Need to get some more ram: Dual-channel or single?

[apsd]

Right now I've got one stick of mushkin 512mb in my MSI K8N Neo2 Platinum (socket 939)...

I'm looking to get 1gb more of ram in addition - should I got with dual-channel (512x2) or a single stick?

Is there any performance loss if I have a dual-channel ram mixed with another single stick?

Dual channel.... It'll theoretically boost your performance one fold.
3 sticks = Single channel generally speaking.

So a setup of dual channel 1gb + single channel 512mb on the same mobo is ok?

If you use 3 sticks, they won't run in Dual Channel. However, I believe some Nforce chipset motherboards allow it, but I'm not sure how and which.

You will be able to run dual-channel in cases like so:
Slot 1/3 = Channel A
Alot 2/4 = Channel B

256MB Slot 1
256MB Slot 3
512MB Slot 2

That you give you 1024MB of memory in dual-channel.
You will be able to run dual channel like so: Capacity of channel A = Capacity of channel B.

Yes you could run three sticks but running two sticks in dual channel would be better performing.

I've decided to simply get another identical 512mb stick to complement I have the one now, and put it into dual channel to have 1gb.

Thanks for all the help guys
