2-1. Features of NF7/NF7-M/NF7-S Motherboard
™
™
™
This motherboard is designed for AMD Socket A Athlon
XP, Athlon
and Duron
processors. It
supports the AMD Socket-A structure, with up to3 DIMMs DDR 200/266/333 (Max. 3GB), 2 DIMMs
DDR 400 (Max. 2GB) of memory, super I/O, USB 2.0, IEEE 1394, Serial ATA and Green PC functions.
(For individual NF7 Series specification, please refer to 2-2. Specification.)
The NF7/NF7-M/NF7-S uses the NVIDIA nForce2 SPP/IGP and MCP2-T/ MCP2 chipsets to make the
evolutionary move from PC 100/PC 133 SDRAM to PC 1600/PC 2100/PC 2700/PC 3200 DDR SDRAM,
and increase the speed of the system and memory buses from 100 MHz to 200 MHz. Its 200/266/333MHz
memory interface supports a wide range of PC 1600/PC 2100/PC 2700/PC 3200 DDR SDRAM memory
devices now on the market. DDR SDRAM is the newest memory standard. It provides the maximum
transmission bandwidth and also greatly improves data transmission delays. This feature improves system
performance and speed, especially with multimedia environment applications.
NVIDIA nForce2 SPP/ NVIDIA nForce2 IGP is a system bus, or Northbridge, and provides a high
TM
performance with 128-bit Memory controller and high-speed 800MB/sec HyperTransport
interface to
the MCP-2T/2 (Media & Communication Processor). With NVIDIA's DASP (Dynamic Adaptive
Speculative Pre-Processor) technology that can intelligently predict and prefetch requests from AMD
Athlon XP Processor, NVIDIA nForce2 SPP/NVIDIA nForce2 IGP can boost your system. The 128-bit
memory controller integrated with the GPU on chip provides up to 6.4 GB/sec bandwidth for system
memory, and gives you highest performance and cost-effective platform. The NVIDIA nForce2 also
consists the 333 MHz Athlon System Bus, the 400 MHz DDR Memory Subsystem, the AGP 8X (0.8V) /
4X (1.5V) modes Graphics Interface (AGP 3.0 Compliant) and the 33 MHz/32-bit PCI Bus Interface (PCI
2.2 Compliant), including arbiter.
NVIDIA MCP2-T/ NVIDIA MCP2 is call "south bridge" and supports Ultra DMA 133 function. This
means that it provides speedier HDD throughput boosting overall system performance. Ultra DMA 133 is
the newest standard for IDE devices. It enhances existing Ultra DMA 33 technology by increasing both
performance and data integrity. This new high-speed interface almost doubles the Ultra DMA 66 burst
data transfer rate to 133 Mbytes/sec. The result is maximum disc performance using the current PCI local
bus environment. Another benefit is the ability to connect four IDE devices to your system, either through
Ultra DMA 66, Ultra DMA 100 or Ultra DMA 133. With this, you will have more flexibility to expand
your computer system. Moreover, expanded connectivity via USB ports gives users an easy way to
connect to today's hottest audio and video peripherals. On-board 10/100 LAN provides high-speed
networking capabilities, and built in AC/MC'97 6-channel audio delivers a rich multimedia experience.
NF7-S's built-in one Silicon Image SIL3112A Controller provides two Serial ATA connectors onboard;
you can connect one Serial ATA device to each of them, since Serial ATA will be a point-to-point
protocol. What is Serial ATA? Serial ATA is an evolutionary replacement for the Parallel ATA physical
storage interface. Serial ATA is scalable and will allow future enhancements to the computing platform.
This new high-speed interface expands data transfer rate to 150 MB/sec (1.5 gigabits/sec). The result is
maximum disc performance using the current PCI local bus environment. Other benefits are: more
flexible power tolerances, cables can be smaller and more efficient (this can improve the airflow and heat
inside the chassis), easy to configure devices, etc. This interface is designed to connect PC internal
devices. If you want to connect outside peripherals, IEEE 1394 and USB 2.0 interfaces will be the
solution. (For NF7-S only)

NF7/NF7-M/NF7-S provides high flexibility to users building AMD Socket A Athlon
XP, Athlon
and
™
Duron
systems. It provides the option of 200/266/333 MHz CPU and memory bus combinations.
