L2 Cache: Says 2MB but apple site says 4MB: Anyone know why the discrepancy?

The laptops on Apple's website are the newer ones...they are Intel Core 2 Duo with slightly different specifications.

4 gig is advertised, but after OS overhead, etc., there is only 2.8 gig or so available.

The 64gb is now $299.00 at the Apple store and Apple store online. The 32gb is $249.00.

No storage device is exactly as its labeled. Whether it is a 32/64 or a 16GB device the actually actual amount of space will often be smaller that it is labeled.

It appears that model uses the same memory specs. Check your hardware manual to be sure.I found some information on Apple's web site. http://support.apple.com/kb/sp16You have to fill the slots in matched pairs of the same capacity, so make sure you purchase the correct sizes and amount. Your machine appears to be limited to 4 gb, so be aware of that.

I have the same question but it seems there's no way to configure Mac with 8G of memory. Hmmm..

Mine says 74.4G. I've got about half of the space used, and I have quite a few files, photos, etc. on here.

Yeah, probably... 2 different file systems, but there is a way. See http://support.apple.com/kb/HT2518

I can't see where it says 2 oak but any time u see the words 1 gb by 2 usually means 2 one gig sticks if it says 2 gig on the one stick then it should be 2 gig

Mine upgraded to 10.10.2 just fine, but I had to add some extra RAM to get it to run decently. This one is NOT "User Upgradable", so you'll have to find an Apple store to handle it, but boosting it to 8 Gig only cost an extra $99.

It's because those are 1000MB Gigabytes instead of the 1024MB Gibibytes Windows use to measure the size, Those can also be called Gigabytes, hence the confusion. If you plug it on a mac it will say it's 30GB, but the file sizes will also seem bigger so no additional data can be stored

Because some of the space is needed by the controller for SSD wear and caching. 120GB = 128GB, 240GB = 256GB, etc. The manufacturers mentioning the lower capacity aren't lying to you. The ones that say the larger capacity will say ~120GB Usable Capacity somewhere. Hope this helps! More info: http://forums.macrumors.com/showthread.php?t=1371468

According to Wikipedia, 4 GB is supported by Apple but you can put in 8 GB. I upgraded to 4 GB.

all i did was. i had (1) 512mb and added (1gb) to the other slot works for me but the best way to do that is get 2i have 1.5 gb now. computers work by the power of 2 -- so if you have 128+ 128 =256 or 256+256 =512512+512=1gb not all computers are picky some time you can like me 512+1gb and it works but other computers some time the power of 2 is the way you have to go

I would expect you have more room to cache so more applications will run raster. But 32GB will run a lot of applications plus the OS. Not sure you are getting anything out of it. People rarely run that much at one time. On the other hand, its only $45 - which is not that much more. You could partition it in half and make better use of the 45GB that you are not using for caching. I would play around with it and see if 45GB gives you any decreased performance. If it doesn't, use the other 45GB for something else. Cheers!

That is normal. The system reserves a portion for "operating overhead." Only the difference is available.I have 4 gb installed, 2 x 2; only 3.0 is available.

I never checked, as they were bad to begin with. I had to return them because one was registering 2GB and the other 4GB, instead of 8GB each (as was advertized). I would not recommend.
