I put a 1 gig chip in it (a 200 pin kingsmax chip i found on new egg for $130). the system seems to freeze every once and a while (more often than before when i had 768). I at first had the 1 gig chip in the back and the 512 in the front slot, but it kept freezing so then i switched the ram from the big chip being in the back to the front, and the 512 moved to the back. it seems to freeze less but it on occation does freeze. any ideas?
and yes the ram brands are two differnt brands, but before that didn't seem to matter (the 256 chip was from apple and the 512 was from OWC)
thanks for taking the time to answear my question.
here's the link to the ram
