Can X48 DDR2 mobos use 4GB DDR2-800 DIMMs?

Just curious. I was pretty certain that 4GB DIMM support only came about for P45 and G41 boards, and that X48 (which was really just a binned X38, with support for 400FSB), was limited to 2GB DIMMs.

But if anyone knows for sure, please let me know. I have some chinese 4GB DDR2 DIMMs, that amazingly, work in my P35 DDR2 board, but only at 2GB capacity. I do have a DDR2 P45 board, that I'm going to eventually try them in, but I was wondering about my spare X48 board as well.

I have a Q35 board with 4 x 2 gig DDR2 800 , will only see 2 x 2 gigs DDR2 1066
P35, I don't know.

VirtualLarry, you sure do have a lot of old hardware.

My P45 motherboard only supported up to 2GB DIMMs, although it worked with DDR3, not DDR2.

At that, it was picky as hell about package density.
