Not really . Didn't notice it till it hit 5ghz on stock volts, that cpuz is not reporting fsb correctly. 266 in BIOS iirc. 1.61.3 seems to work fine though.
It's a team comp, so you have to be the best in your team (overclock.net) for your score to show. FTW is beating you with 10k points, so you have to beat him for your score to be shown.

I think the difference is whether it is part of the chipset (integrated) or built onto the board as a separate chip or add in card (mobile). The GMA is part of the chipset, and the GT540M is a separate chip.
