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.
View 6 RepliesHow 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.
View 7 Replies View RelatedI 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.
I have those sticks for my psp and the work great. PS3 sees them perfectly and the old pc I had, but for some reason my brand new imac doesn't see the memory stick I put in.
Am I putting it in the wrong way or do I need to buy something extra to get them to work on my mac?
Last night Lloyd Chambers of [URL] tweaked his DigLloydTools app (DLT) that we use to test memory throughput. It's now more accurate. The bad news is that it showed that when we put 8 sticks of memory in the 8-core 2.26GHz Nehalem, our throughput for memory read/write (memmove) dropped by 1/3. It turns a triple channel memory bus into a dual channel memory bus.
Specifically, in our test, the combined read/write throughput dropped from 9261MB/s to 6195MB/s when we went from 6x2GB to 8x2GB configuration.
Now, don't panic. That doesn't necessarily affect real world app performance unless the particular app you are running is saturating the memory bus. Which apps saturate? I don't know yet. I'm running our complete real world test suite including Pro Apps and 3D Games in both the 12G and 16G config. If I find anything that's significantly slowed by the 8x2G config, I'll post it here as well as on Bare Feats.
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?
View 4 Replies View RelatedI 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.
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 have three 16gb USB memory sticks that don't work correctly with Snow Leopard. Disk Utility is will only format them in FAT32 format and I'm unable to successfully copy files to and from the sticks.
They work perfectly fine under Windows in Boot Camp and also on my Windows based laptop. Sadly, I purchased them after I had installed Snow Leopard and I don't have access to another Mac with an earlier copy of Mac OS X to test them.
Is this most likely a Snow Leopard anomaly do you think or is it just that these sticks are not OS X compatible?
How many memory slots does the iMac 21.5-inch:2.5 GHZ base model have 2 or 4? Â

I am trying to free up memory on my MacBook. I only have 3.25 GB left and I have to Software Update and I want to download some things from iTunes. I'm trying to free up some space so I can do those things but how would I? I need to use all the applications that I have on my computer, and I need all the documents that I have on my computer. So how would I clear up some space on my computer? I've used Clean My Mac and other computer cleaning stuff too.

I've had no issues with data backup on my external hard drive since I got my iMac over a year ago. There was always plenty of space to make daily backups and last time I looked my data was backed up from about January.
Yesterday my backup failed for the first time. The volume saved to disk is 223GB and the computer says there's not enough free memory for further backups (only about 9.5GB left). Going into Time Machine I can see I've lost all my backups before yesterday lunchtime.
I've been trying to identify what I might have done to cause this and the only thing I can come up with is data capture overload during the importing of video from a camcorder into iMovie and/or Final Cut Express. Is it possible there are stray files left over from my video editing that are clogging up my system? I've checked out my Final Cut Express Documents files but nothing here seems to add up to the huge amount of data which seems to be causing this problem. If this isn't it then I don't know where all this extra data has come from... How can I find out where this extra data is which is preventing Time Machine from backing up?
Is it possible there is some problem with Time Machine configuration? Right now the configuration window reads this:
Every time I use my MBP alum a lots and after I close everything the machine gets and still very slow and I have to restart my Mac to refresh the memory.
My mac spec is MBP alumenuim 2G 2.2 .
I would like to notice I did not face this problem in the past with my old MBP 2007 4g 2.4ghz
So anyway I could free the memory or something instead of restarting the machine
what is the best way to free up memory easily? I have a fairly typical makeup of iTunes music, iMovie, iPhoto files, which is best to attack?

If I delete a file from a memory stick- it does not free space. This is because the item has been moved to the trash and it hasn't been permanently deleted. If I want to free the space I need to empty my trash. If I don't want to empty my trash how can I delete a file from a memory stick to free space (permanently delete just 1 file)? Also (sort of linked) - how do I just delete 1 file from trash (empty just 1 file)? The reason I like to keep trash for a while just incase I need to restore a file, if I know I will not need to restore it, then I want to permanently delete just that file.
View 2 Replies View RelatedMy Laptop runs slow and often spins when I open the browser or other apps sometimes and found the load average to be less than and also about 300MB free memory, till I notice swap as 40MB/256MB on iStat.
Questions:
1. How do I find out what process is causing the swap? The top does not show swap, and the vm_stat does not show swap either like vmstat does.
2. In the memory what does the wired, Active, Inactive memory mean? The only value that makes sense is Free.
I just experienced something totally weird on my Snow Leopard. It starts suddenly dropping in the free memory (green) in my activity monitor with around 10 MB per second and the inactive (purple) memory grows. And it doesn't stop until it hits 10 free MB.

I don't know what the deal is. I'm trying to install 2 sticks of 2GB into my 7,1 iMac, and the screw just won't turn. I'm using a standard Phillips head, and nothin' doin'. The screw is now starting to strip, so I guess I'm going to have to take this into the friggin' Apple Store just to have them open the thing.
