heycatfish is on a distinguished road

heycatfish is offline
So i'm new here and i tried searching for my problem but i can't seem to find it.
i apologize if i missed a huge thread about it.

I bought a new macbook and gave my powerbook g4 to my mother.
It had the 512mb ram original ram and i upgraded to 1gig of crucial ram.

Since then the laptop will work for a while then either it will freeze, or an error that just says restart your computer will come up.

when working on it the other day upon startup i got this error.

System failure: cpu=0 code 00000008 (unaligned stack)

It works sometimes then fails after its been on after a while.

If i put the old ram it works fine.

here is the ram i installed

i have read a lot about lower socket failure but it still reads as having 1 gig of ram so it reading both slots..

Powerbook G4 1.25ghz
originally 512rm
running Tiger

any ideas?

Thanks from my mother
and for the sake of phone bill cause she keeps calling me with questions!

thanks mac forums!
