Ramm Question

Alright...I was just wondering something...currently in a vista machine im building up I have 2x512 mb DDR 667. I have two open slots, and from what I read about my mobo I must install new ramm in pairs. Which I already knew, but when I upgraded my XP machine I ended up with 4 sticks of 512.

My question....can I add two 1 gig sticks

these

with my current 2X512mb to get 3 gigs? Or do I have to buy 2 more 512's..just to equal 2 gigs...if thats the case, im just going to buy the two 1 gig sticks and take the 512's out completely. But I was just curious if I could get away with 3 gigs...Thanks. I know its late, but I would really like some help. Thanks!

JUST look at how cheap that memory is...

for people interested

XP machine

P4 2.6

9800 PRO AIW

1 GIG

VISTA CURRENT

AMD X2 4000+

1 gig

Crappy X1200 onboard GPU

UPGRADE

XFX 8600 GT

along with the mentioned memory upgrade....CPU isn't the best, but it'll do.

Thanks again.

Yeah I plan on upgrading to the

XFX 8600 GT its currently $139.99 at newegg, and it can play UE3 games @ high medium/low high settings...if you know what i mean...

I don't want to max out everything...an 8800 is to much money....

my plan is in a couple of years to upgrade to SLI with the 8600. with a new cpu and a new case and mobo etc.
