After a good five year run, the ram in my MP finally gave up this weekend. Why does this stuff always happen when there's a deadline? What options do I have in finding good 800mhz DDR2 sticks for this machine? Seems to have been entirely replaced with DR3, and thus is becoming very hard to come by. Do I have to stay Mac specific or can I use sticks designated for a PC application? Any good known alternatives out there? Thanks!
