newegg takes forever to load for me when i try direct links like that. but im just going to guess that yes, it will be just fine.
Pretty much anything DDR2 works. I've heard of partial compatability issues with Corsairs DDR1 on DFI Ultra-Ds(didn't run well but still bootable), but that's the only case I've heard of incompatability. For the most part, all ram is made in the same manner, specced the same etc. A lot of ram comes from the same Malasian plant and is then rebranded.
