View Full Version : RAM question - what to buy?
09-20-2011, 09:11 AM
I'm looking to upgrade my mother-in-law's RAM on her Windows Vista 32-bit computer.
I ran CPU-Z on her machine and she has 1GB of DDR2 PC2-6400 (400Mhz).
Here's the problem though:
I want to buy 2GB of RAM to add to the 1GB she already has (so 3GB total).
I did some quick research online and couldn't find this exact memory module. The closest one is PC2-6400 (800Mhz). Is this compatible? or should I be looking at matching the 400Mhz?

PC2-6400 is what you're looking for. The 400MHz versus 800MHz is probably the difference between showing the single data rate versus the double data rate. Post the make and model of the motherboard and what CPU she has.

Post the make and model of the motherboard and what CPU she has.Here you go:
Acer Aspire M1200
AMD Athlon 64 LE-1640 2.70Ghz

Yeah, PC2-6400 is what will work.
Just keep in mind that this will no longer be running in dual channel. It won't make any difference to her. Also, please read the manual for the motherboard to see about the slot configurations.

You need to check the memory timings and voltage as you will need to match the exact settings as your current memory. You should probably purchase the same brand too. You don't specify if you have one or two memory modules. If you have two, you will need two 1GB sticks to use dual channel mode.

She currently just has one memory module and 4 slots on her motherboard.
