Good memory for A8V

Hi,

Can anyone tell me some good memory to go in the Asus A8V Deluxe MB?

This is what it has as the req spec but I am unsure of brand (and what all the other numbers mean).... sorry its basic...

I want 1GB (2 x 512) sticks.

- 4 x 184-pin DIMM Sockets support max. 4GB DDR400/DDR333/DDR266 non-ECC un-buffered DDR SDRAM memory
- Dual Channel Memory Architecture
