[LeoTheLion89]

i am resurrecting my old iMac Tray Load 333MHz G3 i have read that 512MB is the max you can unofficially install into this machine however i also read this only works SOME of the time i have 256MB in it using RAM from a old laptop is that enough? also sitting unusable since late 2009 i have lost and found meny parts except the plastic case cover over the logic board, looking online i can buy the entire case however all i need is the logic board cover which i cannot find seperatly any idea where i can find one?

Oh, for Pete's sake. You don't have to "also read" anything. Download the free MacTracker application. It includes complete rundown on every Mac model ever made along just about every software title and peripheral Apple ever sold. The MacTracker application is immeasurably faster than the MacOSX.com fan forum.

for awhile now i was planning on converting all my desktops to Solid State drives by using a IDE to CF adaptor well i decided to do this on both my iMac G3 and my eMac Rev. C with the 8GB limit for OS install my iMac is simple a 8GB CF card and a 16GB card is enough for the eMac with Leo what i am asking is has anyone installed OS X on a SSD? hows it preform? just trying to see if this SSD conversion will improve OS X preformance.

Any excuse .... The CPU information--the information that you need--in MacTracker comes from the apple-history.com website.

looking online to find out how well Tiger preforms on a original iMac i came across this

I've learned a lot from Bill. For instance, some tray-loading iMacs think they have 32 MB memory modules installed when running Mac OS 9, but when booted into any version of OS X, the recognize them for what they are: 64 MB modules. So any time he sees a Rev. A-D iMac reporting 32 MB modules, he boots into OS X to see if they're real 32 MB cards or misreported 64 MB ones.

He's also the only person I've ever heard from who has managed to get 512 MB RAM cards working in tray-loading iMacs. He writes, "We have found two of these early iMacs, likely 333s, that would accept and report a 512 MB card. We don't hold our breath looking for these rarities. We have no idea if these two iMacs will accept two 512s." Bill isn't 100% certain, but he's pretty sure that the successful 512 MB modules were "CL2" memory; when he tried with "CL3" RAM, it didn't work. He says, "Being marked as PC-100 vs PC-133, or 222, 322, or 333 was no issue. CL2 or CL3 was."

Bill also reports almost universal success with 256 MB modules in tray-loading iMacs. I've been one-for-two with a pair of 333 MHz iMacs, and many others have less luck than Bill. He says it may be due to memory issues, such as the 256 MB CL3 module that every iMac sees as having only 128 MB. But if the memory is marked CL2, it will work. If you've installed the latest firmware update, you may have as much luck as he does. If not, you should be able to get 256 MB working in the larger RAM slot, 128 MB in the smaller one for a total of 384 MB. Bill reports 100% success with 256 MB CL2 memory.

so does this mean i can unreportably install 1GB RAM?

That article does not try to represent that 2x512MB chips will work.
The only impression is that ONE might work, in some 333MHz iMacs - so you would have a max of 512MB, which is what that model will recognize.
The article says "...the only person I've ever heard from who has managed to get 512 MB RAM cards working in tray-loading iMacs..."
What I get from that short article is: SOME 333 MHz iMac will recognize SOME 512 MB chips as 512MB of memory.
Mr "Bill" in this article "reports 100% success with 256 MB CL2 memory.", so I assume that 512MB is a much lower success rate (that might be an invalid assumption, but it's just a conclusion that I think can be backed up with actual experience.)


I don't think you can imply from that article that you can successfully use 2 x 512MB chips but possible one could work (if you can find one that works)
It's also probably a function of the processor card in use - there's several different revisions that came with the iMac when new, and that article doesn't seem to mention that at all....
