Specs: Windows XP
I have Sony Vaio VGN FS-415B laptop. The Processor is Intel Pentium M 1.73 with 915 GM chipset. I need to upgrade its RAM. Crucial.com memory finder says use "DDR2 PC2-5300; DDR2-667" RAM but kingston.com memory finder tells me to put in "DDR2-533" module. I am confused if both the models are same. I also wanted to install Windows XP-64 bit but i guess my processor supports only 32 bit XP . So, What can I do if i install 64bit OS(if possible!!) or 32-bit XP?

PC2-5300 = 667MHz effective memory speed
PC2-4200 = 533MHz effective memory speed.

Buy the PC2-5300 memory. Your laptop will automatically clock it down to 533MHz.

Yep, the good old Pentium M is a 32-bit CPU, so you're stuck with the 32-bit versions of XP/Vista.

The HTPC:
Pentium M oc'ed to 2.82GHz, 667FSB, 2MB L2
3GB of DDR-800 @ 667MHz
GeForce 9600GT
Blu-Ray
Vista
Modified PowerMac G4 'Quicksilver' case
HDMI to homebuilt 1080p projector

No that's not what he said, what he said was get the 5300 and the computer will adjust it to the lower speed.

Laptops are sensitive to RAM specs and therefore you can't simply rely on any generic RAM with the correct or similar clock speed to work properly.

That is why manufacturers sell brand specific laptop RAM.

I suggest you go to a vendor that has an online scan, or some other means to determine the EXACT RAM sticks for your laptop.

Crucial.com is one such vendor but not the only one. Crucial guarantees the RAM they recommend will work.
