MacBook :: Factory Memory Modules / Missing One Gigs Of Memory?

Oct 16, 2009

I have a Black MacBook (Early 2008). I think that I still have the factory standard RAM sticks (I bought the Mac used from a friend). I noticed today that I am running on only one gig of RAM even though I have two gigs of memory.

MacBook Pro :: Is It Advisable To Use Uneven Memory Modules

Jul 30, 2010

I am planning to upgrade the standard 4gb of on my April 2010 Macbook Pro (the basic 2.4ghz model) to 6gb.

Over on Crucial memory suppliers they advise using two identical modules, i.e. 2 4gb sticks rather than 1 2gb + 1 4gb.

Can anyone chip in on whether this is good advise or just them trying to make a few more bucks?

For my needs 6gb should be perfect, I have a desktop already with that amount, although to be fair the desktop is 3 * 2gb modules.

IMac :: Using 2 Or 3 Memory Modules?

Nov 18, 2009

While browsing around I've stumbled over a few references to things like "tri-channel memory" and such. From what I understand (not that good with these things) some computer architectures / CPUs are optimized for using 3 memory modules, and some for using pairs (2 or 4).

I just read some benchmark tests of the i7 with different memory configurations, and the 12Gb was is most cases on par or better than all the others when it came to performance, even better than the 16Gb one. Is the new iMac (i7) best suited to use 3 memory modules?

Mac Pro :: (8 Core) Memory Configuration - Four Modules

Jul 25, 2008

I bought a refurbished Mac Pro (8 core) from the apple store and added 4 Gb (2x2Gb) to the 2 Gb tht came installed. I am having a peculiar problem in seeing all four of the memory modules. The only setup that shows all 6 Gb of the memory is to have the modules in the following format: a) 2Gb modules on Riser A, positions 1 and 3 plus 1 Gb mods on Riser B positions 1 and 3; b) 2 Gb and 1 Gb mods on Riser A positions 1 and 3, respectively, and the same on Riser B.

When I put them in the logically (and aesthetically better) intuitive configuration of paired mods in positions 1 and 2 of each Riser, I can only see the modules that are in position 1 of each riser. Is this something expected in the new MacPros? Is there a disadvantage of keeping this configuration? I note that a memory installation video on line stated that the way memory is installed in the early 2008 Mac Pros has changed. Does this issue result from that change?

MacBook :: Start Up Disk Is Full / Even Though Yesterday I Deleted 1.5 Gigs Of Memory

Feb 3, 2012

Yesterday I deleted enough files to give myself at least 2 gigs of free memory and yet today when I opened up my macbook it tells me I have only 190MB left, and yet none of the files that I deleted remain on the computer, and my trash is completely empty.Does anyone know of any sort of 'Detox' kind of program or method to get the Macbook to reanalyse how much memory it really has left? It's done this before, but I haven't figured out a way to snap some sense back in the harddrive to remind it of the fact that it deleted those large files ages ago.

Dec 27, 2008

I'm in the process of upgrading the memory on my 1st gen Mac Pro. (2 x 3.0 Ghz Xeon). Apple publishes a memory max of 16GB., but I have seen references to these machines running more.

Applications :: Aperture 2 Using Too Much Memory / Should I Upgrade To 8 Gigs?

May 28, 2009

I'm trying out Aperture 2 for the first time, I always used Iphoto. I have imported my large library into Aperture. Activity Monitor says that Aperture takes up 1.3 gb of memory when being used and 600 mb when It's not being using it.

Is it normal for Aperture 2 to being using this much memory? Iphoto uses 350 mb of memory. My 2.66 Ghz Quad Core has 6 gig's of memory. I run aperture alongside Iphoto, Firefox, Itunes, New York Times reader, Rhapsody's flash player, etc.

OS X :: Adding Memory And Then Running The Memory Utility Application?

Mar 21, 2009

I just bought a early 2009 MAC Pro and it came with 3GB of RAM, I ordered 3 2GB sticks of memory to replace the 3 1GB sticks that I had in there from Kingston. I turned off the unit, I popped the little levers and pulled the memory out of slot 1, 2, 3 and then replaced the memory with the new Kingston in slot 1, 2, 3

One of the sticks in is not working at all and I get the RED LED light no matter what slot I move that chip to. So I am running on 2 of the new Kingston memory chips.

Can I mix the memory and add the 1GB into slot 3 and 4 with slot 1 and 2 full of 2GB chips?

Also how to I run the memory utility again? I went to /system/Library/CoreServices/ and then I see the program Memory Slot

How do I run this? I'm used to no spaces and I type ./then program name

OS X :: Memory Keep Disappearing Day By Day / 1 Giga Of Memory Left From 2 Giga

Apr 14, 2010

I'm new to mac and I've noticed that I can have 2 gigs of memory one day and the next I'm down to 24 or something!I've noticed that if I open a file in Itunes and then change the info that there are now 2 files in the finder, one with the old info and the new with the new metadata. Why does OS-X do that?!

Also, if I have 1 gig of memory left (out of 180 or so) why does it disappear to 0 if I open photoshop? I'm used to a PC running virtual memory and CPU but why does the Mac actually take away my available memory?I'm at my wits end here, it's been driving me up the wall for weeks!

MacBook Pro :: Upgrading RAM On Late 2006 From 2 Gigs To Maximum Of 3 Gigs

Jan 4, 2010

I'm looking into upgrading the RAM of a late 2006 MacBook Pro from 2 gigs to maximum of 3 gigs. Should I just get a 2 gig chip and replace one of the 1 gig chips with that, or would I be better off purchasing a pair of 2 gig chips and replacing both of the old 1 gig chips with them? So basicly I'm asking wether the RAM chips should be in identical pairs or does it matter?

MacBook Air :: Does SSD Really Need 4GB Of Memory

Jul 8, 2009

I am considering upgrading from my ~2 year old MBP to a 2.13 MBA Rev. C and have a question re: RAM performance: how does your MBA w/SSD perform once you have maxed out the 2GB of internal RAM and started swapping to the SSD?

The reason why I ask is that my current MBP had 2GB of RAM which would max out under my regular daily use (typically open is Mail, Entourage, Skype, Adium, iTunes, Keynote, Activity Monitor, and Safari with 10+ tabs open... don't ask). As you might expect, everything grinded to a halt once the MBP blew through the physical RAM and it started swapping to the HDD. A few months ago I upgraded to 4GB of RAM and everything ran smoother.

MacBook Pro :: Memory Hog - Gets Really Low

Apr 23, 2010

I've noticed in the past that after a few days of use, the free memory on my 2009 MBP gets really low. I notice this because when I get bored I snoop around the activity monitor - I actually don't notice any type of sluggishness. I'm simply inquiring about this. What I've done in the past is simply just reboot my system. This seems to work, but I just restarted my system last night, left it overnight and now according to activity monitor my free memory is at 12 mb! During the screenshot, I have Firefox with two tabs opened, iChat and iTunes.
