Hey guys, Looking to upgrade my ram on this, (If possible) http://en.wikipedia.org/wiki/File:Apple_PowerMac_G4_M8493_QuickSilver_front.jpg It's the dual 1Ghz model more info here, under "Four-slot models" http://en.wikipedia.org/wiki/Power_Mac_G4 Right now it is running leopard 10.5.8 and has 3 512mb sd ram installed. It shows as 1.5GB SD ram. I read somewhere that OS9 would only recognize up to 1.5GB of ram but OSX could recognize up to 2 GB. Any truth to this? If so what ram should I install and what sizes in the 3 slots? Thanks!
