Geil Ultra ram decent for the price?

Was thinking to get a set of these

under $50 shipped for a 512mb (2x256MB) wondering if anyone has had oc experience with these. Reading NewEgg reviews, it goes both ways..some have had oc'd with success, others can't get past 203Mhz fsb...

Running 2500+ mobile on an NF7S-2 - any help would be greatly appreciated thank you!!!

I think a better investment would be a single stick of 512. You don't gain that much with dual channel with an nf2 and down the road you will probably want to upgrade to 1 gig or even an A64 system. IMO the 2x512 configuration would more versatile in the long run.
This single stick is a tick faster and cheaper than the dual you have listed.

There are many others to choose from in the price range. Good luck.
