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?

Mac Pro :: Memory Limit - Systems Recognize 4GB Modules?

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. My question is, has anyone successfully run larger configurations of memory, and will these systems recognize 4GB modules?

Laptops :: Macbook Pro Ram Upgrade - Removed New Ram Modules And Refitted The Old Ones?

Jan 8, 2010

I have a macbook pro of 8months old.The machine is fitted with 4gb ram, 2 x 2, but is able to be fitted with 8 gb.I bought 2 x 4gb of the same type of ram: 1067 MHz DDR3When it was fitted, the computer performed great, Autocad was flying.
Alas, after a few hours the computer went berserk and started to behave odd, refused to open a prog, refused to stop and finally refused to re-start.
When I removed the new ram modules and re-fitted the old ones, I found out that my hdd was not mountable. I did resolve the issue but lost some data in the process.

Mac Pro :: RAM Modules Must All Be Of The Same Manufacturing?

Jan 16, 2010

I want to know if the wool is being pulled over my eyes by OWC. The site says that their 4GB modules for a Mac Pro Intel Xeon Quad-Core 2.66MHz can only be put into the tower if the original Apple modules are first removed. Something makes me think that this is a salesman's bluff. Anyone know for sure? Sorry if an answer to this question has already been given elsewhere.

Mac Pro :: Can't The QPI Fetch From Any 3 Of The 4 Modules At Once

Jul 30, 2010

I know the newer Intel QPI processors have three main-memory channels, and I've seen much discussion and several complaints on these threads that Apple didn't expand their memory risers to squeeze in six DRAM sockets instead of four, so that the module count on each riser could be a multiple of 3. (And also that they should have done this for the 2009 Nehalems).

Here's my question: what kind of performance would I be losing and why if I got one of these new Westmere machines, discarded Apple's stock memory and replaced it with 4--rather than 3--OWC 4GB sticks? What I specifically don't understand is, can't the QPI fetch from any 3 of the 4 modules at once?

Mac :: RAM For 6 Core Westmere Pro In 3x1GB Modules

Oct 10, 2010

I've read many of the threads regarding RAM pricing and configurations for the 6-Core systems. I planned on ordering my Pro with 6Gb instead of the default 3GB, but my friend at Apple forgot when he placed the order. what I understand RAM module placement and type may significantly impact system performance for this platform. As I need to double the RAM, should I purchase 3x1GB modules to add or purchase 3x2GB models and sell the 3x1 that came with the system? Also, which is the best RAM retailer, OWC, Crucial, etc?

IMac :: Add 2 X 4gb Modules To Make It 12GB?

Nov 19, 2010

So my early 2010 iMac has 8gb of memory (4 x 2GB modules).I happen to have 2 spare 4gb modules that are from a MacBook pro of the same era - i.e they are DD3 1066Mhz and they will fit.So question is - if I take out two of the 2gb modules and replace them with 2 of the 4gb machines - will the machine work and will it see the full 12gb ( 2 x 2gb plus 2 x 4 gb)?

Mac Pro :: Installed 4GB RAM Modules - Computer Running Hot

Mar 29, 2008

I recently installed (4) - 4gb RAM modules and I'm worried that they may be running too hot. The image attached is from the machine just essentially sitting idle all day. Only 1gb of the 17gb are wired. When I do put the Mac to work, either through Handbrake or running Autocad through Fusion, the temp on module A1 reaches 173 degrees and the fan speed just about doubles.

PowerPC :: G4 RAM Modules And Error Code

May 4, 2009

I have an old PowerMac G4 (AGP Graphics), which has served me dutifully for a long time. However, I recently took all but 128mb of the ram out to temporarily use in other computers, and when I went to put the modules back in, basically none of them worked. Here's the deal: I have 2 256 modules, and when I put those in my computer, whether individually, together, or with other modules, I get this message on-screen and the computer does not boot: localhost:/ root# []. Similarly, I have 3 128mb sticks, but if I put more than one in the computer at a time, I get the same message. I'm thinking the computer may have some issue with more than 128mb of ram, but why all of a sudden? I don't really know anything about code or whatever the computer is trying to tell me.

Mac Mini :: Adding RAM To MacMini, Do Both RAM Modules Need To Match?

Aug 18, 2008

I have this 1.42GHz G4 Mac Mini that my mother uses for very basic stuff but still gets bogged down by skype videoconferencing or by having more than a couple of tabs open on the browser. I was thinking of adding some RAM to its original 512MB (DDR 3200 on 1 module).

I checked prices on Ebuyer and 1GB of DDR3200 SODIMM will set me back �26 while a DDR4200 module of the same capacity will cost �13. I was wondering if it would be OK to mix the 2 memory types and get 1.5GB, or if I should replace the original RAM completely.

OS X Server :: Unable To Use Calender Modules / Installing PHP Extensions

Jun 2, 2010

I have set our new XServe and have PHP running fine. However, I want to use the PHP calendar module/extension. This is a standard PHP module and can be found in the standard downloads from PHP.net. I tried to take the Linux approach of recompliling PHP with --enable-calendar however, this doesn't work as there is no compiler on the system.

Any ideas on how i can get the calander module to work? The only compiled versions of PHP I can find for the Mac don't include calendar.I'm Running OS X 10.4.7, PHP 4.4.1, Apache 1.3.33

IMac :: Adding Single 4GB Module To Existing Two 2GB Modules?

Apr 16, 2009

I've got a refurb 21.5" iMac 3.06GHz/4GB RAM/500GB HDD arriving soon.I believe it has two 2GB modules installed in two of the four memory slots, with two other slots unused. I have a few questions before I order more RAM for my machine.

Is it advisable to have ALL the RAM modules be of identical brand and size?Can other brands of RAM be added to the two empty slots as long as they are of the same specifications? Do RAM modules need to be added in pairs or is single ok?Can the added RAM modules be of any size (1GB, 2GB, or 4GB) and still work fine with the factory installed 2GB modules?

For example, would there be any performance problem by adding a single 4GB module to the existing two 2GB modules? Or would it be better to add two 2GB modules rather than a single 4GB module?

MacBook Pro :: Completely Restore To Factory?

I was wondering if there is anything else I can do to completely erase everything from my Unibody MacBook Pro? I usually do the 7 pass erase and install everything from factory but is there any other procedure I can follow to make sure my computer would be running at its best? I am not sure if it is me or not but my mac used to be faster when I bought it last year even after reinstalling everything from factory.
