Asus P4P800S-X CPU FSB, 800 MHz, 533 MHz, 400 MHz, 333/266 MHz, 266/200 MHz, DDR DIMM Type, PC2700/PC2100, PC2100/PC1600, Memory Frequency, 400/320*/266 MHz

Table 1 Memory frequency/CPU FSB synchronization

This motherboard supports different memory frequencies depending on the CPU FSB (Front Side Bus) and the type of DDR DIMM.

CPU FSB	DDR DIMM Type	Memory Frequency
800 MHz	PC3200/PC2700/PC2100	400/320*/266 MHz
533 MHz	PC2700/PC2100	333/266 MHz
400 MHz	PC2100/PC1600	266/200 MHz

*When using 800 MHz FSB CPU, PC2700 DDR DIMMs run only at 320MHz (not 333MHz) due to chipset limitation.
