Expansion Slots
Including six 32-bit/33MHz PCI, one CNR and one AGP 8X slots. The
PCI
local bus throughput can be up to 132MB/s. The
Communication & Nectworking Riser (CNR)
slot provided from AK77-8X / AK77-8XN can support CNR interface for a
Modem/Audio card. The
Accelerated Graphics Port (AGP)
specification provides a new level of video display sophistication and
speed. The AGP video cards support data transfer rate up to 2.1GB/s. As AK77-8X / AK77-8XN includes one AGP expansion
slot for a bus mastering AGP graphic card, For AD and SBA signaling, AK77-8X / AK77-8XN can support 133MHz 2X/4X/8X
mode. Of six PCI slots provided, all of them support master PCI slots for arbitration and decoding functions.
Memory
With VIA Apollo KT400 chipset, the AK77-8X / AK77-8XN can support
Double-Data-Rate (DDR)
RAM. The DDR RAM interface
allows zero wait state bursting between the RAM and the data buffers at 333/266/200 MHz. The six banks of DDR RAM can be
composed of an arbitrary mixture of 64, 128, 256, 512MB x N DDR RAM and maximum up to 3GB. The AK77-8X / AK77-8XN
allows DDR RAM to run at either synchronous or pseudo-synchronous mode with the host CPU bus frequency
(333/266/200MHz).
LAN Port (AK77-8XN only)
On the strength of RealTek RTL8100BL controller on board, which is an highly-integrated Platform LAN Connect device, it
provides 10/100 Mbps Ethernet for office and home use.
On-board AC97 Sound
AK77-8X / AK77-8XN uses the
AC97
CODEC RealTek ALC650 chip, which supports high quality of 5.1 Channel audio effects.
This on-board audio includes a complete audio recording and playback system.
