Introduction of 939GT4 Motherboard Series
1-1 Features of motherboard
The 939GT4-SLI-D / 939GT4-SLI-G / 939GT4-SLI-P / 939GT4-Ultra-G / 939GT4-STD-G
motherboard is based on NVIDIA nForce4-SLI, nForce4-Ultra, and nForce4 single chip
technology which supports the innovative 64-bit AMD Athlon64 FX and dual core multi-
tasking Athlon64 X2 processors with HyperTransport Technology. The 939GT4 SLI
motherboard series deliver the leading-edge performance with both of the benefits from 64-bit
multi-tasking dual core AMD processors and NVIDIA Scalable Link Interface Technology
with the latest Dual PCI Express for NVIDIA Dual Graphic Processing Unit ready platform.
Utilize the 64-bit multi-tasking socket 939 solution and the dual channel PC3200 DDR
memory size expandable to 4.0GB, the 939 GT4 SLI motherboard series meet the demanding
usage of computing in the future.
The motherboards carry the advanced dual GPU supported NVIDIA nForce4, nForce4-SLI,
and nForce4-Ultra single chip with 1000 MHz HyperTransport system bus of data
transferring and provided with 133MHz / 166MHz / 200MHz memory clock frequency for
DDR266/DDR333/DDR400 DDR Module and Dual channel function. NVIDIA nForce4
single chipset offers ULTRA ATA 133, Serial ATA RAID 0, 1, 0+1, and Serial ATA2
RAID0, 1, 0+1(Only for 939GT4-SLI and 939GT4-Ultra motherboard series) functions
to accelerate hard disk drives and guarantee the data security without failed in advanced
computing performance.
The 939GT4 motherboard provides optional 10 / 100 LAN function with Realtek 8201CL
LAN PHY or dual Gigabit LAN function by
using the Marvell 88E8053 Giga-LAN
controller or Marvell 88E1111 10 /100/1000 LAN PHY which supports 10M / 100Mbps or
10M / 100M / 1Gbps data transfer rate. Embedded 8-channel AC'97 CODEC is fully
compatible with Sound Blaster Pro standards that offers you with the home cinema quality
and absolutely software compatibility.
Colorful and Intuitional SLI placement design offers three PCI-Express x16 graphics slots (Two
symmetrical PCI-Express x16 graphics slots in light green deliver up to 2Gbyte/sec data
transfer rate at each relative direction which is fully compatible with the latest NVIDIA SLI
Technology. One PCI-Express x16 graphics slot offers 4Gbyte/sec data transfer rate at each
relative direction which get 3.5 times of bandwidth more than AGP8X and up to 8Gbyte/sec
concurrent bandwidth at full speed.) to guarantee the fully operational multi-GPUs graphics
power and avoid the possible SLI hardware installation error. One PCI Express x1 I/O slot
offers 512Mbyte/sec concurrently, over 3.5 times more bandwidth than PCI at 133Mbye/sec,
tackling the most demanding multimedia tasks nowadays.
Embedded USB controller as well as capability of expanding to 10 of USB2.0 functional
ports delivering 480Mb/s bandwidth and rich connectivity, these motherboards meet the
