800 MHz RAM in new MacBook Pro?

[ravenvii]

I know they come with 667 MHz RAM. But if you get, and subsequently stick in, 800 MHz RAM, will it run at 800 MHz, or be throttled back to 667 MHz?

Someone has said here that it's a limitation in the Santa Rosa chipset and so it's limited to DDR2 speeds.
Not sure if it's true, though.

It will be throttled back to 667mhz.

That's a good question, I'm sure a tech website will try it out soon enough.

so-dimm ddr2 will work at 800 MHz, the only problem is there is none

But why? The chipset is 800Mhz.

But why? The chipset is 800Mhz.

The front side bus is 800MHz. The memory controller only supports up to 667Mhz.

I thought it might just be Apple being cheap with their RAM, but that makes sense.

But why? The chipset is 800Mhz.CPU FSB is 800MHz but chipset specs says 667MHz DDR2 for memory.

But its dual channel still. So maybe it isn't that bad?

Well, there you go.

Thanks guys. Guess I can get rid of RAM upgrades from my budgeting. 2 GB is plenty for me for the time being.
