Hello Lee, Eric, Kevin and All, It is sometimes determined by third parties that it is possible to install and/or address more RAM than is specified by Apple. When trying to determine how much RAM can actually be installed and / or addressed, I personally like to reference Other World Computing at www.macsales.com. Below, I have pasted some of their information regarding maximum Macbook RAM. Note that this list includes both the white plastic models as well as the black plastic and aluminum unibody models that were manufactured for a couple of years. This list uses the "Model Identifier," which is the preferred reference point for determining the model you are working with. The model identifier can be found by going to the Apple Menu / About This Mac / More Information / Hardware Overview. If running Lion, you might need to click a button labeled "System Report" after you've clicked the More Information button. Your model identifier will be something like "Macbook5,1." Here's the list from OWC.
MacBook1,1 (All) - Install/use up to 2.0GB total memory MacBook2,1 (All) - Install up to 4.0GB total memory, uses up to 3.0GB. Note: Although limited to physically utilizing a maximum of 3GB, there is a performance benefit due to 128 Bit addressing when 4GB( 2GB x 2 Matched set) is installed. MacBook3,1 (All) - Install/use up to 4.0GB total memory MacBook4,1 (All) - Install/use up to 6.0GB total memory MacBook5,1 (All) OWC tested to support Maximum Memory of 8.0GB. NOTE: these models require the most current EFI version as well as Mac OS X v10.6.6. MacBook5,2 **2.0GHz Model Only** Install/uses up to 6.0GB total memory MacBook5,2 **2.13GHz Model Only** Apple factory specification maximum 4.0GB, OWC tested to support 6.0GB maximum RAM. MacBook6,1, MacBook6,2 & MacBook 7,1 (All): OWC tested to support Maximum Memory of 8.0GB: HTH, Bryan On Aug 12, 2011, at 9:04 AM, Corman, Lee (OFB-LV) wrote: > Even the info that came with the white macbook stated it could only hold > 4gb. <--- Mac Access At Mac Access Dot Net ---> To reply to this post, please address your message to mac-access@mac-access.net You can find a monthly formatted archive of all messages posted to the Mac-Access forum at the following URL: <http://mail.tft-bbs.co.uk/pipermail/mac-access/index.html> The Mac-Access mailing list is guaranteed malware, spyware, Trojan, virus and worm-free!
