7. Support USB2.0 Connector
6. Memory & AGP Voltage Adjustment
With our considerate design, you can adjust memory and AGP voltage in BIOS. The
memory voltage range is from 2.5V to 2.65V and the AGP voltage is from 1.5V to 1.6V.
This motherboard provides six
USB
connectors to connect USB devices, such as mouse,
keyboard, modem, printer, etc. There are four connectors on the back panel. You can use
proper cables to connect the Front USB connector to USB modules or front panel of
chassis.
9. IEEE 1394 Connectors (for AK79D-400 1394)
With IEEE1394 MAC Embedded in nForce2 Ultra 400 (with AGERE FW802), the IEEE 1394
provides data transfer rate up to 400Mb/s, and USB1.0/1.1 just has 12Mbps. Hence, the IEEE
1394 interface can connect with the devices that need high data transferring performance,
such as digital camera, scanner or others IEEE 1394 devices. Please use the proper cable to
connect with devices.

8. Memory Module (128-Bit DDR Dual Channel)
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 5.4GB in advanced 128-bit mode. This motherboard supports DDR400/333/266 with
Maximum capacity up to 3GB.

Warning:
nForce2 Ultra 400
chipsets do not support earlier CPU
and Memory that runs at FSB200
(100MHz x 2) and DDR200,
therefore please DO NOT use
FSB200 CPU and DDR200 RAM on
this motherboard.
