IMac 24" Core 2 Duo 2.16GHz Memory issue

I just received a refurb iMac 24" Core 2 Duo 2.16GHz that came with a single 1GB memory module. I bought a 1GB module from Crucial. When both modules are installed, the computer doesn't chime and doesn't have any screen image nor does it boot. After doing some tests, I'm thinking that perhaps one of the slots is defective (bottom slot). Both modules work fine when installed on their own in the top slot. However, neither modules will allow the computer to POST when installed individually in the bottom slot. So this is definitely not a matched-pairs issue.
Has anybody seen this issue? Actually, if you're using one module, can you install it in either slots? None of the kb articles mention to populate a particular slot first when only using one module. I don't mind sending the computer in for service, however, it would nice if Apple were to send a functioning system back with the single 1GB module...

It sounds like you have pretty well worked thru the issue with that slot. Note: it will take more force to install a module for the first time into a new slot. If your sure that the module(s) were completely seated in that slot, I would have to agree with you that the slot is the problem. If you take it in to be looked at take both your modules with you for the tech to try. If you are sending it back don't send your new module, install the original module in the non-working slot, and let them sort it out.
Hope this helps you!

Macbook Pro Core Duo 2.16Ghz with 1GB+2GB memory module

Is it possible to install an 2gb modulle along with my 1gb module witch came standard with my macbook pro Core Duo 2.16Ghz?
Im thinking about the following modulle:
Kingston KTA-MB667/2G
(Any other suggestions?)
And just for my information is it possible to install 2x 2gb memory?
Thanks!

But i still have a few questions:
Is the 2gb modulle not supported or the total of 3gb
is not supported?
I want to know it absolutely 100% for sure becouse i
would love the 2gb addition. And i don't want a buy
something wrong :P
From what I have read in various forums a single 2GB module will work in the Core Duo machines. 3GB is not supported however. People who have tried adding 3GB (2GB +1GB) to a Core Duo report the computer would not boot.
I am not sure why you would want to use a single 2GB module though. Perhaps if you were wanting to upgrade to a Core 2 Duo later?
I would say if your going to try to use a single 2GB module understand the risks. i.e. I don't how much people actually tested for stability etc. other than to try it and say yeah it works. You do loose the dual-channel configuration for whatever that is worth.
I would make sure you purchase from a place that has a liberal return policy if your going to try it. Just in case your not happy with it.

IMac Intel Core Duo Hard Drive Replacement

I may need to replace my iMac (Intel Core Duo) HD soon; I'm wondering whether the Geek Squad does work on Macs. Also, is this something a person can do themselves with good directions, or is that risky. I've put in memory, but think the HD is probably a step up. I have everything backed up and would get all my stuff back on HD myself. Has anyone had experience with Mac repair here?
Solved!
Go to Solution.

Welcome, Selia!
We certainly do work on Macintosh computers. The criteria is: "Is the part user-serviceable?" We would need to sendthe unit in for upgrade to our repair center if it is not something Apple has in their DIY section of their website. This is toensure consistency and to avoid any issues if still under warranty. Typically only Mac Book laptop hard drives areserviceable in the store.
Either way, I recommend letting an Agent assist you in the store. Let us know if you need further answers.

Imac 17" core duo 1.83ghz broken display how to connect external display?

Hi there! I have a 2006 Imac 17" core duo and the screen broke by accident. The repair costs are extremely high and thus I was thinking about buying an external display and hooking it up to the imac. Firstly, would such a thing be possible, and if indeed possible how would one go about setting it up?

PowerMac G5 vs iMac Intel Core Duo

Hello, I currently have a PowerMac G5 Dual Core and am thinking of getting another computer. I have a question. In terms of performance, what is faster, the G5 (Dual) on the PowerMac or the Intel Core Duo on the iMac (running at the same speed).
And at the bottomline, what would be the machine that I want for gaming, publishing, and video editing? The PowerMac G5 (Dual) or the iMac with Intel.
Thanks for the assistance!! Have a good one.
P.S. Are there any plans of releasing a PowerMac with an Intel processor.
PowerMac G5 Mac OS X (10.4.6)
PowerMac G5 Mac OS X (10.4.6)

(Oh...right...sorry for mentioning that) Thanks for hte response!
Anyways, I just want a computer that will not be outdated for a while. I don't want to purchase the G5, and then months down the road, not see the G5 in production anymore.
One thing about the iMac I'm not too fond of is the lack of upgradibility (or so it seems so). Due to it's size, it would be very difficult for someone to upgrade it's internal components.
I will be purchasing either today evening of tommorow, and I want to know what will be my best choice for the future, the iMac Intel Core Duo or the PowerMac G5.
I always thought of the PowerMac G5 as a beast, and I still do, but some of the latest reviews and benchmark tests I have seen have said that the iMac (with Intel Core Duo) has performed very close to the PowerMac.

Quark 6.5 crashes when opening existing files on iMac Intel Core Duo

I just switched from a G4 titanium laptop to an Intel iMac and Quark works fine except when I try to open a file that I created on the laptop (same Quark 6.5). It crashes. I talked to Quark and they said that I need to open the files on a PC and resave (I don't have a PC or a friend with a PC and Quark not that I'd send them all my files even if I did). I've tried resaving and renaming files with no luck. I tried reinstalling both the operating system and Quark (both 6 and 6.5) with no luck. Has anybody else had this problem and found a work around? I want to sell my laptop but I can't until I know I can access the hundreds of client files I have there.
iMac Intel Core Duo Mac OS X (10.4.6)

Sorry I have no real experience with this, just a thought. Did you use migration assistant to move the old files over from your G4 to your Intel? And did you then perform a "Repair Disk Permissions" upon the entire hard drive from within Disk Utility's "First Aid" panel? (located at Applications>Utilities>Disk Utility)
If the file move still is causing you a problem afterwards, you could try and work around it by moving the files in a different way. As a test, create a small file on the G4 and then email it to yourself from the G4. Receive that message into the Intel and see if the Intel can then open the file from inside Mail. This might avoid any "bias" created during the move from old to new Mac.

My imac 17' core duo 1.8ghz a1173 freezes after about 1 minute of running

My imac 17" core duo 1.8ghz A1173 freezes after about 1 minute of running. I re-start the imac about a half a dozen times and it stays running and will re-start from the sleep mode and will continue to operate properly until I put it in sleep mode or it goes to sleep mode. If I turn it off, I must go through the same hassle. Advise/suggestions. Thanks.

IMac 17" Core Duo acting slower than it should-

My father has a first generation iMac 17" Core Duo. It should be really fast. (At least compared to my PMG4 MDD..) I think it is rather fast, but sometimes it is really slow. Spinning ball while changing application, spinning ball while opening applications, spinning ball while performing operations in applications.. However, when I checked last night, the CPU was typically used about 20-30%. About 5 MiB free RAM, and about 100 MiB inactive.
I get the impression that the computer is way faster before the Office suite is launched. Dad is always running Entourage, and often both Word and Excel as well.
Is it likely that this is the explaination? That the computer is slower when an Office app is running? MS states that it "should run well under Rosetta", but on the other hand, they're known for their BS.

Yes, that could very well be the problem, especially
if the computer only has 512 MB of RAM.
It has. Though I find it a little bit peculiar that it can have as much as 100+ MiB inactive RAM and still be slow.. I thought inactive RAM was RAM that could be re-used, like free?

IMac Intel Core Duo: Which Install DVD disks should I be looking for?

I have an iMac Intel Core Duo (2 Ghz, 20") model. This was sent to me from Apple as a replacement for my iMac G5 when it had problems a couple years ago. I just realized today that they did not send me OS install disks for it; I still have the iMac G5 install disks though.
What iMac install disks should be looking for to purchase? Are they specific to an Intel Core Duo? Would any iMac Intel installation disk work?
Thanks in advance.

You may be able to contact Apple and have them provide a replacement set for a nominal fee.
If it's the Core Duo white iMac from +early 2006+, it came with Tiger (10.4). Therefore, you can get install Leopard or the current Snow Leopard on it. You just need the standard retail disc.
Would any iMac Intel installation disk work?
Usually, installation discs that come with Macs (the grey ones) only work with that specific Mac model. A retail disc (the ones that are sold separately) will work with any supported Mac model.
There is another difference. The disc that is included with Macs also have additional bundled apps, such as the iLife suite. The original included disc for your iMac would have iLife '06, which is two versions old, so it may not be that much of a benefit today (iLife '09 is the current version).

External Drive Recommendations for iMovie '09 and iMac Intel Core Duo

I just got a new iMac Intel Core Duo, and loading up on 4 gig of Ram. Going to get an external drive to house video footage, and wondering if this model might be ok. I understand firewire is usually better than usb drives, but am looking at one that is USB 2.0 with of speeds up to 480 Mbps and transfer rates up to 1.5 Gbps. Claims it's almost twice as fast as FireWire 800.
Would this work well for iMovie, editing HD footage?
Thanks in advance for your replies.

LOVE this Fantom drive. Very quiet and an amazing price for 1TB with all interfaces.

EA Game (Harry Potter Deluxe Edition) will not play on iMac Intel Core Duo

I have repeatedly tried opening the EA/Aspyr Harry Potter games (Sorcerer's Stone and Chamber of Secrets) on my iMac intel core duo. It fails to open, with all attempts ending in a window that tells me it has failed and offering the option to cancel, retry, or report problem to Apple. This occurs with both discs/games. Is the software simply not advanced enough for the new iMac? Has anyone opened this at all?
PowerBook G4 Mac OS X (10.4.7)

They are both Aspyr ports of EA games. I've run both on my G4 Macs in the past but can't comment on their compatibility with the Intel processor.

Imac intel core duo 20" bug graphics

bonjour,
jespere que vous comprenez le francais
j'ai un imac intel core duo 2ghz, 1go de ram dd2 osx 10,4,9
j'ai un soucis quand je joue a world of warcraft, l'ecran se brouille, ne nombreux traits apparaissent, impossible de voir en fait le jeu correctement, obligé de faire un pomme+m et de revenir en full screen apres, et ca repart.
sachant que le jeu passe en full quality a 30fps a peu pres, j'ai essayé de tout baissé au niveau qualité et rien a faire.
je n'est pas eut le temps d'essayer d'autres jeux.
je n'est pas essayer en redemarrant sous windobe.
l'ordinateur est encore sous garantie.
dites moi tout ce que vous savez
merci d'avance.
a bientot.

Depends on how intensive you plan on getting with the iMac. For the most part, it should run pretty well. When the Adobe products become universal they should fly. I currently run all the same software plus Maya on my iMac G5 2.1 GHZ w/o a problem, so they should run just as well on the intel (more so when all apps become universal). I actually plan on selling the G5 and picking up the intel version so I can run boot camp and 3D Max as as well.

What is the latest operating system that I can install on my macmini 1,1? it has an intel core duo and 2gb memory.

Hey,
im thinking to expand my imac's total 1gb ram
and im really confused from what i've read about the memory amount a ram module
