  Apple Firmware Update Allows 8GB in Late 2008/ Early 2009 MacBook5,1 and MacBookPro5,1 Models

  The Late '08, Early '09 MacBook and Macbook Pro models initially were introduced with a 4GB maximum RAM capacity. Through firmware updates and RAM technology progress we have been able to offer 6GB maximum via ONE 2GB and ONE 4GB module that performs quite nicely. Now we have another advance to announce for these models. With the latest Apple firmware update along with Snow Leopard 10.6.6 or higher we can now offer support for 8GB via a pair of 4GB DDR3-1066 SODIMM modules. BOTH Snow Leopard 10.6.6 and latest firmware update are required for the 8GB support. The requirements are as follows:

  • MacBooks with Model Identifiers MacBook5,1 MUST have Boot ROM version MB51.007D.B03. If your MacBook5,1 shows a lower version then you will need this: MacBook EFI Firmware Update 1.4

  • MacBook Pros with Model Identifiers MacBookPro5,1 MUST have Boot ROM version MBP51.007E.B05. If your MacBookPro5,1 shows a lower version then you will need this: MacBook Pro EFI Firmware Update 1.8

  Once you have updated and verified your Boot ROM is correct then make certain your Operating System is updated to at least OSX 10.6.6 , Snow Leopard is mandatory along with the firmware update for the 8GB system support.

  These updates apply ONLY to:

  • MacBook 13.3" 2.0GHz and 2.4GHz with Model Identifier MacBook5,1

  • MacBook Pro 15" 2.4GHz , 2.53GHz , 2.8GHz with Model Identifier MacBookPro5,1

  Look in your "Profiler" to identify your Boot ROM firmware version... Go to your ABOUT THIS MAC...then...MORE INFO and look for this:
