MB)

root@RyzenNAS:~ # sysctl hw | egrep 'hw.(phys|user|real)'
hw.physmem: 3648987136
hw.usermem: 2746281984
hw.realmem: 137434759168

root@RyzenNAS:~ # dmidecode --type 17
# dmidecode 3.2
# SMBIOS entry point at 0x000f05e0
Found SMBIOS entry point in EFI, reading table from /dev/mem.
SMBIOS 3.0 present.
