F2-6400PHU2-2GBZX - Capable of 450MHz at 5-5-5?

Trying to put together a budget E6600 Conroe rig and the GBZX sticks have a great price point ($190 per 2GB), but I'm wondering if it's realistic to assume they can run 450MHz with loosened timings.

Anyone have any experience with the ZX? G.S. Tech, have you ever tested them?

Thanks in advance :)

G.S. Tech, you there?

Anyone?

no, DDR2 800 2gbhz is about 400~420 CL4, CL5 will not help

Thanks for the help, HZ it is then. ;)
