The Inquirer reports NVIDIA's nForce 4 SLI Intel Edition isn't entirely compatible with the dual-core Pentium 4 processors.
We contacted Nvidia about this, and its Euro spinner came back with the answer that Nforce4-SLI Intel Edition supports Dual-Core Pentium CPU's only if they come from the Extreme Edition family, like the XE 840. Plain vanilla Pentium D support is in the same place as ATI chipset USB 2.0 speed.
