I'm having a hard time finding 16gb dimms for this board that are on on tyan very short QVL list. If anyone can point me to some cheap ones that are known the work, I'd appreciate it, I do need 8 of them.
You could try some Samsung ones. I just recently put 8 x of my old bargain 32G modules in and they work fine even though they are 2400Mhz
Mine are M393A4K40BB1-CRC, 32GB, Dual Rank x4 PC4-19200T-R (DDR4-2400) Registered CAS-17
