AMD Crossfire Xpress 3200 Chipset for Core 2 Rolls, But Doesn't Rock

Overclocking? Check!

The highest reliable base clock speed we could run on the DFI LanParty UT ICFX3200-T2W was 475 MHz, which equals FSB1900 speed! This is almost as much as we were able to hit with a P965 motherboard from Gigabyte, the GA-965P-DQ6. However, we consider products playing in the league of 450+ MHz base speeds (FSB1800+) to be excellent overclockers anyway.

Though there are differences between the various chipsets - the 975X doesn't overclock as well as the other chipsets in the table below - the choice of particular motherboard has become more and more important today. Whether you can reach 450-500 MHz base clock speed is not so much a matter of the chipset used: all three main products (AMD's 580X, the Intel P965 and Nvidia's nForce 680i SLI) are capable of running at these clock speeds.

These are the maximum FSB speeds we were able to reach in our test lab. Note that only enthusiast-class motherboards will hit the highest frequencies; our findings do not necessarily mean that an individual product may perform a bit better than what we found. They merely represent the maximum observed for each chipset.
