As far as I know Santa Rosa will only support 667.

In any event though, the latencies of the higher clocked RAM completely wipes out the speed advantage. Any speed at 533 or faster performs about the same.

Especially considering the price difference on that Crucial chart. The DDR2-800 costs significantly more, which is a waste as it would downclock to DDR2-667 speeds anyway (if it even runs at all).

does HP offer the 800mhz RAM versions for sale on a customized dv9500t? if they do then isnt it some sort of misrepresentation of the product considering they know it will downclock?

I asked a rep about the speed of the ram for the dv9500t and he said it was clocked at 667mhz

I doubt they offer it on the CTO's, and it is not listed on HP Parts either. I don't even know why Crucial would list DDR2-800 for that machine.

Santa Rosa does not support DDR2 800Mhz RAM. It supports 800MHz FSB processors. The latest Intel chipset used in Santa Rosa based systems currently only support memory upto DDR2 667...

Take your pick. I prefer Crucual due to previous experience with them plus they are owned by micron and so use Micron memory chips but Kingston are also pretty good and in reality difference between the manufacturers has decreased and quality in general is pretty good amongst the manufacturers.
