I have an iBook / PowerBook4,3 model A1005 (600MHz PPC) that I am trying to upgrade the RAM on. According to everymac.com it can take a single 512MB PC100 SODIMM. So I bought one and when I plugged it in, the iBook only reconized 256MB of additional RAM. So I thought that the stick might be mislabeled or bad, and I returned it.
I bought another stick from another vendor (Memory Masters) that specifically stated it supported my model of iBook. I just plugged it in and the iBook still only recognizes 256MB of additional RAM (total of 384MB).
System Profiler reports the SODIMM as 256MB, and it reports the iBook has a boot ROM version of 4.3.6f3.
Do I need a firmware update? Or is everymac.com just wrong about the RAM support?
