I recently replaced the RAM on my aluminum iMac from 1gb to 4gb.
Can I put the 1gb RAM in my older white iMac which has only 512mb RAM?
These are the exact 2 iMac's I have.(not my pic)

You didn't mention the exact specs. of your two iMacs so I could look up what memory each one uses...but generally speaking, memory (ram) is not backwards compatible.

From the looks of your 2 iMacs...the older one uses PC-5300 ram & the newer iMac uses PC-8500. This is just a guess, since I don't know the exact models you have.

Ahh...that info helps out quite a bit! Your 2 iMacs are a lot closer in age than I assumed.

They both use PC-5300 667mhz ram...so my guess is that the ram you removed from the newer iMac should work in the older iMac.

Would using faster memory be of any value in my older IMac. Older imac is 20 in 2.1 gig and has 2 gig ram[not sure of speed] but removed 2 gig 800 meg ram from new Imac[installed 4gig] 2.8gig. Is this just a waste of time or would there be some value to this.
