Can I use both of these?

[MattRiddle]

I originally bought:

Crucial 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Desktop Memory Model CT2KIT12864AA80E

and I am looking to buy a set of 4GB ram (2 sticks of 2GB). I am looking to buy these:

G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory - Retail

and was wondering if I could use all 4 sticks in the same computer.

I remember reading something a long time back that said something about not combining different kinds of memory sticks.

Could I use both of these at the same time?

Thanks!

Well yes, and a different brand at that. The worst that can happen though is your system won't boot up properly, or there'll be a bottle-neck somewhere because of your dissimilar RAM.

Before we get anywhere however, whats your OS? If you're using a 32-bit OS like the standard Windows XP, Vista, or 7, your max is around 3GB anyway.

Only two uses for more than 4 gig .

1/ virtualisation

2/using a 64 bit OS and a 64 bit application

So far the only 64 bit app I know of is Adobe CS4 , but I guess there will be others

Yes you can combine them. The computer will use the slowest timings.
If you have trouble relax the timings, increase memory voltage to 2.1v and increase Northbridge voltage.

In any case if you combine use the slowest timings and the highest voltage of the two sets.

I am just going to buy another 1GB stick of what I have already.

I looked into DDR3 ram, but I'd have to get a new motherboard with the right slot on it to use it, and most likely a new processor for the new slot on the new motherboard. Maybe next update.

From what I've seen around here, DDR3 isn't worth it. What's your CPU and motherboard? i7?
