all the ones with this problem are 1GHz
wouldn't the ram be good because the computer can boot off of it?
I do have a stick of crucial brand ram which i know is good because it came out of a powermac g4 that always and still works.
I've used Windows computer ram in some of my Mac's (iMac G3's & eMac)...and sometimes they boot & sometimes they don't. In other words if I install ram I know came from a Windows computer (PC100 or PC133)...and I install it into one of my iMac G3's or eMac...sometimes they will boot fine...then if I remove the Windows ram...then reinstall it a 2nd time (the exact same stick of Windows ram)...sometimes the computers won't boot.
If I use ram guaranteed to work in a Macintosh...then it works every time.
Regarding the Crucial ram. It's not just that it's Crucial ram...it still needs to be guaranteed to work in a Mac. Mac's (especially) older Mac's can be very picky about the ram they use.
What I'm really saying is...if you had some ram that you knew 100% worked in a Mac (like this ram that came from a Powermac G4 & works fine in that Mac)...then you would know 100% that if you installed this ram into the eMac's you have (assuming the ram from the Powermac G4 is the same used by the eMac's...which I think that it is...PC100 or PC133)...then you would know that the problems with the eMac's is not ram related.
The 4 beeps you're getting with the e-Mac's (according to the definition) means
"4 beeps = no good boot images in the boot ROM"...which would mean that something is wrong with the motherboard/logic board. One, two, or three beeps are related to ram problems...4 beeps means bad logic board, 5 beeps means bad CPU. So we're basically "beating a dead horse" here fooling around with the ram...when it's probably a logic board issue...which is not really worth repairing.
If all 4 eMac's are doing the same thing (4 beeps)...they all probably have logic board problems...and that's probably why you got them for a very good price. They're probably good for parts only...sorry.
This is the best observation/guess I can make with the info so far.
