Anyone running 6Gb of ram in their unibody macbooks? And if so, how stable is it when your using all of the 6gigs?
Thanks.
Thanks.

I'd also like to know this as i have the same macbook and thought it was limited to 4gb?
...unofficially, they support 6GB but then you'd lose dual channel speed (in favor of 2 more GB of RAM)... 4GB RAM chips are still very expensive... do you have 4 GB currently installed?
If you do, how many page outs does your activity monitor show?
If you're not showing many/any page outs, 6GB of RAM may be a waste of $$ for you...

I know there is a little loss of speed, but nothing that your really going to notice anyway. Also, I do not currently have 4Gb installed, but when I upgrade my ram Id rather do it all in one sweep, and just up it to 6 already.
I was wondering the same thing. The loss of the dual channel speed concerns me slightly, but does anyone have any knowledge of how that will affect the system? What kind of boosts will the system receive in 4GB vs 6GB? Even with the loss of the dual channel speed, is the 6GB still a better buy?
I was just reading a lil wiki on the site actually, I cant find it right now, but it was saying something about the system being able to do the equivalent of a software style dual channel mode. Which means that even though you dont have matched pairs, the system can still use some of the advantages that matched pairs would give you. I believe this means that if you were using, say, 6GB, (2GB+4GB), you would be able to have dual channel for the first 4GB of ram, after that, when the other 2GB were needed, you would not be able to have all the features of dual channel for that additional 2GB. I also read that the speed difference is not noticeable at all, and that if the need for that much ram is there, it outweighs having just 4GB with full dual channel support.
I just want someone who is currently using 6GB of ram to confirm this, and talk about how reliable the system is or isnt, with the 6Gigs installed.
Q: Do I have to use matched memory modules?
A: No. Modern laptop chipsets do asymmetric dual channel, which essentially gives you all the benefits of dual channel RAM with unmatched modules. There is a slight decrease in memory speed with unmatched modules, but it is on the order of a few percent and you will probably never notice it in real-world use.

...with the current prices on 4GB RAM modules, the benefits are probably outweighed by the cost to have a total of 6GB RAM in your MBP unless you have $$ to burn IMHOP...
Hello,
Where do you get the specs for an "old" macbook - like max memory?
I have a Macbook with a model identifier 5,2 and the text in the back of says 2007. It has 2GB now, but how do I know how much it can use?

Yea, I kind of get that thought sometimes too, but I may have to go for it. I probably wont buy for a little while, and hopefully they can come down in price a little bit first.
Lol..stupid me, I looked for that And i swore to myself that it was a single sodimm..****
...that would have been a hella deal if it was for a 1x4GB stick, even with the USD to CAD conversion

No doubt lol, I was super excited when I saw it. Too bad I jumped the gun a little bit.
Merry Christmas,
