I just bought a new computer. I've got a Gigabyte P55A-UD4 motherboard, an Intel i5 750 CPU and Kingston HyperX 4G memory which can run at 1600 MHz with XMP enabled but runs at 1333 MHz otherwise. If I try to enable XMP by setting it to Profile 1 in the BIOS, the computer freezes during POST and won't boot. I've updated my BIOS to the latest version but that didn't help. Here are my RAM settings before and after enabling XMP:
Thanks,
Adam
