Bad Axe 2: 4GB with >DDR2-800Mhz possible?

[GPSeek]

GP: My main concern is running 4GB at DDR2-1000 and above
on Bad Axe 2, 64bitOS will not help with that for sure

I can run my crucial sticks at 500MHz (i.e. ddr1000) on BX2 with a 4:5 ration without any problem.

However, I don't like the latency with 4:5 because the timing is not as tight as 1:1.

I'm not a fan of memory Mhz but I do care more about latency.
