6. Memory Module
9. Support LAN onboard
In the past, we used to have 64-bit memory bandwidth for memory access. No matter how
many memory modules have been installed, though capacity added, the speed of access
remains the same. With 128-bit dual channel introduced, it doubles the memory
bandwidth up to 6.4GB in advanced 128-bit mode. MX4SG-4DL and MX4SG-4DN
support this dual channel mode. MX4SG-4DL and MX4SG-4DN support DDR
400/333/266 with maximum capacity up to 4GB. MX4SPB-N supports DDR 400/333/266
with maximum capacity up to 2GB.
This motherboard provides eight USB 2.0 ports to connect USB devices, such as
mouse, keyboard, modem, printer, etc. There are four ports on the back panel. You can
use proper cables to connect the Front USB connector to USB modules or front panel of
chassis.
8. AGP 8X Expansion Slot
This model provides an AGP 8X slot that is the latest AGP specification. The AGP 8X calls
for the bus to operate at the basic AGP 66-MHz clock frequency and the bandwidth are
2.1Gbytes/s. It is a great improvement on the performance of 3D graphic. AGP supports
only memory read/write operation and single-master single-slave one-to-one only. AGP
uses both rising and falling edge of the 66MHz clock, for 4X AGP, the data transfer rate is
66MHz x 4bytes x 4 = 1056MB/s. Now the transfer rate is 66MHz x 4bytes x 8 = 2112MB/s.

On the strength of Broadcom Gigabit LAN controller (MX4SG-4DL) or Broadcom BCM4401
LAN controller (MX4SG-4DN and MX4SPB-N) on board, this motherboard provides 10/100
Mbps (for MX4SG-4DL, it is 10/100/1000 Mbps) Ethernet for office and home use. The
Ethernet RJ45 connector is located on top of USB connectors. The right hand side LED
indicates link mode, it lights in orange whenever linking to network. The left hand side LED
indicates the transfer mode and it lights in green when data is transferring in 100Mbps
(never lights while in 10Mbps), but lights in orange when transferring in Gigabit’s mode
(MX4SG-4DL). To enable or disable this function, you may simply adjust it through BIOS.
