About 2 days ago I decided it was time to upgrade my mid-2010 13 inch MBP (MC374LL/A) to 8gb of RAM. It was running just fine for a couple of hours but then kernel_task started flipping out, using over 100% CPU. After some googling I took out the new RAM and put the old RAM back in, with no success. About 5-10 minutes after booting kernel_task goes crazy. This is the RAM I bought: http://www.ec.kingston.com/ecom/con...t=us&LinkBack=&ktcpartno=KTA-MB1066K2/8G&id=3 I really want to get this fixed, college is starting in a couple of weeks and I really need this laptop.\ EDIT:Tried switching RAM around in the 2 slots. Now using only one slot with one 4gb module, up and running for 30 minutes now.
