Verify the ram module under System Profiler to see if it is indeed 64 MB.
If it turns out to be 32 MB it is either re-labeled or half the memory bank
is not working. The Dutch Chipmunk website could decipher the numbers on
each ram chip to give an idea of its type and capacity.

If you put Kanga ram in a 3400 or put 3400 ram in a Kanga this is what
happens, IF the ram cards are larger than 32 MB. I am not certain if
this is tgrue of ALL brands of 3400 and Kanga ram but it is true of
many if not most. In otherwords, Kanga and 3400 ram is interchangagle
if it is 32 MB or smaller but usually not if it is 64 MB or larger.

I just got a 64 Meg module for my 3400 from ebay. There is a 64meg label on
it, looks like an Apple part #. My 3400 only sees a total of 48
megs...16+32.
Zapping the pram did not help. Anybody ever seen this?
