I have had my powerbook for about 9 months, 7 of which i have had 1.2gb of ram installed (installed 1gb). But as of the last week, it will only recognize whats installed in the upper memory slot, for example with the 256 chip in the lower and the 1gb in the upper it will only recognize the 1gb chip, or if the 1gb is in the lower then it will only recognize the 256 chip, What is really strange though is if you take the top chip out and leave it out it will recognize the one chip in the lower slot. Any help would greatly help, Oh the 1gb chip is from newegg and worked fine with the the 256 chip fine till last week hope this somewhat makes sense.
Thanks
