Fear not, this has nothing to do with male Goats.

I currently have 2x256mb ram paired on my mobo with a spare non paired slot next to them... Now... I want to upgrade to 1gb... So I have two choices...

1. Buy a 512 and put in it the computer.
2. By 2x512, throw the 2x256 out and put the 2x512 in the mobo paired.

Now, I know there's a speed advantage of pairing up which is why I got the 2x256 in the first place, but is it worth it for the extra cost?
Am I going to lose speed by putting a single 512 in or will I just not gain speed.
Will the 2x256 run at one speed and the 512 on it's own run at another... etc etc
You get the general gist of my worry / question I'm sure.
