2gb ddr2 vs 3gb ddr2 (both 667mhz)

[corujo712]

Is there much performance difference between the two when running vista premium 32bit?
Its for a dell XPS m1530

3GB RAM has slightly lower memory bandwidth, as discussed in the dual channel RAM guide, but overall Vista will feel faster with 3GB since it will use any spare RAM to cache files which it thinks you will be wanting to use.

The 3gb will be better and make for smoother computing even tho it loses the full dual channel.

Don't upgrade through DeLL too expensive. So get 2GB and see what you think.

[ViciousXUSMC]

everyday performance will be almost the same, you probably wont even notice. You really have to try to peg the system with alot of memory usage or play certain types of games to use 3gb.

Just curious, how are you going to get the 3gb?

Well if my 1st grade math serves me well, it's going to be something like this:

1 + 2 = 3

haha, classic! Simple math, but that's exactly it.

You did well, you get a gold star but remember to raise your hand before answering. The question was for the OP :-)

The reason I ask is, do any of know for sure if that MOBO will run assymetrical dual channel with 2 unmatched modules or, will it revert to single channel? Or, will it run it 1gb + 1gb dual channel and drop 1gb due to the unmatched modules?

1 + 2 = 3

So does 2+1=3 or 4-1=3. You know what he was thinking! So to answer the next question, No they don't have to match.
