2GB ram lat. question.

I have the msi neo2 and I am in need of being able to run 2 GB of ram. I am looking for the lowest timings on 1GB sticks I can find so I can still run dual channel. I have 4 512 now but it is not stable unless I drop back to 333 speed and 2t. Any suggestions?

I'm using 2 / 1gig sticks of Gigaram (get it at newegg). 11.5 x 230 with timings at 2.5-3-3-11. I relly like this brand, you might give it a look.
