Will it run 8? I do not see that anywhere...

What does it max at?
 
We've been through this ad nauseum in the last few weeks (including a $325 hit to my wallet for 2x4 gb SO-DIMMs). The MPB can take 8 gb of RAM, but it slows down dramatically. Six gigs works perfectly. Santa Rosa can take 8 gigs. The consensus seems to be that Leopard on a Mac Pro is somehow different at memory management than Leopard that is installed on a MacBook Pro. Probably has to do with machine identification during installation (i.e., different OS modules are installed). In addition, 64-bit Vista uses 8 gb just fine on a MBP under Boot Camp. Ain't the hardware, folks.

Mac Pros run OSX with 8 gb of ram fine unless the OS recognises its on a Macbook Pro and limits it Leopard shouldnt be the problem.

Huh...?

OS X supports much, much more than 8GB RAM...just look at Mac Pros... ;)

It might be a firmware thing, though... or just lack of larger RAM chips at time of spec'ing...

No its not, and with snow leopard we can have up to 16 TB of ram, enough for the next year or two i suppose;)

wrong! it's usually the chipset that limits the amount of RAM the system can use. OS X can support much more than 8Gb.
