or is that something the merom chips will bring? i assume current models don't since it seems the ram maxes out at 2gb. thx.

Yonah/Core Duo is 32 bit, Merom/Core 2 Duo is 64 bit.

What will 64-bit do for you in a laptop?

The current chipsets support 4GB RAM... you can't get DIMMs dense enough to exceed that anyway.

i have never seen/heard of a macbook with 4gb of ram... that would be fine though if it did support it. aren't there memory issues though when using more than 2gb of ram with a 32 bit processor?

obviously, what i am after is more ram. i do a lot of memory intensive things with windows virtualized... so the more ram the merrier.

The chipset in the MacBook (and all other Intel Macs) supports 4GB RAM. However Apple says the MacBook only supports 2GB, and I have yet to see confirmation that 2GB DIMMs work in the Intel Macs.

32-bit processors support 4GB RAM natively (assuming the chipset adds no limitations), and up to 64GB RAM with extensions like PAE (which creates a small performance penalty).
