Macbook Pro Core i5 Memory Issues

The nitty gritty:

My i5 with 4GB of memory is using more memory to perform the same tasks as my Core Duo. They are the same clock speed.

In general, my laptop is constantly setting at nearly zero free memory, in spite of no major memory consuming applications running.

My wired and active memory add up to more than the real memory being used according to Activity Monitor! I just added up all the real memory usage and got about 1800MB, but Activity Monitor reports 2480MB as wired or active.

3.67GB of 4GB is currently used.

I know that OS X and other Unix systems always have a lot of inactive memory, but my old Core Duo did not do this.

Now, there's all the numbers, and here's the rest:

My laptop feels SLOW. In spite of low CPU usage, it is grinding way too much, and I think it's from having to free memory constantly, because I never have any free memory.

The i5 feels slower than my Core Duo, and that's insane because it benches nearly 20% faster.

I've ran all sorts of hardware tests, repairs and maintenance tools.. to no effect. Have also done SMC/PMU and RPAM resets.

Is anyone else experiencing this?

I feel the same the first time i used my mac.
My core 2-duo have some problems, i made a list of videos and text to go to apple store and reclame. Before doing that i let a cup of milk throw wy mac. Instead of problems i realy loved mac and became an user. i buyed onother. if i new what was comming ill never say bad thungs about the other.
my core i5 seems to work just much worse, crashes more, more slowly..i cant even put an tiff image in my archicad, it says have no memory!a few days my drive just stop working...i always say and ppl laugh at me"my core 2-duo was just much more better than this ****"...i dont understand..sometimes i wonder if that thing of virtual processors arent just a marketing lie
the worst thing is that my mom just used the guaranty to buy a thing because it have money in it because of a promotion and she lost the papper....i lost my guaranty and the insurance....and my mack have a small damage =S
Finally i see ppl that agree with me..core 2-duo was a machine....im so sad about this new macs

Hi Nick,


I have a 2.3ghz i5 MBP 13", and it always seems to be hogging ram and slowing down. I went in to my local Apple store, and Safari was hogging a WHOLE lot of ram (most of my 4 gigs) — they said to clear out the cache and start over, but even at the store it started to hog ram again. I now use Firefox, though its ram usage is still high.


Overall though, I have noticed that this computer is not as fast as one might think it should be. Anecdotal evidence, but I don't see much difference from this and older macbook Core 2 duos.


How did they finally determine it was your logic board? I still have a couple months left on my warranty.
