One quick question, someone who knows about RAM.

[Taybox]

This is the memory i have in my current computer. I dont know much about it. If i take it out completely, can i replace it with the link below.

Memory ( 2048MB [1024MB X2] DDR2-800 PC6400 Memory Module Corsair-Value or Major Brand )


My old memory sayd PC6400, the new one says PC2 6400. I dont know what that means or if it matters?

CORSAIR 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory -
http://www.newegg.com/Product/Produc...82E16820145184 (replacing the old RAM) will it fit the slots?

[Taybox]

also im not sure bc im not at home

how many slots are usually available for RAM additions in a desktop?

[Taybox]

bc if it has an EXTRA 2 slots, i could just add this 4 gig to my already 2 gig, which would be awesome!

the 240 pin will tell you if it will fit or not, the one you are buying has 240 pin but i dunno about your desktop, when you get home pull a stick out and look at the sticker on it, if it's 240 you are good to go, if not go with whatever size you have.

PC6400

PC6400 and PC26400 are just the model numbers and that's it. Theres no difference its just different ways of saying the same thing.

Do you have vista 64?

im not up to date on the PC6400 and PC2 6400. let me read up on that.


edit: after reading some sites, there's no difference. its basically a labeling thing. if you have DDR2 ram, its PC or PC2. just make sure the numbers at the end match and you should be alright.

edit2: im slow today. =/

I assume you would be looking to have a total of 6GBs of ram for your system?

keep in mind Windows has limits on how much memory it recognizes and therefor uses. Here's a quickbreakdown:

32-bit versions of Windows XP: 3.2GB

32-bit versions of Windows Vista Home Basic, Home Premium, Business, Enterprise, and Ultimate: 4GB
32-bit Windows Vista Starter: 1GB
64-bit versions of Windows Vista Home Basic: 8GB
64-bit versions of Windows Vista Home Premium: 16GB
64-bit versions of Windows Vista Business, Enterprise, and Ultimate: 128GB

my question on RAM:

Is it possible to mix RAM modules that have different timing?
For example, i currently have these: http://www.newegg.com/Product/Produc...82E16820211066
but i also want to get these (rebate *drools*): http://www.newegg.com/Product/Produc...82E16820227198

existing modules: timing is 5-5-5-18, 1.8volts, CAS latency is 5.
new modules: timing is 4-4-4-15. 2.1volts, CAS latency is 4.

will having 4 gigs total, two of the old and two of the new, cause any conflicts or instabilities? they're both 800MHz DDR2s.
