RAM Upgrade?

[Danger Phoenix]

I currently have a Gigabyte GA-K8NXP-9 motherboard with 2 x 512 MB Geil Golden Dragon PC3200 DDR memory.

This memory is a matched pair and is running in Dual Channel mode...

What is the cheapest and most cost effective method of upgrading this? I assume I can't just stick in another 512 MB module as this would stop the Dual Channel mode... so what can I do?

I take it by upgrading you mean adding more memory, my advice would be to buy a 2gb matched pair set and sell what you currently have on the MM or some other auction site.
