I have the model mbp just before the santa rose chipset came out so i maximized my ram load at 3 gb and need more? would it be to expensive to replace the chipset? also is their any alternative besides buying a new laptop all together ?
There is nothing more you can do at this point with that machine. I had that same model before I upgraded to what I have today. It's unfortunate, but your computer is 5 years old or there abouts
