What do you mean by "I've used the check list"? The Kingston HyperX RAM usually requires ridiculous amounts of voltage. That's the first place I'd start. Did you perform all the steps in the checklist, including trying each stick of RAM by itself? Did you build the system with the motherboard outside the case on a non-conductive surface to rule out a short?
That's a pretty old motherboard model. I wouldn't be surprised if it needs a BIOS flash to support your new CPU. In fact, it looks like your CPU isn't supported by your motherboard until a BIOS revision that was just released a week and a half ago:
You have to click on the CPU model in the list, then it takes you to a list of motherboards that support that CPU and which BIOS version is required. It looks like his motherboard needs BIOS version 846F1P07 released on 08/07/09. At least that's how I took it. It sure is a horrible site.
Huh, when I clicked on for CPU support list I didn't get a drop-down menu. All I got was a huge unsorted table that I then had to search through, using my browser find feature, and the board was nowhere on the page.
That board didn't ship with a BIOS to support your CPU. It's usually a good idea to make sure that the motherboard you want to buy is gonna be able to support the CPU that you want to buy without a BIOS update. Of course it seems your board can't support that CPU even with a BIOS update
