ChipsetThe Intel X38 and X48 derivative did not bring what people expected, it was tuned for high-end quad core overclocking and not for Wolfdale; therefore the outcome can be predicted quite easily: stay clear if you want high FSB.
Now, we may exaggerate a little bit. The Quantum Force team of Foxconn worked really hard to produce a high-end X48 motherboard that could deliver high FSB speeds. At first, I was a little bit skeptical, because no one could even hit anywhere close to 570MHz rock stable, however, recently they have released a new bios which seemed to have solved a lot of problems.

these voltage guidelines at XS, a group of Italian overclockers managed to hit very high speeds.

If we're able to get a board on our testbench, we'll be more than happy to give you our opinion and let you know whether it is a must-have or not.
