2.5 - Installing the Memory
Before installing memory, ensure that the memory you have is
compatible with the motherboard and processor. Only DDR2-400
DIMM modules are required. Check the TYAN Web site at:
www.tyan.com for details of the type of memory recommended for
your motherboard.
The following diagram shows common types of DDR2 memory modules.
Key points to note before installing memory:
•
Only DDR2 400 Registered ECC memory modules are
supported.
•
All installed memory will automatically be detected and no
jumpers or settings need changing.
For optimal dual-channel DDR2 operation, always install memory in pairs
beginning with DIMM1 and DIMM3. Memory modules of the same type and
density are required for dual-channel DDR2 Operation. Mismatched memory
may cause system instability.
