IMac iSight with bad onboard RAM

Hardware test is reporting that the onboard RAM on a 17" iMac G5 (iSight) is bad. It's out of warranty, and I'm happy enough dismantling it if I have to, so is there any way to remove/replace/disable the built in 512MB module?

Unlike some other iMacs the iMac G5 (iSight) has the 512MB soldered to the logic-board. Replacement is not possible except by replacing the entire logic-board at significant expense.
Are you actually suffering any issues with the iMac that caused you to run Hardware Test?

Problems with my old iMac 500MHz with 128MB of RAM

Ok guys...
Lucky for me I have a brand new intel pro duo iMac.. but I still have the urge to fix (or at least try to fix) my old mac.
Its an iMac 500MHz with 128MB of RAM running OSX 10.2.8 and its giving me tons of problems...
But theres one problem thats bugging me the most! For whatever reason I can't click and drag files! You'd think it would be the mouse... but the thing is that it registers a hold down click cause I can make a highlight box on the desktop, highlight text, ect.
Is there some known "you can drag files" problem with OSX? It doesnt sound like that big of a deal.. but it ***** when I cant drag files in or out of the trash... put apps in the application folder... ect.
Can anyone help me?
iMac 500MHz with 128MB of RAM Mac OS X (10.4.7)

Hello Vaseline,
Welcome to the discussions area. My first thought is that with your ram at 128 you are just about at minimum.. I would definately up the ram.
Secondly....look at this link and see the advice given by others. Go to the advice of dale which will lead to Dr Smokes link and follow his instructions

This may not be an exact solution but will help you get started....Good Luck with this problem and the new Mac.................Jim

Anyone Else Notice How Tempermental the iMac is with 3rd Party RAM?

I recently upgraded my 2007 iMac so Lion could run more smoothly by adding RAM from Crucial.
The machine worked fine for a few days then I started experiencing kernal panics. I suspected my new RAM wasn't seeded properly. The last straw was when I shut down the system to re-seed the RAM and turned it back on, the machine beeped three times at few second intervals (which indicates a problem with RAM) and would not power on.
I moved it to a different slot--still no joy. In an effort to just get the machine started, I tried other 3rd party RAM that was compatible with the iMac that I had lying around. Still no go as the machine would beep loudly and not power on.
I finally found some RAM I had taken out of my 2007 Macbook Pro when I upgraded it. It was the original RAM that had come with the Macbook Pro. It worked like a charm.
But I'd like to upgrade my RAM. Guess I'll have to take a trip to the Apple store and buy from there--much more expensive though.
Anyone else have issues with RAM?

Mac's are not tempermental with third party RAM however they are sensitive to the following RAM issues:
1. Incorrect RAM specifications. RAM specs must exactly meet Apple's specifications, period! Installing incorrect RAM will cause KPs.
2. Unseated RAM. Unseated RAM will cause problems.
3. Failed RAM, this is more unusual however it's possible to have a RAM DIMM be defective of fail at a later date.
The only third party RAM I would not recommend for your machine is Kingston Value brand, this has been troublesome. However if you use OWC or Crucial both are great vendors and sell RAM that works assuming 1, 2 and 3 above.

Upgrading Hard Disk iMac iSight

ALCON,
I bought a WD 500GB SATA drive yesterday and then spent a few hours yesterday ignoring Apple's caution about the only user upgradable part inside an iMac iSight G5 being the RAM. In short, they're right. After (eventually) opening the computer and getting under the screen to reveal the hard disk, there was no way to remove it without disassembling a whole lot more than I wanted because you can't get a screw driver/torz bit onto all of the screws holding the drive in without disassembling all kinds of stuff. Furthermore, getting to this point required me to tear open the protective lining inside the computer and I ended up pulling the isight mic wires loose from the top of the case. Last, even if you get further than I did, you'll have to contend with how to remove and hook up the temperature sender connected to the side of the OEM drive. The WD I bought does not appear to have the correct connection to make this work. So, hours later I successfully reassembled my iMac and it works fine...minus the mic. I took a couple of pictures for anyone interested. Send me an email to [email protected]
Jeff

Hello Jeff,
I bought a Seagate 160GB SATA hard drive, and looking to the installation instructions it seems that the drive does not have the screws holes and connectors located like in the instructions PDF manuel that I got from Apple. It seems so simple in the instructions ...
Where can I have a look at your pictures ??
Thanks in advance.

Slow Internet Connection on iMac G5 with Airport or Ehernet

I'm running 10.5.8 on a Power PC G5 iMac (ISight) with 2.5GB SDRAM and 40GB spare space on the hard disk. There's 2 ways I can connect to the internet:
Using Airport, where I get a max download speed of 3Mbps.
Using a Devolo powerline bridge where download speeds are also 3Mbps. The spec transfer rate of the Devolo device is 14 Mbps. All download speeds are measured using www.speedtest.net, and I have a 802.11g wireless router.
My ISP subscription is for 16 Mbps, which I can almost achieve on my iPad elsewhere in the house.
As a straight comparison test, I ran the speedtest on the iMac with a Windows XP machine right beside it. While the Windows machine returned a max download of 7Mbps, the same test at the same time on the iMac only recorded 2.5Mbps.
I have done all the ususl things: reset permissions, rebooted PRAM, reset the router, deleted all wireless connections from the iMac etc.
It therefore appears that, whichever means of connection is used, the iMac can only reach 3 Mbps. Is this something which could be a function of the age of the iMac (6 years) and its spec, or is there something I can do to improve the speed and return it to the higher levels I used to enjoy?

Hi Paul,
That really is a first...if you go over to the iPad discussions there are a lot of complaints about the iPads are so slow compared with the uers' Macs/PCs, etc. You must be the first person to say their iPad is faster than their iMac
It is very possible the issue is the age of the iMac, though it seems the speed is a little low for a machine connected by ethernet. I could understand the slower transfer rate on wireless since the older AirPort cards were much slower than today.
I don't have my 802.11 standard here right now, over at my daughter's house, but the transfer rates you quote for the service provider sound like the g-protocol limits in free-air. So the half-speed rate is not an unreasonable reduction.
When you say you used to enjoy higher transfer rates, was that with 10.5 or 10.4? Just curious, because improvements in OSs often carry along higher system overhead, also.

IMac 17" with isight RAM question

I want to expant RAM on my old iMac - iMac 17" with iSight, 1.9 GHz, introduced october 2005
Is this RAM module going to be compatible?
DDR2
*2 GB*
*533 MHz*
PC4300
1,8V
*240 pins*
*Cas Latency: 4*
My concern is if the certificate (PC4300) is going to be compatible. Apple website says that there should be certificate PC2 4200.
Thank you for your answer. Greeting from Czech Republic.

Welcome to Discussions - the specs for your memory are
iSight:
1. PC2-4200
2. unbuffered
3. nonparity
4. 240-pin
5. 533 MHz
but I think the 4300 would work, just make sure that you can return it if it doesn't and that you get a lifetime guarantee.

Problems with Installing 4GB RAM on mid 2007 iMac

I ordered 2 X 2GB sticks of PC2-5300 DDR2 SODIMM RAM for my Boss's mid 2007 iMac from Crucial.com. Well they arrived a few days later and today I have been trying to install them for a few hours now without any luck. I have installed new RAM about 5-6 times without any problems before on different MacBooks and iMacs. After this install I plugged back into the wall and hit the power button, the iMac made a little noise (internal noise) then nothing, just a blank screen. I thought maybe the RAM was bad so I inserted 2 other chips (we ordered 4 X 2GB to upgrade 2 iMacs) and still no luck. After making sure the iMac would boot with the old RAM (which it did), I tried installing 1 X 1GB with 1 X 2GB and it booted up perfectly. I did this with all four 2 GB RAM chips to make sure they all worked and they did. Each time I successfully booted, I went to the system profiler to make sure it recognized 3GB of RAM and it did. So my question is why is this mid 2007 Aluminum iMac not working with 4GB of RAM, but it works perfectly with 3GB? Thanks in advance, sorry for the long question.

+It seems to me that it is not just a problem with the RAM but with the imacs themselves.+
How does this make any sense when one considers that Apple successfully specified, produced, sold and delivered all three iMac (mid 2007) models with an optional 4GB of RAM pre-installed?
In addition, Apple has, without issue, sold large quantities of that same RAM online and over-the-counter for customer upgrades. Much of all that 2GB, and the latest 4GB RAM, as usual, has been manufactured by Micron, the publicly owned U.S. manufacturing company parent of the Crucial direct sales division. The same type of RAM was also being provided to Apple by other manufacturers.
I received my two orders of upgrade RAM from Micron/Crucial even before I had purchased my 24-inch iMac, and it's worked great ever since I installed it. I also installed the second half of that order into my current MacBook, purchased a month after the iMac, and it's also been working great ever since. These are certainly superior Apple products.
Obviously there has been a change in RAM manufacturing design at Micron, probably due to their change-over to the costly, challenging high-tech 50nm and 40nm manufacturing technologies, and it is nothing more than Micron's problem.

Hi, I bought an imac 27" quad-core i5 with 1067Mhz DDR3 RAM in it. I would like to know if this is the right type of speed for my imac as I found out that these imacs come standard with 1333Mhz DDR3's? It is crashing a lot!

Hi all. I bought an imac 27", 3.1Ghz quad-core i5 Mid 2011 last year in 2012. The machine has been crashing ever so frequently. I upgraded the RAM from the 4Gb it came with to 12Gb. It still crashes! I recently noticed that my imac came with 1067Mhz DDR3 memory chips ( slower speed) than the Apple mac recommended 1333Mhz DDR3 memory chips.
The shop I bought it from ( Incredible Connection, Woodmead, South Africa) are refusing to own up as they are saying the 1333Mhz chips have to be ordered in advance. Surely they are supposed to sell the product with the right kind of Ram in it? Not for me to find out? Now I have to fork out more money to make my imac factory standard? Maybe I am wrong, But do these Mid 2011's run well on 1067Mhz memory chips if I upgrade to 32Gb? Is it possible people are swapping 1333Mhz chips from new machines with 1067Mhz chips which are way too cheaper? My system version( SMC Number) is 1.72f5
Baffled!

Mac and Mac models are picky about the RAM the Mac needs to see and use.
As you have found out, the 1067 speed RAM will not work in your year and model iMac.
You need the 1333 speed RAM.
If, you can return the RAM for a refund, do it!
If not, try online Mac RAM source and seller Crucial memory. They have a table that matches your Mac to the correct and reliable RAM. You may need to contact them to see whether or not they ship to South Africa, though.
If Crucial dpesn't work out, here's the specs for your year and model iMac that you need to seek out and purchase.
Maximum Memory
32 GB (Actual) 16 GB (Apple)
Memory Slots
4 - 204-pin PC3-10600 (1333 MHz) DDR3 SO-DIMM
Good Luck!

IMac 3.06 GHz Intel Core 2 Duo with 12gb of RAM running very very slow.

My late 2010 iMac 3.06 GHz Intel Core 2 Duo with 12gb of ram is running very slow. It takes a very long for the computer to boot with the desktop taking ages to fully load. Applications are also taking an unholy amount of time to load with the spinning wheel always appearing through out use, and they often crash or don't respond and close during use. I'm talking applications like Word taking 3 minutes to load and getting the spinning wheel when font size is tried to be changed and crashing and closing if a large volume of text is attempted to be pasted into a document.The computer is also failing to shut down properly just staying on a blue screen. I recently wiped and completed a fresh install however the issues came back.
As you can imagine after spending so much on the computer I'm not best pleased about these issue, I've spoken to the apple staff in my local store by they weren't very helpful and seemed to no little about computers and the so called "Genius" who I spoke to about my issue was a joke, repeating himself and talking utter rubbish, while I understand you need to look at a computer to get a real picture of an issue, some advice could of been provided. I haven't got time to take the computer to the store at the moment and get a technician to look a it, so I was wondering if anyone else had experienced these issues and knew what caused the fault, and that way if possible I can repair the issue myself.
Thanks in advance for any help on the issue it’s much appreciated. At the moment I'm pretty close to ditching the thing and buying an Alienware!

IMac G5 (iSight) with 10.4.11: Screen always dimmed. Starts at full bright and a second later dimms and stays like that forever. Brightness controls work normally under this circunstance. Please help !!!

iMac G5 (iSight) with 10.4.11: Screen always dimmed. Starts at full bright and a second later dimms and stays like that forever. Brightness controls work normally under this circunstance. Please help !!!
Please don't tell me to adjust anything on the preferences, since I have tried all. I think it may be anoter kind of problem, maybe hardware related or anything.
I ran the Hardware repair DVD and everything was ok, but when the imac restarted the screen was very lit again, but when it went sleep, when it went awake again the screen got dimmed again. Because of that I think that the problem could be software related, but who knows. Excuse my english.

I can't see another possible answer - the longer your machine is up, the more the power supply is stressed, it protects itself by dimming the screen to lower the draw on it.

My quicktime is very jerky with 1080p video but when I play the video file in FCPX its smooth. I recently upgraded to OS mavericks on iMac with 16gb of ram and should not be having this problem. Is it possible to reinstall older software?

My quicktime is very jerky with 1080p video but when I play the video file in FCPX its smooth. I recently upgraded to OS mavericks on 2011 iMac with 16gb of ram and should not be having this problem. Is it possible to reinstall older software? I cant figure whats causing the jerky video so I'm assuming its the new OS. Any one have any suggestions?

I have the same but not the same problem. When I play a sound or a video on a website (other than youtube)on safari, a weird nois is comeing from the speakers, the sound has pops/clicks but if I play the same video/sound on mozilla it works fine.. If wnyone know what's the problem.. please let us know

External Apple isight with a imac G5

Really need help to figure this one out.
I have not used this isight before it has been bought secondhand.
Trying to use an external Apple isight with a imac G5 (without built in isight) running on Leopard OSX 10.5.8.
looked in my Utilities and can't find anything relating to isight.
Done system update and tried to download isight updater 1.0.3 but that does not work for OSX 10.4 or later.
Many thanks for your time
Additional Details:
Also when I go into System profiler and look in FireWire it says unknown device.
and also went into:
finder/system/library/coreservices/isightupdater
It will ask me to plug in an isight (which I do) to install and still nothing happens.
& also best till last - No green light what so ever
Do you think it maybe broken?
I really hope not as it was sold as fully working

Welcome to Discussions, jonsonby
Based on the info you posted, if Defcom's good suggestion does not restore proper function, I think the external iSight is defective.
The simplest way to test that for certain is to connect your iSight (use the same cable you use) to another Mac, particularly one that works with a known-good external iSight. If you do not have access to another Mac and/or another external iSight for testing, a local Apple retailer may be able to do the test for you at little or no cost.

Do you have any ideas why Motion 5 would run slow on a computer? I have an Imac with 8Gigs of ram, and plenty of hard drive space, but it still gives me the beach ball when I add a few lights and effects. I'm at the end of my rope.

You probably don't really need 1080 at 60 for your finished projects but since you're just starting out with Motion, you need to lower your expectations. A long way. 1080 is about 2 million pixels per frame, DV is only about 400,000. That's not just five times as many pixels for the Mac to track; everything in video is exponential.
Explore the training tutorials available by Mark Spencer. You will get an idea of how his super powerful machine reacts with the software.
Adding a light roughly doubles the processing time over flat scenes. Two lights increases processing again. Reflections require processing the lights and then calculating the reflections so add another quarter of the time required for flat scenes. Add camera movement, motion blur, and depth of field and you need exponentially more processing time for every frame. The preload of renders into RAM is one of the cooler features of Motion, as comapred to After Effects, but that takes tons of time, to.
Try working in ye olde DV resolution for a few days. Get to know the software's limitations and what gets imposed by your Macintosh. Step up to 720p/30 and see how things slow down.
