Introduction of nForce4 Motherboards 1-1 Motherboard Features The EVGA 133-P4-NF51-XX motherboard is based on the NVIDIA nForce4-SLI SPP (System Platform Processor for Intel Edition) chipset and nForce4-SLI MCP (Media and Communication Processor for Intel Edition) chipset technology, which supports the innovative 90nm Dual-Core Intel® Pentium® D Processor 840, 830, and 820 with Intel® Hyper-Threading Technology. The motherboard delivers leading-edge performance with both reliable multi-tasking from dual core Intel® Pentium® D Processor and the NVIDIA Scalable Link Interface Technology. With the latest SLI ready graphic accelerators from NVIDIA and support for dual channel DDR2 667MHz memory (expandable to 4.0GB DIMM), this motherboard is ready to meet the demanding usage of computing in the future. Also featured on this motherboard is the advanced dual GPU support of the NVIDIA nForce4-SLI SPP (System Platform Processor for Intel Edition), with 1066 MHz Front Side Bus that allows for data transferring with 133MHz / 166MHz / 200 MHz / 266 MHz memory clock frequency for Dual channel DDR2 400/533/667MHz DIMMs. The NVIDIA nForce4-SLI MCP (Media and Communication Processor for Intel Edition) chipset supports ULTRA ATA 133, Serial ATA RAID 0, 1, 0+1, and Serial ATA2 RAID0, 1, 0+1 functions to accelerate hard disk drives and guarantee data security. The motherboard provides Gigabit LAN by using the Marvell Giga-LAN controller which supports 10M/100M/1Gbps data transfer rate and full duplex or half duplex transportation. The embedded 8-channel AC’97 CODEC is fully compatible with Sound Blaster Pro TM standards and offers you home cinema quality and complete software compatibility. Colorful and intuitional placement design of three PCI-Express graphics slots (Two symmetrical PCI-Express x16 [x8 effective speed] graphics slots in yellow deliver up to 2Gbyte/sec data transfer rate at each relative direction which is fully compatible with the latest NVIDIA SLI Technology [this applies to the SLI version of the motherboard only]). One PCI-Express x16 graphics slot offers 4Gbyte/sec data transfer rate at each relative direction which gets 3.5 times more bandwidth than AGP 8X and up to 8Gbyte/sec concurrent bandwidth at full speed to guarantee full operational multi-GPU graphics power and avoid any possible SLI hardware installation error (SLI version only). One PCI-Express x1 I/O slot offers 512Mbyte/sec concurrently, over 3.5 times more bandwidth than PCI at 133Mbyte/sec, tackling the most demanding multimedia tasks.
