Neoseeker has published a review of Asus' P5B-E.

]quote]The last motherboard I reviewed, the Gigabyte GA-965P-DS3, reached a record stable 3.64GHz (455x8) overclock for us with our Conroe E6400 - however the Asus P5B-E just blew past it, setting a whole new stable FSB record - 480MHz with a 7x processor multiplier - heck, it ran at 505MHz FSB with a 6x processor multiplier.
