Brand new mobo: GA880-GA-UD3H
CPU: Athlon II x3 455
Memory: 8GB (4GBx2) Patriot Sector 5 G 1066/1333EL (PGV34G1333ELK)

When I boot, I get the error in the title: "The System has experienced
boot failures because of overclocking"

Except... I'm not overclocking, all memory timings are set to "Auto"
and/or "SPD".

How can I get rid of this? The memory passes the Windows 7 memory test.

If it helps, I'm using the on-board Radeon 4250HD.
