The only difference is, you only use 1 slot for a 512 stick, and you use 2 for 2 256's! So keeping possible upgrades in mind, go with 1 512 stick. It's generally slightly more cost effective as well. Performance-wise, I am not aware of any difference whatsoever.

DDR does not HAVE to be installed in pairs, but its performance is better when it is (in pairs).

DDR does not need to be installed in pairs, I have 3 stick of 512mb PC2100 DDR, the only time you would want to have 2 stick of DDR is if you use a DAUL DDR motherboard, in this case as long as you 2 stick the same in a DAUL DDR motherboard then you can have double the performance

In a non daul DDR motherboard it does not make a difference

But yes 512mb stick is much better than 2x 256 as you would have more space for upgrading your RAM

Its not better for troubleshooting. If you have one stick and it fails you are SOL.
If you have two you can try both AND keep the computer running while you get a replacement.

This imo is the best counsel of the lot. When in your house is only one vid card, one psu, one memory stick, whatever, troubleshooting hw is near impossible

Personal opinions....

Performance: there is a slight performance gain in using 2 x 256MB sticks (if they're well matched) over a single 512MB stick. If you compulsively run memory benchmarks, you might even notice it.

Upgrade issues: if you use smaller memory sticks, you run out of available memory slots more quickly.

Redundancy: if a memory stick goes bad, it sucks if it's the only one on your mainboard. With two sticks, you have a backup.

Failure probabilities (2 sticks Vs. 1): with two sticks of memory, you have twice the chance of having a bad stick, but only one-half the chance of not having at least one working stick to run your computer.
