I would list your board model number and check for a bios version at the post screen. You may need a bios update to run your cpu. You may also have a ram stick that isn't all the way in the slot. Try reseating all your ram sticks.
Your motherboard has a specific model number and version. My asus h61 has about four versions with this chipset. If you're not sure, download cpuz, a free small file that will id your motherboard, bios, ram, etc.
