    Long story short I finally got it working and may have even had it working all along.

    I have used HWInfo32 for a lot of stuff in the recent past and was using it to measure the speed of my ram because it was quick to start up and one-click to get my speed to make sure I had set it correctly in the BIOS. I've got an ASUS Crosshair IV and was setting my G-Skill DDR3 1600 to 1600mhz and in the post-screen it was showing 1600 but when I got into windows and opened up HWInfo32 to check my speed it was saying 666.7mhz (per channel) which means 1333. No matter what I did it wasn't changing.

    I first assumed it might be all the "turbo" software or the power-saving software that came with the motherboard. I uninstalled all of that and still had 666.7 showing. A friend of mine asked me what software I was using to check it and when I said HWInfo he said try CPU-Z which I also had installed. When I checked it, it showed 802mhz... so it was incorrect in HWInfo apparently.

    If anyone else ever has this issue - make sure you use something like CPU-Z instead of HWInfo to ensure that all your stuff is running correctly. It really had me aggravated for at least an hour trying to figure it out.
