Memory Support

The X8DTL-3/-i/-3F/iF supports up to 24 GB Registered ECC DDR3 1333 MHz/1066

MHz/800 MHz in six DIMMs.

Note: Memory Speed support depends on the type(s) of CPU(s) used.

DIMM Module Population Conﬁ guration

For memory to work properly, follow the tables below for memory installation:

Memory Population for Optimal Performance

-For a motherboard with One CPU (CPU1) installed

(To Populate P1-DIMM slots)

Branch 0 Branch 1 Branch 2

3 DIMMs P1-1A P1-2A P1-3A

Memory Population for Optimal Performance

-For a motherboard with One CPU (CPU2) installed

(To Populate P2-DIMM slots)

Branch 0 Branch 1 Branch 2

3 DIMMs P2-1A P2-2A P2-3A

Memory Population for Optimal Performance

-For a motherboard with Two CPUs installed

Note 1: Due to OS limitations, some operating systems may not show

more than 4 GB of memory.

Note 2: Due to memory allocation to system devices, the amount of

memory that remains available for operational use will be reduced when

4 GB of RAM is used. The reduction in memory availability is dispropor-

tional. (See the following Table.)
