Recently i bought 8GB of ram for my MBP my previous configuration for my laptop is 13inch 2.53 ghz and 4gb of ram and 60gb ssd. i never had problems with this configuration. when i upgraded my laptop to 8GB immediately the day when i installed the ram i had a problem with my logic board. I sent it to repair and i got it fixed for 300 dollars since its out of warranty. When i got back my laptop i am noticing kernel panics on my laptop. i sent it to apple back and they told me its a hard drive problem and it costs 700 dollars to fix it. I asked them to ship it back. I received it today and i replaced my SSD with old apple hard drive i still had the problem. on a final thought i replaced my 8gb ram with 4 gb ram. now every thing works fine. the new ram which i have is 8gb 1333 mhz. my old ram is 1067 mhz Do you guys think every thing happened because of the ram. Also on the other note, one guy from apple told me that if i had a problem one more time they might give me a new laptop, now i have a chance to replace my 4gb(apple given) ram with 8gb(new ram) and send it back to them. have any guys had this kind of situation where they got a new laptop back.
