Memory upgrade on iMac 20" Early 2008

I actually have 2 questions:
1) My iMac is running slow with CS6 installed and I need to upgrade memory. My iMac, Early 2008 with 2GB of memory, runs on iOS 10.9.5. Replace both slots with 2GB each or to replace one slot with 2GB makes much difference? I think DDR2 SDRAM SO-Dimm 800MHz is what I need. Does it matter what brand? Will this Dell brand works: Dell - Memory - 2GB - SO DIMM 200-pin - 800 MHz/PC2-6400 - unbuffered - non-ECC? It's the cheapest on Amazon. Or other recommendations?
2) I was set up with Mac and Window partitions. I seldom use Window. How can I combine the partitions to just Mac? I'm wasting 35GB of memory in an unused Window partitions.
Thank you.

posting on a mac forum would get you more help.

Cinema Display 27" with iMac 24" Early 2008

I want to connect my Cinema Display 27" to an iMac 24" Early 2008. I recently bought two adapters, one from Mini DisplayPort to DisplayPort and another one from DisplayPort to Mini-DVI. Unfortunately they won't work together. Before I continue buying more adapters I wanted to ask here, if anyone has any experience with this combination and can recommend working adapters to me. Thanks in advance.

I've seen offers on the web for services which will replace one graphics card for another in an iMac. You pay for the hardware and the service, and the service... ain't cheap... because it's not a trivial operation. I would never spend the money to have this done, because there will still be no certainty that things won't go kah-blooey later.
I sympathize. The iMac I'm currently using blew out its logic board two years into its three-year AppleCare warranty. It was replaced at no cost to me, of course, but as you pointed out in the case of your iMac, this was a well-known issue. And if it were to happen now, I'd be SOL because my iMac is now almost a full year out of its warranty.
On the other hand, I've held onto this iMac as my main desktop for a long time, much longer than I have for any computer in the past. 3-4 years is a good long time for a mostly-not-upgradeable all-in-one machine so I won't shed too many tears if that problem repeats (although of course I hope it doesn't). You've gotten three years plus out of your iMac, and while it might be tempting to pay for a repair, it might be better to just yank the resellable components (hard drive, RAM, etc.) and purchase a replacement Mac.
If you decide to go for the repair, you might find a sympathetic ear at your local Apple Store, if you come armed with some evidence that this component commonly fails and remain polite but firm. If you're lucky, they'll do the repair at no cost. Hope for the best, but expect nothing.

How can I make a recovery disk for an imac 24 " early 2008 to April 2009 or connect via thunderbolt to another imac

You will only know about the hard drive when you try to access it in TDM from your other computer. If you cannot boot into TDM mode or if the drive does not appear on the new computer's Desktop then it is likely bad.
What you are thinking about as a recovery disk is the Recovery HD normally created when you install Lion or later on the computer. You boot from it as follows:
Boot Using Command+R keys:
1. Restart the computer.
2. Immediately after the chime press and hold down the
"COMMAND" and the "R" keys together.
3. Release the keys when the Utilities Menu appears.

Hi gillian1981,
Thanks for visiting Apple Support Communities.
If you are seeing a recurring kernel panic on your iMac, the information and steps in the article below can help troubleshoot the behavior:
Diagnosing a recurring kernel panic can be difficult. If you need help with this process, consider bringing your Mac to a Genius at an Apple Store or an Apple Authorized Service Provider for help. If you plan to visit an Apple Retail store, you can make a reservation (available in some countries only).
Tip: To help diagnose recurring kernel panics, record the date and time it occurs, and any information that appears with the kernel panic message.
Was the computer starting up, shutting down, or performing a particular task when the recurring kernel panic happened?
Is the kernel panic intermittent, or does it happen every time you do a certain thing? For example, were you playing a particular game, or printing at the time?
Does it occur only when a certain external device is connected, or a device is connected to a certain port?
Start with the troubleshooting steps in the section called "Isolate hardware or software as the cause of the issue."
OS X: When your computer spontaneously restarts or displays "Your computer restarted because of a problem."

Memory upgrade on iMac (Late 2006)

I want to upgrade the memory on my iMac (Late 2006). My present memory is 1GB 667 MHz DDR2 SDRAM. I am getting that information from the System Profiler. That (one) module is in one Memory Slot, and the other Memory Slot is empty.
The manual says the following:
+Your iMac comes with at least 1 GB of Double Data Rate 2 (DDR2) Synchronous+
+Dynamic Random Access (SDRAM) memory installed. You can add 1 or 2 gigabyte (GB)+
+memory modules for a maximum of 3 GB of memory. Memory modules must meet the+
+following specifications:+
+* Small Outline Dual Inline Memory Module (SO-DIMM) format+
+* 667 MHz, PC2-5300, DDR2 compliant (also referred to as DDR2 667)+
+* Unbuffered and unregistered+
And it also says the following:
+Your iMac has a top slot and a bottom memory slot. You can add a memory module to+
+the bottom slot and remove the memory module in the top slot to replace the+
+installed memory. You can add a 1 GB or 2 GB memory module for a maximum of 3 GB+
+of memory.+
I guess I should just do as Apple suggests and add a 2GB module to the other memory slot, to maximize the total memory in the computer at 3GB. But does anybody have any alternative experiences or suggestions? Should I perhaps add another 1GB module to the other Memory Slot so that they are both equal? Has anybody tried adding 2GB to each Memory Slot? What happens? It seems odd or unbalanced to have a 1GB module and a 2GB module as Apple suggests. Any opinions from people experienced in this would be welcome, and I thank you in advance.

Hi rosalarose
To check how much memory you have and your memory usage go to: Applications > Utilities > Activity Monitor and select System Memory.
Your problem sounds more like a Software problem with Safari than a Hardware issue with the Memory. Instead of piggybacking on someone else's thread you should post a New Topic of your own here or in the Safari section of the Forum with a more detailed explanation of your problem.

Memory upgrade on iMac G3 700, help with system crashes

I tried to do a memory upgrade on my iMac, so I bought two kingston 256 MB PC133 modules, but none will work, the system starts, but hangs in about two minutes after loading the desktop. I went back to use the older memory module wich is an spectek, but I need the upgrade, any ideas?
Thanks!
FedericoMG.
Ps: Sorry about my english... I'm from Argentina... :-P

Hi Federicomg
The iMac 700 G3 should have been supplied with 1 stick of 256mb ram. However which is the correct type i am not sure as the Apple specifications for this model state PC100 whereas my iMac G3 700 graphite was supplied with 256 MB PC133-333 SDRAM
http://support.apple.com/specs/imac/iMacSummer2001.html
Apple profiler from my iMac this is the original supplied RAM from Apple:-
DIMM0/J13: Size: 256 MB
Type: SDRAM
Speed: PC133-333
1) I would re-instal the original ram and open system profiler to see what type the ram is.
2) Keeping the original stick in place add another stick of the new ram and look again in profiler to see if its recognised and again try the second stick to see if there's a problem with one of the sticks.
I am currently running my iMac with a small upgrade of RAM and the additional RAM is 128MB of PC100 and i have noticed the performance improvement since adding the PC100 so it's working and i have suffered no ill effects doing this..

Memory Upgrade: 27" iMac, late 2009

Hey everyone,
Quite late to the game, but definitely should upgrade my imac's memory from the standard 4gb - However my mac doesn't show up in the shopping aides some of the manufacturers have on their homepages, so the subject is a bit shady.
Am I still able to track down the working hardware for this particular computer?
If so, any suggestions? Would these do?
Thanks!

I also have a late 2009 27" iMac installed 16 gigs of crucial memory, I ordered the mid 27" iMac memory running at Speed: 1333 MHz been running them without a problem for two an half years.
Here is the link. http://www.crucial.com/usa/en/compatible-memory-for/Apple/imac-2*8ghz-intel-quad -core-i5-%2827-inch---ddr3%29-mid-2010
I have Yosemite install running smooth with no issue. Now I'm waiting for Kodak printer driver update.

HD Upgrade in MacBook Pro (Early 2008 Model) Recommendations?

Hello,
I have a MacBook Pro (Early 2008 Model), with Snow Leopard 10.6.6 installed (will probably upgrade to Lion when it's released and stable). I want to upgrade the 200gb drive to something over 500gb. The two drives I am currently interested in are the:
1) Western Digital Scorpio Blue WD6400BEVT 640GB 5400 RPM 8MB Cache 2.5" SATA 3.0Gb/s Internal Notebook Hard Drive
2) Seagate Momentus ST9750420AS 750GB 7200 RPM 16MB Cache 2.5" SATA 3.0Gb/s Internal Notebook Hard Drive
However, I have read of people having problems (hard drive going to sleep, and beach-ball of death whenever you need to load an application or something, etc.) with the Western Digital Scorpio Blue drives in their MacBook Pros. I don't want to have to do a lot of tweaking, I just want to be able to install and go.
Anyone have any thoughts or recommendations on a hard drive to put in this laptop? Any success stories with Early 2008 model HD upgrades?
Thank you,
Jesse

I would go with the faster drive (Seagate 7200 RPM drive) as you will notice the difference in speed. I've got a Seagate Momentus 320 Gig (7200 RPM) that I put in my late 2007 MBP and have had no issues with it.
I seem to get more of a beachball from my Time Machine drive spinning up than I do from the internal drive. It is noticeable but tolerable.

Where can I find a cheap RAM upgrade compatible with an early 2008 macbook 2.1ghz so I can run lion?

Question says it all really. Looked on amazon at a few but am not sure if they will be compatible or not. Just looking for something cheap but which will get me up to date with lion as it requires at least 2Gb and I'm currently only running the standard 2x 512Mb that it came with. Thanks.

The model 4,1 (Early 2008) can use 6gb of 667mhz PC2-5300 RAM
These are good online stores for Mac compatible RAM
OWC http://eshop.macsales.com/shop/memory/MacBook/DDR2/ - Similar to DMS, they offer Mac tested RAM at very good prices.
Crucial Memory http://www.crucial.com/ - good place to buy RAM from all over the world. They also have an excellent memory selector that allows you to choose memory based on your computer's model
Data Memory Systems http://www.datamemorysystems.com/apple-memory.asp - another good, cheap place to buying RAM if you live in the U.S.
Macdimms.com - Specializes in supplying Mac compatible RAM at extremely competitive prices. Brands featured include Crucial, Samsung, Hynix, and Micron. All brands carry a lifetime warranty. Discounts offered to educational institutions and students, active and retired military, resellers, and government agencies.
Here are instructions on replacing RAM in a MacBook with a removable battery. http://homeoffice.consumerelectronicsnet.com/articles/viewarticle.jsp?id=44404
If you don’t have the tools to open up the MacBook OWC has a set for $5

Lion will require at least 2gb of RAM but really needs 4gb to run smoothly. Also Lion doesn't run any Power PC programs. To see if you have any Power PC programs go to the Apple in the upper left corner and select About This Mac, then click on More Info. When System Profiler comes up select Applications under Software. Then look under Kind to see if any of your applications are listed as Power PC. Universal and Intel will run under Lion.
Before Mac switched to Intel processors they used Power PC processors from 1994 to 2005. Power PC 601 through 604, G3, G4 and G5. Applications written for the Power PC processors need the application called Rosetta to run on Intel processors. This was part of the Operating System in 10.4 and 10.5 but was an optional install in 10.6. With 10.7 Lion Apple dropped all support for Power PC applications.

Locating drivers for Imac 24" (Early 2008) to work with Vista 32 bit

Hi all. I'm really having trouble with my Mac and was wondering if anyone has an alternative.
I have an Apple iMac "Core 2 Duo" 2.8 24-Inch (Early 2008) running OSX 10.5.8. I recently partition my hard disk using Bootcamp and installed Windows Vista 32 bit.
This is where the problem starts. I misplaced the driver DVD's that came with the mac and i am in dire need of the drivers especially for the video card (ATI Radeon HD 2600 pro). I was able to download the drivers for the video card but, anytime i try to install or play a game for example, Call of Duty 4: Modern Warfare it always give me a error that no drivers were found and the game crashes.
Has anyone else encountered this problem?
Does the Apple website provide drivers for Imac 24" drivers for Windows Vista 32 bit?

Patrick,
Welcome to Apple Discussions.
You will either need to find your install discs that came with the computer or contact Apple and they will replace them for a nominal charge.
Going forward keep these and other original installation media in a safe place.

Very Low Sound Volume in Windows 7 - Bootcamp on 20" iMac from early 2008

Hi everyone,
I installed Windows 7 RC (build 7100 - 32 Bit version) using bootcamp on my iMac bought in early 2008 (2Gb Ram - 2.67 GHz).
The entire installation went well with no glitch or issues at all and I ran the bootcamp setup in Windows 7 to install the drivers. The problem I'm having is that the sound volume is extremely low in Windows 7. I can barely hear it when I turn the volume up to the max. I don't have volume problems in Leopard - only in Windows 7.
I also tried to install the RealTek Vista driver from my Leopard disk but still the same problem. As anyone run into the same problem? Any suggestions
Thanks!

i want to tell you my problem and my solution.
i have a late model macbook pro i installed windows7 rtm version x64.
and i always had windows on my mac (older models) with everthing working properly.
i did't have sound on my windows7 os. i tried everything form every forum.
they all had some problems my problem was that windows7 installed the driver by itself. but that my output was only 50% and i heard nothing.
everybody (including apple) say that you need the realtek/sigmatel driver
from the apple dvds or from the realtek site.
and i tried every version of the drivers (i have a lot of old apple cds)
but still no sound. windows 7 said drivers installed correctly.
installed.
High Definition Sound device or something like thad.
but now the solution.
i tried to install windows vista.
vista said drivers. installed (without apple drivers installed)
the driver name was:
Cirrus Logic CS4206a (ab75)
and these drivers are also on the apple dvds.(cirrus.zip)
so i installed windows 7 again.
and installed this driver first. then started bootcamp. drivers like normally.
everything now works perfect.

Memory upgrade on iMac 27 late 2009

Hello,
I have an iMac 27 late 2009 with 4GB memory 2x2. I'm thinking to upgrade on 8GB but I want to ask you before I do something. First question is if I can buy one memory 1x4 GB and install on iMac will it work good with other two memories or they have to be all the same, and second question is what type of memory you suggest yo buy?

Is yours one of these:
http://support.apple.com/kb/SP576
If so, these are the RAM specs:
4GB (two 2GB SO-DIMMs) of 1066MHz DDR3 SDRAM; four SO-DIMM slots support up to 16GB
You have two empty slots; I've heard both that it does not matter if you only put one module in, but also that it is better to put equal size pairs in - if you have any doubt, stop by an Apple store and ask.
There have been numerous posts here that there are problems with 16 GB, so I would advise to go as high as a total of 12 GB; that would mean you add two 4 GB modules at most.
As for brands, these are usually recommended here: Crucial, Samsung, or OWC (macsales.com) - but not their cheaper brand (NuRam), only the OWC brand. iMacs are finicky with RAM, so only buy top quality from a reputable vendor with a lifetime warranty.

Memory upgrade on iMac bought in 12/2007

Hi everybody,
I bought an Imac 3 and 1/2 years ago. I wanted to upgrade it to Mac OsX Lion, but since it has on 1 MB of memory it's impossible as Mac OsX Lion requires at least 2MB. Do you know if it would be possible to add some memory?
Thnk you.

Hi Federicomg
The iMac 700 G3 should have been supplied with 1 stick of 256mb ram. However which is the correct type i am not sure as the Apple specifications for this model state PC100 whereas my iMac G3 700 graphite was supplied with 256 MB PC133-333 SDRAM
http://support.apple.com/specs/imac/iMacSummer2001.html
Apple profiler from my iMac this is the original supplied RAM from Apple:-
DIMM0/J13: Size: 256 MB
Type: SDRAM
Speed: PC133-333
1) I would re-instal the original ram and open system profiler to see what type the ram is.
2) Keeping the original stick in place add another stick of the new ram and look again in profiler to see if its recognised and again try the second stick to see if there's a problem with one of the sticks.
I am currently running my iMac with a small upgrade of RAM and the additional RAM is 128MB of PC100 and i have noticed the performance improvement since adding the PC100 so it's working and i have suffered no ill effects doing this..

Question about Memory Upgrade for iMac G3/350 - Slot Loading

I was thinking of upgrading my memory and found this on eBay
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=350070149602
The auction says that it won't work in an apple computer but it looks like it should. Any help would be appreciated.
Thanks,
James S.

I agree with Richard; if the seller says it won't work in a Mac, why bother? It's likely to be hi-density, which either won;t work or will show up in a Mac as only half its true size.
I've been hanging around these forums for nearly seven years and have seen a lot of tears shed over alleged Mac RAM bought on eBay. Your mileage may vary, but I get RAM for our 13 Macs for online venders who are Mac-savvy. They all work.

Recommended Hard Disk Upgrade for 4,1 (Early 2008) Macbook?

I've read so many disaster stories out there (primarily from Amazon.com reviews) about upgrading mac Hard Disks, I wanted to get a real recommendation.
I was hoping to get a 750GB or 1TB internal HD replacement, and probably stick with 5400RPM to save battery life.
Any recommendations?
The "disaster stories" I heard were issues of performance degradation, stalling (due to waiting for the disk to spin up every couple of minutes) and disk failure, all in relation to the fact that they were going into macs rather than PCs.
Any suggestions? What has worked well for you?
Thanks!

With a 7200rpm drive you might notice a slight decrease in battery time. I've put one in a Early 2006 Model 1,1 for my niece and she's had no problems with it.
To buy a hard drive try Newegg.com http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007605%2060000334 0&IsNodeId=1&name=7200%20RPM or OWC http://eshop.macsales.com/shop/hard-drives/2.5-Notebook/
