Q6600 Kentsfield + Asus 680i Striker Extreme

[eva2000]

Continuation from E6600 adventures at http://www.xtremesystems.org/forums/...d.php?t=127331

Seems Asus 680i Striker Extreme still has an FSB limit like all 680i boards when it comes to Kentsfield. Although it seems Asus 680i Striker Extreme does a bit better on FSB front than other 680i boards.
