Hello all... Right now I have 2 x 1GB dimms running in dual channel mode. When I eventually upgrade to Windows 7, I'd like to get the 64-bit version and upgrade to about 4GB. Would it be better to use 2 x 2GB in dual channel or just add two dimms to make 4 x 1GB? Would there be a large performance hit by not running in dual channel mode? Thanks for the help in advance!

4x1 would be dual-channel.

Is that true? I was under the impression that once you added more than 2 dimms it would not be dual channel anymore because you would have more than 2 (dual) sticks. I guess I misunderstood the concept of dual channeling. So just to clarify, I can fill up all the memory slots on my motherboard and it would still be dual-channel?

You can have more than 1 DIMM per channel. So as long as you get another 2 DIMMS (for the total of four) you should be okay.

For best results, make sure they're all the same capacity and speed, i.e. don't mix 1GB sticks with 2GB sticks, and don't mix PC5300 with 4400 or whatever. Just get 4 of the exact same stick and you're good to go.

Great! For some reason I thought it was limited to two sticks. Thank you for your help everyone.

You only need replication across a single channel. There is no performance hit (with respect to dual versus single channel) in running 1x1 and 2x2. Each channel is independent of the other in terms of interleaving, and they will never share data directly.

This machine is, at the moment, running a pair of 2GB sticks in channel 1 and a pair of 1GB sticks in channel 2. Both channels are interleaved.

It is advisable, but not necessary, to match rated speed and timings within a channel.

Ah, didn't know that. Joke's on me, I suppose. =p

I knew there was a reason people don't trust me to help put their computers together.

Advisable being the key word. I suppose it depends upon the quality of your motherboard and BIOS, but I have seen instances where a mismatched CAS latency across a single channel has caused issues (BSOD). But of course I have only seen this problem with "upgraded" pre-builts.
