Memory Support

The X8DTN+ Motherboard supports up to 192 GB Registered ECC or up to 48GB
Unbuffered ECC/Non-ECC DDR3 1333 MHz/1066 MHz/800 MHz in 18 DIMMs.
Note: This is current memory support based on the memory modules
available on the market at this time. Memory Speed support depends on
the type(s) of CPU(s) used.
