Found some local RAM (2x4gb) that was apparently pulled out of a MBP. It's Samsung SODIMM 8GB (2 x 4GB) 204-PIN PC3-12800 DDR3, but the RAM I have in there now is 4GB 204-PIN PC3-1033 DDR3. Will this work? I tried doing some searching and finding what would work, but didn't come across whether the increased speed. It's a decent price so I wanted to make sure before buying.
