Check your board on the Asus website to see if a BIOS upgrade fixed an issue such as this.

To improve compatibility, increase the memory voltage from 2.65v to 2.75v. This has helped Corsair and Crucial users, and may also help with your memory.

Also, double check your motherboard documentation to ensure that your memory is in the correct slots. On my Asus board, I accidentally put the memory side-by-side, which was incorrect. If yours is similar to mine, there should be a vacant DDR slot in between them. (On my board, the two correct slots are blue.)

Hope this is useful.
The only other thing might be too small of a power supply, but you should be safe unless you're using a high power graphics card or have multiple hard drives.
