Chosen Solution
I want to upgrade my memory into 2.5G,but problem seems they are not compatible. while added the additional 2G memory the Mac shattered down very ofthen .Besides the memory mode I bought is the required one,thus I accept the solution to remove the original 512M ,unfortinately it’s soldered with the mother board.How to do it then?any tools necessary?
make sure the RAM you are using meets the specs listed in this Apple Knowledge Base article: http://support.apple.com/kb/HT2266 PowerPC G5 processors are very finicky about RAM, make sure you are using quality RAM with a lifetime warranty - don’t buy the cheapest module out there. Sounds like your machine just doesn’t like the 2GB module… hopefully you can return it? If so try a different brand: OWC, Crucial, EDGE, Kingston all offer RAM which works well with G5 processors. You cannot remove the internal 512MB module - it is surface mount soldered onto the logic board.
Thanks David, I ordered the exact same standard as it required.Here’s what the seller described, http://cgi.ebay.com/NEW-2GB-Apple-iMac-G… It’s a Kingston for iMac533 model. Will it depend on the operation system?Mine’s still in Tiger
