Epox 9NPA+ Ultra and 2gig DDR sticks

[Whitebread]

I'm happy with the performance of my hardware, save for the amount of memory I've got. I just upgraded to windows 7 x64 and I'd like to increase my installed memory from 2 gigs to 4 gigs. The heatsink I've got installed is large and would make the installation of 4 sticks difficult. Does anyone know if the Epox 9NPA+ Ultra can handle 2 gig sticks of DDR ram?

Thanks
