Expansion Slots
Including five 32-bit/33MHz PCI slots, one CNR slot and one AGP 8X slot which supports AGP card. The PCI local bus
throughput can be up to 132MB/s. The
Communication & Networking Riser (CNR)
slot provided supports CNR interface for a
Modem/Audio card. The
Accelerated Graphics Port (AGP)
specification provides a new level of video display sophistication and
speed with data transfer rate up to 2.1GB/s.
Memory
With nVIDIA nForce™2 Ultra 400 chipset, the AK79D-400 Max can support dual channel Double-Data-Rate (DDR) RAM. The
dual channel mode allows chipsets to get data in 128 bit. The DDR RAM interface allows zero wait state bursting between the
SDRAM and the data buffers at 400/333/266/200MHz. The three slots of DDR RAM can be composed of an arbitrary mixture of
64, 128, 256, 512MB or 1GB DDR RAM and maximum up to 3GB. The AK79D-400 Max allows DDR RAM to run at either
synchronous or pseudo-synchronous mode with the host CPU bus frequency (400/333/266MHz).
On-board AC97 Sound
AK79D-400 Max uses the AC97 CODEC RealTek ALC650 chip. This on-board audio includes a complete audio recording and
playback system.
LAN Port
LAN MAC embedded in nForce2 MCP-T chipsets and a Realtek RTL8201BL chip onboard, which support 10/100Mbps Base-T
Fast Ethernet and is IEEE 802.3 compliant.
