533/667MHz compatibility general question

My laptop uses 2x 512MB DDR II - 533. Is it a safe assumption that it can use DDR II - 667?

If anyone can find out information on memory for the Packard Bell MV46-008 (or MV45-008) as the shop seemed to be confused with what type mine is, naming it an MV46-008, but lacking the ATI graphics like the 46 should have.

I'm assuming it can take 2GB RAM since it's already got 1GB RAM, plus its a Media Center laptop which is 'Vista Cabable' according to the lil sticker.

Intel Core 2 Duo Centrino T5200 @ 1.60GHz
1024MB DDRII-533 RAM
128MB Intel GMA 950/945GM
Windows Media Center SP2
£389 (was it a good purchase???)

Yes, the DDR2-667 will just be run at DDR2-533 speed, as all the RAM in the system needs to be run at the same speed.

no no, i'd take all 533's out (2x512) and replace with 667s (2x1024) I wouldnt mix 533s with 667s. I'm just wondering if a laptop that came with 533s would run 667s.

Certainly it should run them; what speed they are run at depends on the laptop. However, there can also be incompatibilities, so it's best to buy RAM from a vendor that guarantees they will work in your laptop or your money back.
