Where did my VRAM go???

I bought a new Powerbook in May and upgraded to 128 of video ram, as well as boosting the memory.

I double checked these in the system profiler when I got the machine.

However, I am having trouble installing the new 10.4.3 update and happed to look in the Apple Profile again .... only now .... it only shows 64MB VRAM!

Where did the other 64MB go????

Is this actually two chips and maybe one has gone bad already???

Thanks for any light anyone can shed on this!

David,

I wouldn't panic just yet. You'll find the following topic below to be of interest. While there is not enough information known yet it seems, anecdotally at least, that the System Profiler is not reporting accurate information about system. As you can see from the other topic I did not have any errors listed regarding the Sudden Motion Sensor (although others did) yet it did not report as being active in the System Profiler. Through Console however I was able to determine it was in fact 'turned on'. Try using restart and see if the missing 64MB VRAM shows up again.

I've tried retsarting - no luck.

I've now gone so far as to wipe my drive and reinstall the system software.

Although I was then able to get the 10.4.3 update to finally work, System profiler is still telling me I only have 64 mb of video ram.

I've read elsewhere that ram slots can go bad. Those post were referring only to memory ram, not video, but I'm now wondering if the same thing could happen with the video ram slot(s).

btw- does anyone know if the 1.67 Powerbooks use two video ram slots or just one?
