Asus P4P800-VM - Manual (Page 24)

1-14 Chapter 1: Product introduction
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 400/333*/266 MHz
533 MHz PC2700/PC2100 333/266 MHz
400 MHz PC2100 266 MHz
*When using 800MHz CPU FSB, PC2700 DDR DIMMs may run only at
320MHz (not 333MHz) due to chipset limitation.
* For dual-channel configuration (3), you may:
• install identical DIMMs in all four sockets, or
• install identical DIMMs in DIMM_A1 and DIMM_B1 (blue sockets)
and identical DIMMs in DIMM_A2 and DIMM_B2 (black sockets)
