Windows 7 RTM x64 on Macbook (not pro)
So, I installed Windows 7 x64, figuring that Apple would allow me to install the 64 bit drivers on my Macbook. I was wrong.
When you insert the (snow) Leopard DVD, it gives you a message along the lines of “you don’t own an expensive enough Mac to use 64 bit Windows”. So, with a little fancy Googling, I found a workaround.
It is confirmed working with the Snow Leopard DVD also.
Open the start menu and type in “cmd”. Right click on the result and select run as administrator.
Then type in:
D:
cd “Boot Camp\Drivers\Apple”
msiexec /i BootCamp64.msi
There! If you have done everything correctly, you should be on your way to installing the 64 bit drivers!

Does the MacBook support more then 4GB? Last I checked it didn’t, and so the effort to run 64bit mode is pointless… you’re not going to becable address any memory that isn’t there or supported by the motherboard.
Technically, my macbook (aluminum) supports 6GB of memory. I really don’t think that x64 is worth it, but I figured I’d try it out because I have some extra licenses (from TechNet).
Besides, more and more apps are being released with 64-bit versions all of the time, and there really isn’t a downside to running it.
