    I am planning on upgrading my ram for my Mac. Currently I have a 2.4GHz 4GB Ram (2x2 2GB Ram) 13' 250GB HD, I was wondering if i purchase one 4GB Ram can I put that in with one of the other 2GB Ram to make it 6GB in total?

    -Thanks a lot

    Yes, no problem. If you have matched pairs though (2x2, or 2x4) benchmarks will say that the performance is slightly better, but in practice I very much doubt that you'll ever notice that.

    Thanks, would there be a increase in speed/performance at the slightest?.

    Going from 4GB to 6GB would give you a boost if you were running low on memory. They extra memory will allow you to run more programs concurrently as well as it will keep them in inactive memory and load faster if you have extra ram. How is your current memory utilization as related to free or inactive memory? Typically if your page outs are high then more memory will help speed things up as you will probably swap less.

    what year MBP do you have? some are not compatible with 8GB RAM. please specify :)

    there will be a performance loss upgradaing to 6GB, and no performance increase going to 8GB (talking read/write speeds here etc).

    I have the latest 13.3 inch 2.4GHz 250GB 4GB Ram model, does this mean if i upgrade to 6GB there will be a performance lost?

    How is your MB performance/speed wise. Are you happy with the upgrade?

    If i do chose to upgrade from 4gb to 6gb, will there be a performance loss?

    ahh ok. there will be a slight performance loss due to them not being "paired". technical terms etc - not that you will notice unless you do synthetic benchmarks, on my iMac iwas about a 5% loss in performance.

    it doesnt appear as though you need any more memory - in Activity Monitor.app, what is your page ins/page outs/swap file size?

    Page Ins: 269.6MB
    Page Outs: 352.5MB
    Swap Used: 14.6MB

    *Note* I plan on installing office 08' will this change anything drastically? And how much of a performance loss be if i do go with a 2GB and 4GB (6GB Ram) upgrade, will it be significant?

    hey i was running a 2 gb and a 500 mb ddr2 ram in my macbook for 4 years =D haha worked very well with 2.5 gb of ram >_< lol i upgraded today to 2x2 with a total of 4 gb and i noticed a decent speed increase =D and i think the other guy meant that some computers are designed for a maximum amount of ram like mine for instance if i upgraded to 8 gb it would not perform better because it is designed for 4 gb so it would use 50% of it and just obsolete the rest >_< hehe but it should work swell =D

    ahh is that all. your RAM is hardly being pushed at all ;)

    you will see a 5%-10% loss in benchmarks, in the real world - you will not notice it.

    lol yea thats all. I bought this MBP a week ago (upgraded from white macbook 08 model) I want to make sure i don't slow down. I want to upgrade the ram to 6GB but there saying because they are not the same (2+4=6) there will be a slow down? should i go upto 8GB? and any tips on making more room on the HD. I already have all the apps (AppZapper, Onyx, iFreemem) i disabled dashboard and deleted unnecessary widgets/apps. Any aother advice to save room for the future?

    wow. you seem quite OCD about this - nothing wrong with that though of course. in all honesty, you dont really have to worry about much. make sure you have enough free HDD space and you will be fine. dont install apps that you wont require.

    the upgrade to 8GB RAM is *only* $227, is that too much for you?

    Judging by your posted usage, you really don't need to upgrade your RAM. If you don't use all 4 gigs, 6 or 8 won't get you anything more than you already have. Always remember, more RAM does not necessarily equal faster computer. It only does if you are maxing out your RAM and have a lot of page outs (writing memory to the hard drive) The stats you posted showed over 50% of your RAM free, so you should be good with 4GB. And to answer your question about office, that takes up very little memory, so don't worry about it.
