Has anyone tested the Blades in adjoining DIMM slots?

I really want to know, as i'd be getting 8 GB if i can ever actually buy these in Canada.

I'd prefer to get the better-cooled Blades, but if there will be issues with 4 DIMMs fitting, i'm fine with getting the Platinums.

Anyone?

I'm not asking to test 8 GB...just wondering if you can physically fit them side by side & in what mobo...
