I have 1 gig sticks in each of the 8 slots. I recently became aware that I am only accessing 6 gig. System profiler tells me all sticks are ok:
however, it is showing 512 sticks in slots J13, J14, J43, J44. (Again, they are in fact 1 gig sticks). Apple Hardware test implicates J14 and J44, with this error message: post/0/2048 DIMM3/J14, DIMM7/J44
By various means I have determined that my memory sticks are fine. I've swapped them out and tried them in various slots. The sticks in the bad slots work fine in other slots, etc etc. So I'm certain it isn't the RAM. Also, they are paired correctly.
I noticed on the Apple refurb site that Mac Pros from 2010 have either 4 or 8 memory slots. Is there an easy way to tell how many memory slots a computer will have? From what I have seen it looks like the quad core machines will have 4 slots while the eight core machines have eight slots. How many memory slots are in the hex core machines?
How many memory slots are in the 3.06 27 incher, and how many slots are taking up on the basic setup? If there are four slots, are all four slots filled with 1gb cards? Im curious because I ordered my iMac from my job here, and I also ordered 2gb of memory, thinking I can go from 4gb to 6gb of ram. I was going to order a 4gb card, but it was 200 euros at my job. If anything, I will order a couple of more 2gb cards, but that all depends on the number of slots available/open.
I have a 27" iMac and recently picked up the latest model MacBook. I also picked up a 4Gb (2x2) RAM. I placed the 4Gb in the MacBook and decided to place that 2GB from the MB in my iMac to boost it to 6GB.
Here is my question, did I place the RAM in the best slots, assuming there is such a thing as best slots. I remember from the old day of PC that there was a strict order for placement else I may not get the most out of the additional RAM. It does register as 6GB when I click on 'About This Mac'. Below is a diagram and screen shot to show exactly what I did.
The other day, I put more ram into 2 12-inch ibooks - my own 1.0 ghz, and my wife's 1.33 ghz (Yes, I know she has the faster machine. It means I'm the next to upgrade). Anyway, this is the first time I had opened them up at all and I saw something that confused me: I know that ibooks have only one available expansion slot for ram. That's what I saw on mine. But on my wife's, it looked like there was a second slot lower down, just below where I installed the ram, but missing the clips to hold the ram in place.
Is this in fact a second ram expansion slot, or is it just the shape of it that makes it appear to be one, or is it a second slot that is somehow unsupported or unable to be used? My guess is that it's just the shape of the hardware, and it only appears to be a second ram slot, but isn't really. But wouldn't it be sweet if there was in fact another usable slot in the ibook?
I am going to buy an Imac soon. Most likely the with 4 gig ram. I was just wondering how many memory slots does an 24 inch Imac have. Because I have 2 one gig ram sticks that I wanted to add to it and didnt know how many free slots it would have.
I get the message: the memory modules are installed in the recommended slots. Every time I restart my 2010 Mac Pro. I upgraded my memory with 3 x 2GB OWC memories. They are properly detected, and the system is working fine.
I have got a last generation mini with the GMA 950 graphics. What I am wondering is wether I can change the amount of memory that is used by the graphics?
Is there any way that the default stack memory limit for a user in Mac OS X Lion? You can you ulimit in Terminal.app to display information, you cannot change any values.
This is what is returned from ulimit when you try to change the stack memory size.
user@MacbookPro:~$ ulimit -s 81920
-bash: ulimit: stack size: cannot modify limit: Operation not permitted
Also, the default value is 8192KB which is approx. 8MB. That is weak, especially on my 2011 iMac with 16GB of RAM. I mainly do scientific programming on my Mac (Fortran). These programs usually require a larger stack size. One option is to allocate data to the heap but that is very slow.
A couple weeks back, we switched from exchange 2007 to exchange 2010.The only change required on the OSX mail client was to change the server address.I have two macbook pros, one is a 2GB early vintage intel, and the other a more recent 4GB model.Both of them are configured for access to the exchange server.Both are running 10.6.Once the change was made, both clients started using huge amounts of memory.This isn't a leak, as is reported in some Lion threads, because it eventually comes back down again.When you start the client, it might use about 150MB of RAM.After a while I have seen as much as 1.6GB of RAM usage on the 4GB machine.If you take the exchange account out of the mix (disable it in preferences) the client consistently stays at about 75MB of RAM.The peak isn't limited by the client as far as I can tell -- it basically uses up all free memory and drives the system completly nuts.Many of the applications no longer perform well once they are subjected to memory starvation, and this includes the mail client itself.
I am now running the activity window with Mail to see if I can spot a pattern, but in one case I watched Mail's memory usage grow in Activity Monitor with nothing in the Activity screen.I aso tried creating a new account instance on the 4GB machine, but without any cached data the behavior was far worse.It very quickly consumes the entire machine and doesn't seem to return to normal.I am firmly convinced this is a side effect of changing the exchange service or one of the exchange settings, if for no other reason than the behavior is new on two systems.It's still unforgivable for the Mail client to do this -- if it can consume all available memory then it needs to monitor itself and defer or break up what it is trying to do.I am a great fan of this mail client but this is so unusable that it might force me back to outlook running in a VM.
After deleting about 500 emails and going to erase deleted messages the memory available on my hard drive did not change. Should it? Do emails not take up any memory?
I have the Power Mac G5 Dual Processor 2.0 GHZ, with 3 GB of RAM, but I would like to upgrade but this model only has four slot, not 8. On the logic board, I can see little holes where the other 4 slots are meant to be, but obviously they aren't there. Is there any way to upgrade this G5 so it has 8 slots, rather than 4? I haven't found anything about this on the Apple Discussions, or MacRumors.
Someone else pointed out in another thread that on the 11" MBA with 4 GB, if you look in System Profiler under memory, the software says that there are two RAM slots. I can confirm that on my MBA. So:
1) Is the same true on the 13" with 4 GB RAM? 2) Has anyone published a tear down of a 4 GB model just to be absolutely sure that there is only one soldered RAM slot? (I know it's unlikely that a second one got crammed in there, but I'd just like to see the tear down picture)...
Ok, my problem is as the title states. Why is this happening? My motherboard had 8gb slots and is compatable with 8gb ram. I installed 8 dimms of this ram I bought from newegg: [URL]
Currently I have a GTX 285 in Slot 1, and a GT 120 in Slot 3. Slot 2 is the faster slot, which I would think would benefit the GT 120, but then it's closer to the GTX 285 that leads to overheating concerns. I'm going to run anything graphics intensive on the GTX 285-connected monitor, so any real drawback then to having the GT 120 in Slot 3?
I just purchased new ram to add to my 1.6hz G5, it has four dimm slots. I am aware of the pairing and slot requirements and believe that all is well there. I added the new ram to the two outside slots, these are numbered 2 and 3 by Apple and the original ram is in slots 0 and 1. The new ram was not recognized. I then swapped and put the new ram in slots 0 and 1, the old in 2 and 3, and the new ram was recognized but not the old ram. It appears that it does not recognize ram in slots 2 and 3, how do I get this to work?
Will the stock Mac Pro video card: NVIDIA GeForce 7300 GT, work in a PowerMac G5 Duallie 2.0 (mid 2004 model) with the pci-x slots? would a Cube G4 Rage 128 video card work in thePM G5? (I bought a G5 without a video card and I need to test it and find a cheap video card for it).

A G5 PPC Dual 2GHz that I am working on freelance for a client apppears only to have 4 RAM slots - could this be the case? I thought that from the 1st Generation onwards all G5s contained 8 slots.

I'm installing some firewire cards in a mac pro at my school but the Mojo that we're hooking up needs to be on it's own bus. Do certain pci slots share a bus together?
All of my used ID and password slots have turned black. I can't see what I am writing and evidently I am making mistakes because they are being rejected. How can I return these fill-in-the-blanks to white backround?

I have a iMac DV G3/500 (Special Edition) from summer 2000. Anyway, I am using Mac OS 10.2.8. Recently, my start up disk's memory has gone done from 1.2 GB available free space to 668MB (currently). I haven't saved anything on this disk so I can not understand why this memory has dissappeared. I have also had icons on the start up menu disappear. Could someone please tell me how I can restore the missing memory?
