NForce4
The nForce4 is a motherboard chipset released by Nvidia in October 2004. The chipset supports AMD 64-bit processors (Socket 939, Socket AM2 and Socket 754) and Intel Pentium 4 LGA 775 processors.
nForce4 is the second evolution of the Media Communications Processor (MCP)[citation needed] and incorporates both Northbridge and Southbridge on a single die (the first was nForce3).
The Socket 754 version of the board has the HyperTransport link clocked to 800 MHz (6.4 GB/s transfer rate). Motherboards based on early revisions are mostly referred to as "nForce4-4x" (relating with their ability to handle HT speeds of 4x).
The Ultra version contains all of the features of the nForce4-4x version with the addition of:
Enthusiasts discovered early after the release of nForce4 Ultra that the chipset was identical to nForce4 SLI other than a single resistor on the chip package itself. By modifying this resistor as the SLI is configured, an Ultra can be turned into an SLI.
The SLI version has all the features of the Ultra version, in addition to SLI (Scalable Link Interface). This interface allows two video cards to be connected to produce a single output. This can theoretically double framerates by splitting work between the two GPUs.
On a standard (non x16) nForce4 SLI motherboard, the system can be configured to provide an x16 slot for one graphics board or twin x8 slots for the SLI configuration. A jumper bank must be altered to set these options.
Unlike its AMD Athlon 64 sibling, the Intel Edition is an older chipset as it has both a northbridge and southbridge. As with the older nForce2 chipsets, Nvidia calls the northbridge the "System Platform Processor" (SPP) and the southbridge the "Media and Communications Processor" (MCP). This change in design was necessitated because, unlike the Athlon 64/Opteron, the Pentium 4 does not have an on-board memory controller thus requiring Nvidia to include one in the chipset like in older nForce2. In addition to supporting Pentium 4 processors (with up to a 1066 MHz FSB) the chipset includes support for DDR2 SDRAM. Also like Nvidia's older chipsets, the MCP and SPP communicate through a Hypertransport link, in this case only at (1.6 GB/s. transfer rate) Apart from these differences, the nForce4 SLI Intel Edition shares the same features as the regular nForce4 SLI.
