P4VMM mainboard is a Micro-ATX mainboard that uses a 4-layer printed
circuit board and measures 240 mm x 244 mm. The mainboard features a c
that accommo-dates Pentium® 4 processors supporting frontside bus (FSB)
speeds up to 400 MHz. The P4VMM incorporates the VIA® P4M266 chipset which
combines support for the new high-bandwidth Double Data Rate (DDR) SDRAM,
and the AC 97 audio codec.
Note: SDRAM provides 800Mbps or 1Gbps data transfer depending on
whether the bus is 100MHz or 133MHz. Double Data Rate SDRAM (DDR SDRAM)
doubles the rate to 1.6Gbps or 2.1Gbps by transferring data on both the
rising and falling edges of the clock. DDR SDRAM uses additional power and
ground lines and requires 184-pin DIMM modules rather than the 168-pin
DIMMs used by SDRAM.
