Memory

The mainboard contains four 184-pin DIMM sockets and provides support for up to 8 GB of memory
when four 2 GB DIMMs are installed. Memory is partitioned as two banks of DDR DIMMs. DIMM
1A and 1B make up Bank 1; DIMM 2A and 2B make up Bank 2. Each bank provides 144 bits of two-
way interleaved memory.
The mainboard supports up to four registered, ECC, DDR DIMMs that are compliant with the JEDEC
DDR 266 specification. A wide range of DIMM sizes are supported, including the following:
• 128 MB
• 256 MB
• 512 MB
• 1 GB
• 2 GB
 NOTE
If the operating environment for your system exceeds 30 degrees Celsius and you are installing either
stacked 1 GB DIMMs or 2 GB DIMMs, you will need to install a DIMM cooling duct.
