Q: Ram upgrades for an eMac 1.25

I just purchased 2GB (pair of 1GB) PC3200 184 pin memory chips that I plan to use to upgrade an eMac 1.25 some time in March when I visit my son. However, I tested them today on a PowerMac G5 1.8 and they read as 2, 512 MG chips. Will the eMac also read them as 512s? Do I need to get PC2700 chip or do I need to get them from OWC since they offer them as upgrades for this machine. The ram chips were made by Kingston.

MacBook Pro, OS X Mavericks (10.9.1)

The eMac requires:

 

Maximum Memory2.0 GB (Actual) 1.0 GB (Apple)
Memory Slots2 - PC-2700 DDR333 184-pin SDRAM

 

You cannot install something different in a computer that uses different modules.

    Kappy thanks for you response and direct answer, but I do have a follow up question before I mark this as solved. Since System Profile on the G5 is reading all four as 512MB PC-3200 and they should be installed in pairs. Colud this mean that one of the resently added 1GB PC3200 chips is faulty? Again thanks.

    What you see--modules reporting as 1/2 their rated size--is common with hi-density RAM intended for PCs. Macs of that vintage require standard density RAM.

     

    I have an eMac 1.42ghz successfully running a full 2GB of RAM, but I bought the RAM from one of the few vendors I trust to get the proper Mac product to me. This is the RAM I bought:

    Before buying the above. I had looked at RAM at some brick/mortar office and electronic superstores but quickly found their PC RAM modules were hi-density and not usable in a Mac. The OWC RAM has worked flawlessly.
