ASUS P4G800-V motherboard user guide
1-13
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)
