Can I use the RAM from my new MacBook Pro in my 4-year-old MacBook Pro? I just bought an i7 MBP with 4GB RAM. I'm upgrading it to 8GB with this: http://www.crucial.com/store/mpartspecs.aspx?mtbpoid=8C4DD5E1A5CA7304

So I'll have the brand-new 4GB RAM I'm removing. Can I put it in my old MBP? Here are the specs of the old one:

Model Identifier: MacBookPro2,2
Processor Name: Intel Core 2 Duo
Processor Speed: 2.16 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 4 MB
Memory: 3 GB
Bus Speed: 667 MHz


Memory:
Memory Slots:
ECC: Disabled
BANK 0/DIMM0:
  Size: 2 GB
  Type: DDR2 SDRAM
  Speed: 667 MHz
  Status: OK
BANK 1/DIMM1:
  Size: 1 GB
  Type: DDR2 SDRAM
  Speed: 667 MHz
  Status: OK
No, you can't. The largest DIMMs the 2.2 will take are 2GB ones, and it can't address more than 3GB, so it's already maxed out: http://www.zdnet.com/blog/apple/inside-the-macbook-pros-3gb-ram-limitation/321
