The nForce x16 chipset supports all current AMD Socket 939 CPUs. The recent launch of the AM2 platform means there's limited upgradeability for the Socket 939 platform, but there are still a wide variety of powerful CPUs on the market on 939, including the FX-60 and 4800+ X2 CPUs. The switch to DDR2 has not shown a meaningful increase in performance over DDR (less than 1% in most cases).

DIMM slots


DDR memory is slowly fading away much as SDRAM memory was a few years ago. Last month for the first time DDR2 memory sold more units than DDR memory. The EVGA board sports four DIMM (Dual In-line Memory Modules). DDR266/333/400 memory is supported with up to 4GB of unbuffered non-ECC DDR RAM supported by the nForce x16 chipset.

The high-end motherboard market is dominated by multiple-GPU motherboards that are based upon either SLI or Crossfire configurations. The choice between the two competing standards is simply whether you want to use two NVIDIA graphics cards or two ATI cards, as SLI does not work on a Crossfire motherboard and vice versa. I won't go into the politics of which solution is better, as that is beyond the scope of this review.

EVGA's nForce SLI x16 board has 2 PCI Express x16 slots for SLI operation. The first nForce4 SLI motherboards had two X16 slots as well, but were limited to 22 PCI Express lanes. This meant that to operate two cards the maximum that could be split was x10 x10. NVIDIA decided to offer 8 lanes per slot in that configuration. The nForce4 SLI x16 platform offers x16 operation for each of the PCI Express slots with two cards installed. Two PCI Express x1 slots and three PCI slots make up the remainder of the device expansion on the EVGA board.

NVRAID


SATA hard disk drives have taken over from the IDE standard, much as DDR2 memory has taken over from DDR. The EVGA board sports four SATA II ports, the minimum I would expect from a motherboard today. The nForce MCP supports up to four devices natively. Supported are RAID modes 0, 1 , and 0+1. Rounding out the EVGA boards drive expansion are two IDE controllers and a Floppy Disk Controller.

Onboard audio is provided by a REALTEK ALC850 CODEC. With the release of the nForce 5xx series, High Definition Audio (HDA) is present throughout the lineup. The nForce4 SLI x16 chipset supports the AC'97 standard in which the ALC850 is a great example of. 7.1 Surrround Sound, 48KHz digital audio, and supports EAX/Direct Sound 3d, A3D and more.

The rear input/output panel of the EVGA nForce4 SLI x16 board provides everything you would expect from the I/O area of a modern motherboard. Four USB 2.0 ports, 6 audio jacks, S/PDIF In and Out jacks a COM1 port, a Parallel port, two RJ-45 jacks for the LAN and PS/2 Mouse and Keyboard ports make up the I/O.
