The tray load iMacs aren't spec'd to work with 256 MB chips. That said, some people have gotten it to work, some haven't. I had good luck with it, and had found that as long as you get the correct density ram, and you watch that the ram retaining clips don't contact any of the chips on the card, then it seemed to work for me. I did several this way. All mine were Rev A or Rev B machines. I recently did it with a 333 tray loader like yours, and I had the same results. No boot at all while a 256 MB was in the top slot, and in the bottom slot it would only see 128 MB of it. I have the correct density chips (they were actually pulled from a Rev A using them to get to 512 MB), and I checked to be sure the retaining clips weren't shorting anything... still no go. So it looks like my luck in the past was just that... luck... and it ran out. Maybe the 333 Apple changed something that stopped it from working with 256 chips. -chris <http://www.mythtech.net> -- The iMac List is sponsored by <http://lowendmac.com/> and...
