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 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 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 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 22 Replies View RelatedI 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?
my 2.66 ghz Quad Core Mac Pro has 6 gig's of memory. I always have several application's open at the same time. I've got Aperture 2 which is using 632 mb of memory but sometimes it goes over 1gb. Iphoto is using 300 mb, I've got firefox open, the New York Times Reader, Rhapsody's online player, Apple's email client, Itunes, etc. Do you guys think that 6gig's of memory is enough? Is more memory recommended? Would that 2 gig's of memory make a difference?

As you can see in the attachment, the apps I'm running aren't that big of a deal for the most part. This is a 2007 version 8-core Mac Pro, 8 GB RAM. I'm curious what happens to make the apps open bog down the computer like this? Just leaving everything running for days at a time?

View 3 Replies View RelatedAbout 6 months ago my Core Duo MBP shut off and then rebooted with loud post beeps. Everything is fine since except that it can only run with 1 stick of RAM in the lower slot, with both or just the upper filled it doesn't boot and the optical drive sounds like it cant start. My 1 year warranty is out and missed the 2 year upgrade. Also does anyone know if this model can run 1x 2GB of memory? I used to have 1.5GB (came with 1x 512MB and added 1GB) and now been running with just 1 gig and missing the performance albeit a positive is Snow Leopard is a lot more snappy on 1 gig than Leopard .

Buying a new iMac next month and was wondering if I can just order it with 4gb ram and add two 8gb sticks from OWC to obtain 12gb total?
View 5 Replies View RelatedI would like to upgrade the memory on my mac pro to 8gb (4 x 2gb) plus the original 2gb (2 x 1gb) that comes standard for a total of 10gb. I have looked on [URL] and the prices range from $198.99 to $799.99 for 8gb (4 x 2gb) kits. The Omni Technologies Optival is mighty tempting at $198.99 and I see that OWC has 8gb for $269. What do you recommend? Is Optival any good? The reason I an adding 8gb is for multi-tasking video/audio etc.

I see the numbers of everything from Core 2 Duo, to the slightly faster and cooler Core i3, to the supposedly faster core i5s and i7s. The benchmarks go up accordingly, but I found this does not always equate in a faster experience on most tasks.
Here's my experience so far on processor upgrade:
In one computer trade school re-certification class I am in, we are working with Windows Server 2003 on a Quad Xeon platform and it's incredibly slow.
But in a previous class we had the previous generation server edition on older Xeons, and while not fast, it was much better. On paper the newer multi-core Xeons should have made a difference, but could 2003 server software be that much more bloated than the previous Windows server edition that it would stall like that and make us wish we had the older setup?
I am going to try out the Adobe CS lab and put the new high end Dells to the test there and see if they work better than when we had an older CS version on older Xeon equipped Dells.
I don't know if this is something to do with Dell, or if Apple's increasing processor bumps/generations are going to similarly not make a difference in the speed things appear to go at, whether it's Adobe stuff, server stuff, or anything else that needs power.
I know somebody who plans on a Core 2 Duo, i5 or i7 MBP and I was wondering if the higher end processor is worth it in that case (iMovie being the main program of use).
Just curious as to how much of an improvement in performance I would see upgrading my system as it states above, since my 2006 machine is 3 years old and getting close to the end of my apple care, figured I would trade it in and upgrade.

What you say guys?
I know the same article is on main page
So the older Mac Pro's from 2008 have 2 2.8ghz Quad Core Intel Xeon processors, without hyperthreading, for a total of 8 cores, and the top of the line iMac has a Quar Core i7 2,8ghz with hyperthreading for a total of 8 (virtual) cores.
With the ghz being the same but less "real" cores, but probably newer CPU architecture, which CPU will actually be faster?
There's a lot of people wondering if the 13" MBPs would have been a lot better with a Core i3 processor, but everything has been just hangups over perceived old vs. new technology, and really the only thing the Core i3 adds is Hyper-Threading, but it doesn't have Turbo Boost, which helps the Core i5/i7s tremendously. Let's compare using Geekbench since it is cross-platform and one of the few available sources of info...
Core 2 Duo P8600 2.4GHz (~3362)
[URL]
vs.
Core i3 330m 2.13GHz (~3472)
[URL]
Core 2 Duo P8800 2.66GHz (~3700)
[URL]
vs.
Core i3 350m 2.26GHz (~3680)
[URL]
As you can see in both cases, the difference is pretty minimal indeed, and in single threaded applications, the C2D will easily outdo the Core i3 which lacks Turbo Boost and runs at lower clock rates.
And you get a 320M instead of Intel HD graphics with the new 13".
The Geekbench results from the old 15/17" to the new 15/17" are quite an order of magnitude better.
So unless people are expecting Core i5 processors in the 13", sticking to the C2D was actually a good decision, and given the differences between 2.4 and 2.53 isn't so large, one is far better buying the base 13" and then putting the money saved towards a good 7.2k HDD or SSD.
Note - I took averages of the 32-bit numbers and added them.
Note 2 - The C2D Pxxxx are 25W TDP processors, which are more efficient than the Core i3 which are 35W TDP processors. Less heat, better battery life from C2Ds.
I've been debating whether or not to upgrade my 3 year old 15" Macbook Pro that has a 2.2Ghz Core 2 Duo (Santa Rosa) to the new 13" 2.4Ghz Macbook Pro. FYI... My current system also has 4GB of RAM. Since both systems are Core 2 Duo, what kind of speed bump am I going to see? Would this be a substantial upgrade?
