Congratulations on purchasing the L4S5MG/GL mainboard. The L4S5MG/GL
mainboard is a Micro ATX mainboard that uses a 4-layer printed circuit board
and measures 244 mm x 220 mm. The mainboard features a mPGA Socket
478 that accommodates Pentium 4 processors supporting data transfers up to
400 MHz.
The L4S5MG/GL incorporates the XP4GL chipset which combines support for
the new high-bandwidth Double Data Rate (DDR) 266/333 SDRAM, Inte-
grated VGA and the AC 97 audio codec.
Note:
SDRAM provides 800 MBps or 1 GBps data transfer depending on whether
the bus is 100 MHz or 133 MHz. Double Data Rate SDRAM (DDR SDRAM)
doubles the rate to 1.6 GBps or 2.7 GBps by transferring data on both the ris-
ing 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.
