ram upgrade iMac G4 1.25/20" - 2009/07/08 11:59 I had an apple authorized shop upgrade my iMac G4 1.25 20" to 2GB.

In checking the ram in the About this Mac hardware the memory component indicates:

DIMM0/J22 1GB DDR SDRAM PC2700U-30330 OK
DIMM1/J20 empty empty empty Empty

Is that how it is reported when there is 2MB of ram? I looks like there was only 1MB added rather than the 2.

What does 'About this Mac' say on the opening window? It should report how much memory is installed. If it also reports 1GB contact the dealer and advise them of your problem. Could be a simple oversight.

You know how it is when you are busy and the darn phone rings and you try to take up where you left off?

Re:ram upgrade iMac G4 1.25/20" - 2009/07/08 20:00 Harry b,

on the opening window it also says 1GB.

the installer said he installed two 1GB but it would not show more than 1GB even though it's there.

sounds like I'll have to lug the "sunflower" back 65 miles to the shop. maybe he didn't seat the ram properly?

thanks,
karen

Re:ram upgrade iMac G4 1.25/20" - 2009/07/08 22:47 Before you drive off anywhere, that machine may read 1GB as the maximum RAM regardless what is put in it.

Have a look at this link from Apple Support. If it is your model, then 1GB is it:-

http://support.apple.com/kb/SP94

For instances I had a FW800 that held 4x512MB modules. A 1GB module read as 512MB as that was all the machine could handle.

Site Sponsor OWC state the machine may handle 2GB in this link, however maybe Apple System profiler only recognises 1GB?:-

You may have to take it up with your dealer by phone first.

Re:ram upgrade iMac G4 1.25/20" - 2009/07/09 12:48 The System Profiler and About this Mac should both read the correct amount installed. When the iMac was first made there were only 512MB sticks available so Apple's specs will always list a lower amount after time and as RAM technology increases. Now 1GB sticks are available and your iMac should show 2GB in both the ASP and About this Mac.

So, either the shop didn't put two 1GB sticks in or one stick is not seated properly. Most likely one is not seated.

You could open the access panel on the bottom to check one stick but the other stick is buried deep inside the Mac. I would look at the easy to see stick and maybe it can be re-seated before driving all the way to the dealer.

There are guides online to help and EveryMac has a link in the specs for your iMac.
