Thank you for the advice Jerry, I didn't know that changing the RAM would require anything like that, I've built Linux/PC from scratch, but have almost zero mac hardware exp. Well, here's my issue now. I got my 2 256M sticks of ram from Coast to Coast memory, they were listed for the iMacs that were 350-700Mhz. Mine is a 350Mhz so I thought I was all set. I dropped the new RAM in, booted up, but it only gets ~1/2 though starting X. It stops on "Starting Directory Services"; it just hangs there. I zapped the PRAM, same issue. So I tried just one stick of the new, same issue. Another stick of the new, same issue. Then the original sticks, same issue! Then just one of the original sticks (64M) and it got into X fine. So I'm thinking if I switch the Original ones around perhaps it'll boot up, but I really need more RAM, that's why I bought it. For my next attempt I'm thinking of reseting the CUDA switch, however as much as I searched online, I can't find any specs on where it is on an iMac. >From the memory door that I've opened I can't see much in the way of the proc or any switch/button. Can anyone tell me how to get to the CUDA switch on a slot 350Mhz iMac? Also, when I recieved the iMac it had 10.1.5 on it, running fine, but this is an eBay purchased box, so it didn't't come with any cds. This is fine b/c I want to upgrade to 10.2, just wanted to get the RAM in first. Should I just get 10.2 and install as normal with the new 512M RAM in there? Will that work, or is the memory 'bad'? I seached Macintouch and didn't find anything helpful, then I saw something on Google relating to the boot stopping at that point, but it was in refernce to an aborted update of 10.1, which is not what I did. But the workaround was to do a fresh install, which I'm not adverse to as I have no files on the iMac that I need. So, what should I do, CUDA it? Contact the RAM folks? (although it seems strange that both are bad, unless this RAM will only with with pre-OS X software (that'd be very odd)) Or just get 10.2 and *know* that the new RAM will 'just work'? Thanks for the help. P<< ------------------------- Well, sorry to hear that resetting PRAM may somehow have damaged previously working RAM. I honestly would suspect that the damage, or issue, was caused while moving the RAM modules around. I also suspect that the iMac may be one of those Mac's that do not have a CUDA. As far as the new RAM modules, I would return them for replacement, or refund. If you read those www.macintouch.com reader reports on Bad RAM, you will find that most having these symptoms had to get replacement RAM; a few had success in doing a PRAM reset (or a CUDA reset if possible on the particular Mac). One, posiibly a couple, readers who happened to be Mac techs have indicated that it is their belief, personal opinion, that the Bad RAM is actually being created at the homefront. In effect, owners are getting good RAM, but through poor handling of the modules, are causing stray electrical discharge damage that can be immediately detrimental, or that can increase through age/use. I couldn't say if it is baad RAM from the factory, or good RAM gone bad at home. It could be some of both. The bottom line though is that you should get replacements for the two new modules, and now maybe for the former old, good one. Jerry -- The iMac List is sponsored by <http://lowendmac.com/> and...
