Asus P4P800S SE - Manual (Page 22)

1-12 Chapter 1: Product introduction
1.9 System memory
The motherboard comes with two Double Data Rate (DDR) Dual Inline Memory
Module (DIMM) sockets. These sockets support up to 2GB system memory using
184-pin unbuffered non-ECC PC3200/PC2700/PC2100 DDR DIMMs. The
following figure shows the location of the DDR DIMM sockets.
1.9.1 Memory configurations
You may install 64MB, 128MB, 256MB, 512MB, and 1GB DDR DIMMs into the
DIMM sockets using the memory configurations in this section.
Important notes
1. For optimum compatibility, it is recommended that you obtain memory
modules from the same vendor. See the DDR400 Qualified Vendor List
(QVL) on page 1-13.
2. Make sure that the memory frequency matches the CPU FSB (Front Side
Bus). Refer to Table 1.
3. Always install DIMMs with the same CAS Latency.
4. Double-sided DDR DIMMs with x16 (data bus=16bit) memory chips are not
supported due to chipset limitation.
