How do you replace second RAM card?

I am looking to upgarde my ram and have learned that the 2nd ram card in my computer is not user friendly. How do I replace it?

Couple of tips. First, I find I get less frustrated working on a G4 iMac by holding it between my knees upside down.

Second, getting the bottom back on is a bear, because of the multitude of cables, some of which are barely long enough and require dexterity and vast quantities of patience while reseating the bottom.

Third, there is a spot where you need to scrape off the old thermal paste (use something non-scratching, like a spudger) and replace it with fresh. So do some googling to find more thorough instructions.

I agree - I've done this upgrade before on my 1.25GHz iMac G4 - it's not that hard to do, although you DO need to be careful of the cables joining top/bottom of the case.

some additional photos more clearly showing the cables can be seen here

Main thing to note is that the factory installed so-called "non user-upgradeable" memory is a full-size 184pin SDRAM DIMM, whereas the user-replaceable one inside the bottom hatch is a 200pin SO-DIMM

Good tip on the difference in RAM chips.

ifixit doesn't sell RAM for G4 iMacs. I'm fond of Other World's RAM configurator (macsales.com) but it doesn't offer RAM for the lower slot. Call a salesman there to get the right stuff.
