Default Need Help Replacing Memory in Laptop

I'm on the road to a memory upgrade. Looking for the fastest DDR2 SODIMM 200pin laptop memory to match my processor. Here's my processor specs:

From CPU-Z

Intel Mobile Core 2 Duo T5550 @ 1.83GHZ
Socket P (478)
Core Speed 997.5mhz
Multiplier X6
Bus Speed 166.3mhz
Rated FSB 665.0mhz

I have 2 slots that I want to replace and the maximum memory my computer can handle is 4GB. Any recommendations?

I need the model number of your laptop to see what RAM speeds it supports. You don't want to buy the fastest ones possible, just to find out it downclocked them.

I'd highly recommend going to http://www.crucial.com/
You can run a Hardware Scan and it can make exact recommendations for you. Very accurate and very easy. Goodluck!

I have the HP Pavilion DV2915NR Laptop. I've been to crucial and ran their memory tool, basically I'm looking at PC25300 or PC26400 DDR2 SODIMM 200pin memory. What's in my laptop now is (2GB + 1GB) PC25300 (333mhz) memory cards. Running Windows 7 Home. My computer supports dual channel memory, so I want to get two of the fastest cards that my computer can handle. What do you guys think about these two?

Kingston HyperX 4GB (2 x 2GB) 200-Pin DDR2 SO-DIMM DDR2 667 (PC2 5300) Dual Channel Kit Laptop Memory Model KHX5300S2LLK2/4G

or

G.SKILL 4GB (2 x 2GB) 200-Pin DDR2 SO-DIMM DDR2 667 (PC2 5300) Dual Channel Kit Laptop Memory Model F2-5300CL4D-4GBSQ

why not the DDR2 800?

I personally would go with Kingston. Better timings

Do you have Windows 7 32 bit or 64 bit? If it's 32, you can't use much more than 3GB...it's like 3.15GB or something.

It depends on your set up.


32 bit can allocate 4gb of ram, but that number includes ALL ram, including dedicated video ram, and other things. So if you don't have a video card with a lot of vram you should get most of it.

I have windows 7 64bit. I would like to jump up to DDR2 800, but I heard somewhere that you should match your processor's FSB to the memory. Is that true?

Well if you get memory that's faster, it can be bottlenecked. But it doesn't matter pricewise. I think it's like 2 dollars more from 667 to 800. It can't hurt, especially if you plan on keeping the memory and possibly upgrading the cpu later.
