I recently purchased 8GB ram for my 2010 13" MBP 2.4ghz, All my web browsers (safari, chrome, firefox) were all crashing 20+ times a day. I also was having kernel panics and having to restart couple times a day. After alot of reading around im pretty sure it was the 8gb ram from OWC must be defective. So i call OWC and they say to remove the ram clean the contacts with a pencil eraser and re install. I did this today and so far so good but i will update later this week.
