bauhaus Posted May 16, 2009 Share Posted May 16, 2009 Some months ago a friend told me that the Santa Rosa Macbooks can handle up to 6gb RAM (Originally it was said that the maximun was 4gb). I remembered some days ago thinking about ways to extend the life of my machine (Im planning to stick with this little fella for years, it works great, I dont need more) and started looking for references about this. So far I got these: http://lowendmac.com/macbookpro/15in-macbo...-june-2007.html http://eshop.macsales.com/item/Other%20Wor...g/5300DDR2S6GP/ These confirm what my friend said, still I dont want to spend the money just to find it is not true. Anyone can confirm this is possible? I plan to upgrade the ram to the maximun possible thinking about the future: Snow Leopard, the next Adobe suite for OS X since it will be 64bits, etc. However my current setup has 4gb obviously in dual channel. What do you think? Link to comment Share on other sites More sharing options...

+StevoFC MVC Posted May 16, 2009 MVC Share Posted May 16, 2009 My iMac does 4gb max. I'm pretty sure up until recently the only thing that could take more than 4gb was the Mac Pro. Link to comment Share on other sites More sharing options...
Vice Posted May 16, 2009 Share Posted May 16, 2009 It's true it will do 6GB with a 4GB and a 2GB DIMM. However there are some issues when you go over 4GB utilization within the operating system. Some users report that it works fine others that they get kernel panics or weird behavior. What you should do is get the RAM from a place that will accept it back within 16 days of Purchase so you can try it. If it doesn't work just send it back.

mattmatik Posted May 16, 2009 Share Posted May 16, 2009 For Penryn users, such as myself, 6GB works fine. Going to 8GB is where things get a little testy. For Santa Rosa MBPs, I would do as Vice suggested and try it with a place where you can return it without hassle. I've heard for the most part it will work. This could be cleared up with Snow Leopard. If you can hold off until 10.6 releases, I would do so. Link to comment Share on other sites More sharing options...

Right now Leopard is happy with 4gb. Link to comment Share on other sites More sharing options...
Phalesafe Posted May 17, 2009 Share Posted May 17, 2009 Wow did not know this, 6gb would help a lot running multiple VMs lol. Link to comment Share on other sites More sharing options...
MrA Posted May 27, 2009 Share Posted May 27, 2009 I wouldn't go for the 6GiB. According to Intel's datasheet on the PM965 chipset, it only supports 4GiB of RAM (page 12, Mobile Intel 965 Express Chipset Family). Link to comment Share on other sites More sharing options...
