I had posted a thread about putting non "apple" ram in my 1.5ghz, 15", 80gb, superdrive, airport powerbook and got an answer. Now my question is can i use ddr2 so-dimm 200 pin pc2 5400 or anything like that??? i realize it will be more than the laptop can actually use, but its still considerably cheaper than the pc2700 thats on there. Please advise if i can save some money and get the ddr2 ram and still have it help out the powerbook. Thanks guys really appreciate the help
