IMac 333Mhz memory and slots

I recently pick up an iMac 333MHz (tray loading)with 64 mb of memory and would eventually like to get it to OSX.
I have located the main memory slot according to the instructions, but understand that their is a second memory slot. I have been unable to locate it or find instructions on how to add additional memory to the second slot. I understand that the 333MHz iMac can have 512mb (2 x 256mb). If anyone has instructions on how to access the second memory slot and also a resource to get memory for the iMac I would appreciate it.

I recently pick up an iMac 333MHz (tray loading)with 64 mb of memory and would eventually like to get it to OSX.
Note... The lower slot requires low profile memory. You can put the low profile memory in the upper slot if you want.
From what I read, most people feel the 333 machine can take 512meg of memory.
Be sure to update the firmware before moving to Mac OS X 10.2 or 10.3.
You should verify that you have the latest firmware, before installing new software. See the system profiler for details. What firmware do you need?

Mac OS X takes about 4gig of harddrive space.
This will require a minimum of 128meg of ram. You may put 512meg of ram in this machine. There are two memory slots. One must be Low Profile memory. Be sure you can return your memory cards. iMac memory cards are finicky.

All the tray loading iMac g3's, models a-d, are constructed the same.
Here is a good disassembly page:
http://www.macopz.com/columns/imacrepair/disassembly.html
The second article in this series has information on replacing the battery:
http://discussions.apple.com/thread.jspa?messageID=2584291
The tray loading iMac requires the boot partition to be within 8gig. Since there are hidden partition before the first visible partition, people recommend that you make the first visible partition 7.5 gig to 7.9gig. The machines support upto a 128gig Parallel ATA drive.
You should be able to use Unix symbolic links to 'move' some directory like /Users to the second visible partition.

How do I add more memory to my Imac, I only have 1GB of memory and need 2GB to download Yosemite!

How do I add more memory to my Imac, I only have 1GB of memory and need 2GB to download Yosemite?

Janet,
This is why the question rkaufmann87 asked about your model is so important:
[click chart to enlarge if needed]
The list covers the early iMacs with Intel processors that shipped with either OS 10.4 or 10.5 and have only two RAM slots. As you can see, some have limits to what version of OSX you can install. If the step rkaufmann requests does not narrow down your model, you can do one more thing.
While the "About this Mac" window is open, click the "More Info..." button at the bottom of that window to get this (assuming you are really running OS 10.5.8 as shown in your profile):
The code I've indicated with the red arrow corresponds to the codes in the second column on the chart. Post the code your computer reports--again don't post a serial number.
If your iMac shipped with only 1GB RAM, I fear it is one of the earliest models that cannot be upgraded all the way to Yosemite.

I have an iMac 5.1 with Mac OSX 10.6.8 and 2 GB memory and an L2 cache of 4 GB. lately I have been receiving error messages of " start up disk almost full; please delete files." is the start up disk the same thing as the hard drive?

I have an iMac 5.1 with Mac OSX 10.6.8 and 2 GB memory and an L2 cache of 4 GB. lately I have been receiving error messages of " start up disk almost full; please delete files." is the start up disk the same thing as the hard drive? I opened the hard drive and from the column on the left of the menu I've selected "search for" and under that " all images" then "all documents" I've deleted a few files from each. Are documents and images that I have deleted from here also deleted from the folders on my desktop?

You should never, EVER let a conputer hard drive get completely full, EVER!
With Macs and OS X, you shouldn't let the hard drive get below 15 GBs or less of free data space.
If it does, it's time for some hard drive housecleaning.
Follow some of my tips for cleaning out, deleting and archiving data from your Mac's internal hard drive.
Have you emptied your iMac's Trash icon in the Dock?
If you use iPhoto, iPhoto has its own trash that needs to be emptied, also.
If you store images in other locations other than iPhoto, then you will have to weed through these to determine what to archive and what to delete.
If you use Apple Mail app, Apple Mail also has its own trash area that needs to be emptied, too!
Delete any old or no longer needed emails and/or archive to disc, flash drives or external hard drive, older emails you want to save.
Delete any other mail in your Junk folders. Also, look through your Sent Mail to see if there is anything that can be deleted.
Other things you can do to gain space.
Once you have around 15 GBs regained, do a search, download and install OmniDisk Sweeper.
This app will help you locate files that you can move/archive and/or delete from your system.
STAY AWAY FROM DELETING ANY FILES FROM OS X SYSTEM FOLDER!
Look through your Documents folder and delete any type of old useless type files like "Read Me" type files.
Again, archive to disc, flash drives, ext. hard drives or delete any old documents you no longer use or immediately need.
Look in your Applications folder, if you have applications you haven't used in a long time, if the app doesn't have a dedicated uninstaller, then you can simply drag it into the OS X Trash icon. IF the application has an uninstaller app, then use it to completely delete the app from your Mac.
Download an app called OnyX for your version of OS X.
When you install and launch it, let it do its initial automatic tests, then go to the cleaning and maintenance tabs and run the maintenance tabs that let OnyX clean out all web browser cache files, web browser histories, system cache files, delete old error log files.
Typically, iTunes and iPhoto libraries are the biggest users of HD space.
move these files/data off of your internal drive to the external hard drive and deleted off of the internal hard drive.
If you have any other large folders of personal data or projects, these should be archived or moved, also, to the optical discs, flash drives or external hard drive and then either archived to disc and/or deleted off your internal hard drive.
Good Luck!

I bought my 20" iMac in Nov of 2007 and when I try to purchase the upgrade for lion I'm told I need 2GB of memory and I only have 1GB. How can I get more? I am currently running snow leopard

Trying to upgrade to Lion on my 20" iMac that I bought in Nov. 2007. Currently I'm running on MAC OS X version 10.6.8. When I tried to buy the upgrade I got a response that Lion requires 2 GB of memory and I only have 1 GB. How can I get more memory and will my computer be compatible with Lion when I do get more memory?

Yes you can install more RAM. Up to 6 GBs. Two - 200-pin PC2-5300 (667MHz) DDR2 SO-DIMMs. For the maximum use one 4 GB and one 2 GB. Otherwise install a pair of 2 GB modules for a total of 4 GBs.
You can purchase suitable RAM at DataMem or OWC. OWC also has video tutorials on installation.

How Can i clean my memory and make my imac more faster ?

I am new user in mac i have imac 4 g ram and need a way to clean the memory and make my imac more faster ...

You can't "clean" RAM. If the "storage" space on your hard drive isn't enough then put in a larger hard drive or delete any of your data you no longer need or can store on an external drive. Beyond this I cannot say because you have not provided enough information such as the amount of installed RAM, Capacity of your hard drive and the amount of available space on the hard drive, the specific iMac model you have.
You can try reinstalling Lion:
Reinstalling Lion Without the Installer
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alterhatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion and click on the Continue button.
Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.
However, if your computer doesn't have enough RAM or your hard drive is full, then reinstalling won't help.

I have an iMac with only 1Gb of memory and am running OS X 10.5.8; do I need to upgrade it and if so, to what?

I have an iMac with only 1Gb of memory and am running OS X 10.5.8; do I need to upgrade and if so, to what?

Michel PM and CRP 101, thanks for your replies.
My machine was purchased in 2007, I think. It's model iMac8.1 with the Intel Core 2 Duo processor and CPU speed is 1.07 GHz.
What I am asking has to do more with the OS X opsys version than the size of the memory. My question is prompted by my son suggesting that I should upgrade and purchase MS Office and substitute for the factory-provided OpenOffice.org application.
Thanks!

When I connect my iPod3 to my Imac, the memory shows 13GB or so assigned to "other" (color coded yellow). What is this "other, and can I clear it?

When I connect my iPod3 to my Imac, the memory shows 13GB or so assigned to "other" (color coded yellow). What is this "other", and can I clear it?

The "Other" section on your iPod consists of several different things including album artwork, files you may or could be storing on it externally when using the iPod as a storage disk, the iPod's software/OS, as well as corrupt files that are leftover from failed sync operations with iTunes or are no longer recognized by the iPod's software or iTunes. The size of other is usually quite minute, around less than a GB, sometimes a little more (depending on the amount of media stored on your iPod).
In order to clear this space out, you'll need to restore your iPod to factory settings in iTunes.

USB ports and memory card slots not working

My Pavilion a6120n desktop has worked brilliantly ever since I purchased it. As of last week the 2 usb ports in the front and the 2 unused usb ports in the back have stopped working. My printer is plugged into one rear port and my wireless mouse is plugged into a second rear port and these work fine. I generally use a memory stick for data swapping or the card reader slots (which have also stopped working). I no longer see the memory card icons in the "Computer" window. When installing something new the "New Hardware Found" statement pops up but the driver install always fails. I think it is a software issue but there are no usb drivers to download on the HP/support site that I can find. . . so . . . Below is what I have tried so far.Run antivirus software. Full scan & memory scan - no issuesRun malewarebytes full scan - no issues I have tried restarting several times with no success. Restore to several previous restore points = failedRestarting computer in repair mode = failedRun the repair disk that I had made = failedChecked the power management for each usb port to see if the power was routed properly = okRemoved the case cover and carefully inspected the wiring and connectors.finally I tried uninstalling the usb drivers = failed Upon restarting the computer the last time the startup file must have failed and after several hours of attempting a repair I had to reinstall the Window 7 completely. Still no usb or memory card function. Any help would be appreciated Thanks,MrBob38

Imac 333mhz/96mb battery location and replacement

My fruit colored imac 333mhz/96mb is not turning on. I suspect that the original battery has died. Where is the battery location and replacement information?

Thanks! I also just found this: http://www.djonmac.com/battery/changebattery.html

Don't know. Could be any number of reasons. Re-read the how to install RAM manual again for your model iMac. Double & triple check to make sure you purchased the right RAM chips. Make sure they are seated properly. If you didn't hear a snap when seated, the RAM is not properly seated.

Just upgraded an iMac with 4GB Memory and Intel Processor from 10.6.8 to Mavericks and Quicktime plays m4v files with stuttering audio

I just upgraded an iMac with 4GB Memory and 3.33 Ghz Intel Core Duo Processor from 10.6.8 to Mavericks. I now have Quicktime 10.3 which plays m4v files with stuttering audio. This is a nightmare as I use Quicktime a lot in my research. I have seen similar threads but so far only reporting the problem. For now I have installed Quicktime Player 10.7 (which appears in utilities, leaving Quicktime 10.3 in the main applications list) which plays the same videos with no problem, but it would be good to know if anyone has managed to find a workaround at all, or know if Apple have plans to do anything about it?

Slow performance after installing Yosemite on an older Mac is often caused by inadequate memory. Although you can install the upgrade on a Mac with 2 GB of memory, experience has shown that at least 4 GB is needed for full performance.
Select About This Mac from the Apple menu. If you have less than 4 GB of memory, and your model has upgradable memory, install as much as it can take, or at least that much. Any reputable RAM vendor will have a web form in which you can select the Mac model and be directed to compatible parts.

Maximum total memory and per slot, N500

I have a 4233 4DG with PM45 chipset. It has two memory slots. I'm currently using 2X2GB of RAM but would like to use two bigger sticks of memory to increase the total capacity? Does anybody know what the total maximum memory amount is or is it limited by maximum memory per slot?
Solved!
Go to Solution.

maximum memory is 4 gb with windows 64-bit ( 2x2gb ) for n500.

27 inch iMac for editing and After Effects

Hey everyone. I'm a student who does heavy video and After Effects work. Right now my core 2 duo macbook pro is not cutting it when it comes to performance and render times.
Luckily, my budget is around $2200-2300 thanks to money I should have leftover from my college fund (thank you, mom and dad).
I was looking at the MacBook Pro 15 inch until I discovered the 27 inch imacs that are in the library multimedia center. The screen size is great because there's so much space to work with and details come out a lot clearer.
But from a hardware and price perspective, the 27inch imac with a quad core 3.1 ghz intel core i7, 1 tb hdd, and a 2gb AMD Radeon HD 6970m is around $100 LESS than the MacBook Pro with a quad core 2.4 ghz, 750 gb 5400 rpm, and 1 gb 6770m.
The only tradeoff is portability, but given the difference in spec, i'm starting to say its worth it.
I know that a lot of AE is dependant on CPU and lots of RAM per CPU. Upgrading to 16 gb of ram is getting cheaper and cheaper (it also helps that the imac has 4 ram slots). The iMac can actually support 32 gb of ram, so when that becomes available that is another nice plus.
So just doing the math, with 16 gb of ram that would be a 3.1 ghz quad core intel i7 with 4 gb of ram per core. 8gb of ram when upgraded to 32 gb of memory.
I'm not sure what Apple is gonna do with the next iMac refresh, so I will probably wait until then to make a decision.
Does anyone have experience with AE on the 27 inch iMac with similar specs?
Many thanks,
Dan.

Several other drawbacks to the iMac or any other all-in-one computer system:
1) The GPU cannot be upgraded at all (at least not internally). In fact, iMacs cannot have their AMD (formerly ATi) GPUs disabled at all. And Premiere Pro CS5.x supports only NVIDIA CUDA GPUs for MPE GPU acceleration. (The current iMacs cannot be equipped at all with any GPU besides AMD/ATi.) Premiere Pro is thus forced to run in MPE software-only mode, which is much slower than with GPU acceleration.
2) No iMac has any room at all whatsoever for more than one single fast internal hard drive. Unfortunately, the interface that the iMac employs, SATA, is only a half-duplex interface (which means that data transfers can only move in one direction at a time). But video editing requires a disk system that does simultaneous reads and writes - but with only one disk connected only by a half-duplex connection, the system must wait for a given block of read operations to be completed before any writes of a given data can even begin at all. This slows down overall editing and encoding performance substantially.
3) Additional hard drives can be added externally - but the current external hard drive options available for the iMac are either very expensive or very slow. That's because the iMac has absolutely no USB 3.0 or eSATA capability whatsoever. The iMac has only USB 2.0 and Thunderbolt ports - but external Thunderbolt hard drives still cost nearly twice as much money per GB as other external hard drives, and USB 2.0 is limited in sequential transfers to only around 35 MB/s - far slower than the drives themselves are physically capable of (140 to 188 MB/s). Plus, of course, USB 2.0, like SATA, is only half duplex.

Late 2009 iMac (Intel) memory upgrade.

My late 2009 iMac (Intel) has 2 2GB memory chips (4 GB total). Can I add 2 4GB chips to the two empty memory slots (12 GB total),or do I have to pull the 2 GB chips and use 4 GB chips in all 4 slots (16 GB total)?

Yes. Depending on the model it will use 8 GB (early 2009 20" & 24" iMac and mid 2009 20" iMac) to 32 GB (all late 2009 iMacs) of memory. So just replace the 2 GB modules modules from either Crucial.com or otherworldcomputing.com. They are the two most reputable suppliers of Mac memory out there.
