Oh it's the 17" 1.25GHz model. It doesn't specify whether the non-user accessible slot is a 184 pin DIMM or a 244 pin SO-DIMM.

This is a terrible blasphemy. Please have some respect and edit the title.

Hello deathkoba,

I believe this Apple Kbase Article will help. :)

EDIT:
RAM: 128/256 MB, expandable to 1,024 MB using one user accessible PC100 SODIMM (3.3 V, 64-bit, 168-pin, 100 MHz, up to 512 MB) and one 144-pin SODIMM inside the computer (also up to 512 MB)

Those are incorrect memory specs for the iMac 17 inch 1.25GHz. The 1.25GHz iMac does not use PC100. It uses PC2700 DDR. Here are the specs from the Kbase.

iMac (USB 2.0) computers only work with PC2700, 2.5V, 333Mhz DDR SDRAM. The maximum installed RAM that can be used is 1 GB. RAM modules of 128 MB, 256 MB, and 512 MB sizes can be used in both slots.

There are two RAM slots in the iMac (USB 2.0) computers. They are:
A user-accessible 200-pin SO-DIMM slot.
An internal (factory-installed) 184-pin DIMM slot

The Apple System Profiler will show the two different types of slots and what amount of RAM is installed there. The user-accessible slot requires PC2700 333Mhz speed DDR SDRAM SO-DIMMs. When installing larger 265MB or 512MB DIMMs in this slot, use low-profile SO-DIMMs.


Hope this helps. :)

It is called for. I am extremely frustrated. I basically bought 2 sticks of SO-DIMM thinking that I can install them in both slots but it turns out that the slot beneath the unit uses a standard desktop DIMM. Should've known better.

And you should know better than a title like this.

We have a winner. I can confirm that those are indeed the right specs for the iMac in question.:)
