Apples official limits are set by what size DIMMs are available at time of manufacture & never updated again, if your eMac does indded support 2 GB as mine does, then you''l see no degradtion, but vastly increased response & usefulness!
So we know more about it...
At the Apple Icon at top left>About this Mac, report the version of OSX from that window, then click on More Info, then click on Hardware> and report this upto but not including the Serial#...

Like BD, I have a later eMac 1.42gHz that is happily running with 2GB RAM. However not just any old 1GB modules will do. They must be tested in Macs.
This is the link and the vendor I used in going to 2GB. Known good stuff:
It is important to remember that there are two familes of eMacs--those with USB 1.1 ports and those with USB2.0. The USB1.1 eMacs have the model Identifier "PowerMac4,4" in System Profiler. A 4,4 eMac CANNOT use more than 1GB RAM (two 512MB modules). The USB 2.0 eMacs are coded "PowerMac6,4" ar BD posted adn will run perfectly with proper 1GB modules.
just to drop in. I have a mid 2009 macmini. it has stated a max ram of 4gig (2x 2gig chips). what I had loaded into it was 2x 4gig chips (total twice what is stated in specs) runs really great. use it mainly to run FCExpress4 with op sys 10.6.8.
no faults, errors or any other mem troubles. .....interesting eh?
I really appreciate all the help this forum/discussion board has been giving me, I am going to go full-steam ahead with this eMac to get it up and running as a secondary computer (It's to replace a very slow PC) and even though this one may be slow as well, I'm pretty sure it won't crash every 15 minutes.
Tomorrow, I'm going to be checking out the innards of the computer, is there anything odd I should look for in the PSU, or anywhere else that might indicate damage?
(I already know the capacitors telltale signs, swollen, leaking, etc)
