Ohhh ok. I understand. Then it looks to me like both the Tyan and the SuperMicro use the same style DDR3 UDIMMs, just X9SCM also supports 1.35V.
So I guess as long as I can plainly see it is unregistered, then I can buy any DDR3 1333-1600 1.5V ECC UDIMMs, no matter the board I choose. Any PC3-10600E or PC3-12800E 1.5V.
Thanks!
