"The ECS NF650iSLIT-A motherboard supports every Socket 775 processor on a 533/800/1066 MHZ FSB, from the Celeron D to the Pentium 4/D/XE series, and of course the Core 2 Duo/Quad processors. It will also do 133MHz FSB through overclocking, so that potentially brings the Intel Penryn core into the fold as well. Onboard goodies include dual PCI Express slots for SLI, a Gigabit network connection, 7.1 channel High Definition audio, four Serial ATA II ports, two IDE channels and the usual collection of USB jacks. The ECS NF650iSLIT-A is built with the nVidia nForce 650i Northbridge (C55) and nForce 430 (MCP51) Southbridge."
