Hey Nate you know your ram is running at 800 Mhz not 1066? You have to go in to your BIOS with that G.Skill ram and adjust it to run at rated speed.. I had the same problem with my ram when I got it... I have the same ram also. You have to bump up the voltage to around 2.0 volts and change the frequency to 533 Mhz. This may also change the timings but you can change them back as well....
**Edit** Also make sure to run memtest to make sure that it is stable because I heard some people were having trouble running at rated speeds.
