Memory types

The motherboard comes with Double Data Rate 3 (DDR3) Dual Inline Memory
Modules (DIMM) sockets.
WARNING: Only DDR3 RAM modules can be used on this motherboard.
The figure illustrates the location of the DDR3 DIMM sockets:
IMPORTANT: Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules from the
same vendor.

Memory module rules and configurations

DIMM Socket Labeling
DIMM2
Black
(Channel A)
Note: DIMM2 is the socket closest to the CPU and DIMM5 is the socket farthest
from the CPU.
Memory Module Insertion Rule
1. Insert modules starting from the DIMM closest to the CPU.
2. Insert 2GB modules first, then 1GB modules if both are used.
3. Fill each channel (two sockets) with modules to fully utilize triple channel
performance.
IMPORTANT: One of the blue sockets (DIMM1/3/5) must be populated.
