Hi Everybody
I am new to the forum, but have a strange problem after upgrading the memory in my Powerbook G4 1.67Mhz laptop.
Last week I bought 2 x 1Gb PC5300 DDR667 memory sticks from Crucial. When they arrived I replaced the existing 2 x 512Mb PC4200 sticks and fitted the new PC5300 sticks.
Restarted the laptop, and looked at the System Profiler, laptop recognized I now had 2Gb of RAM fitted. I then went into "More Details" and was horrified to notice that the new memory was showing up as PC3200-288....!!!!!
Phoned Crucial, who suggested trying just 1 stick of the new memory, which again read as PC3200-288. I then fitted 1 of each, 1x1Gb and 1x512Mb and the same again 1Gb read as PC3200-288, but the old 512Mb read as PC4200.
I wrote to Crucial showing a screenshot of the problem, and they say it must be a System Profiler error, and that the memory will be running at the PC4200 speeds.
I am not sure whether I would be better off fitting the 1Gb (2 x 512Mb) of PC4200 running at what I think was 444, or leaving the 2Gb of PC5300, which read as PC3200-288 (which would be faster for day to day, low intensity working?)
Has anybody else encountered this problem at all? I went for what Crucial said was a compatible upgrade (they suggested either PC4200 or PC5300 would be OK on their webpage), but was thinking of future-proofing myself for if I decide to go for a MacBook Pro later this year, as the memory fitted to them is the PC5300.
Any help or suggestions would be much appreciated.
