6GB of RAM in a Macbook Pro?
I just learned that some folks are using 6 GB of RAM in MBPs that are supposed to only work with 4 GB. In my MBP (early 2008), I am running 2 2 GB chips. I am considering replacing one chip with a 4 GB chip. 8 GB does not work so well, apparently.
Here is the discussion link where I learned of it: 6GB in MacBook Pros; Yes it works. - 8GB... well... - Mac Forums I'm interested in having 2 more GB of RAM since I often use VMware Fusion to run XP, and I commonly have FCP, Compressor, and Photoshop open at once (OK, Firefox, too). There is disagreement as to whether the extra 2 GB of RAM is worth the hit you take not running in dual channel mode (two matched pairs are needed for dual channel). Assuming that the extra 2 GBs keep you from accessing your hard drive, I THINK there would be speed gains with the extra RAM. Any experiences out there? |
If you are looking for improvements in Final Cut you will see none. If I am not mistaken Final Cut only can use 4 gigs.

Guys, David could not have made it any clearer that his interest was in the extra RAM for running multiple apps simultaneously + a Windows XP virtual machine

Thanks for the replies.
So, if Chris and Pete are right and FCP can use up to 4 GB of RAM, then a MBP with 6 GB is going to run better. The OS has to use RAM, too. I'm not sure how much the OS needs, but I'm guessing the 2 extra GBs will help.
If I decide to go from 4 to 6, I will do some tests with 4 and then repeat them with 6. The rendering speed without the dual channel benefit of matching pairs is my main concern. Thanks again, DB |

has some tests on this. Bottom line is that not using two matched pairs is at most a very minor hit. |
