Hey tks for your quick reply. I actually have the 1.0 bios and just sees that a 1.A0 is available (update cpu module; update marvell lan rom version).
I will update.
You said that the ddr2-1066 is supported. Must I install DDR2-1066 just because it's better performance than my DDR2-800 or simply because the DDR2-800 doesn't work with the Q9550 ?
And last newb question : Is Yorkfield is the same thing as Penryn ? Because on the msi website it said the p35 express is compatible with the Q9550 Yorfield, and when I'm going online to buy one it's said : Q9550 Penryn.
Tks again !
