What ddr for Celeron D 320 (2.4 GHz) ?

Hi,

I recently purchased a second hand Celeron D 320 as I have an Asus P4P800 Deluxe. I used to pair a P4C 2.4 GHz with 2 modules of ddr 400 in dual channel. It ran well overclocked to 3.1 GHz with the Ram ratio reduced to 333. I know that the i865 chipset handles well a different ratio for Ram and FSB but I wonder what would be the impact on the Celeron. I do not intend to overclock and I have a module of ddr 266. Should I make it run in dual channel or upgrade to a faster memory? I try to use what I have but I don't want to spend much. I couldn't find much info about the impact of ddr frenquency and single/dual channel mode for that processor. By the way, it will be only for internet browsing, music, movies and Dvd burning. Any help would be much appreciated.

Well no one seems interested into a crappy Celeron around here !
If you just know an article speaking about the ram impact on it, would be cool as I didn't find any.
Come on people! Help needed here!
