Restarts one time on every boot up - asus optimal mode

Hello :)

Some months ago I built my first homebuilt and everything seems to be working great, though I have one problem..

When I enter BIOS and it's on 'asus optimal'-mode, then everytime I boot up my computer, it will restart once before it reaches the windows logon screen, and then it will boot up normally. :o
However this does not happen when its on 'normal'-mode. But when it's on 'normal'-mode the computer only uses 1333 mhz RAM :/ and the processor is weaker aswell.
Though I've figured out how to change the RAM to 1600 mhz again.

This is the modes I'm talking about: (not my picture, just a random from the internet)

But does anyone know why I keep getting this one restart everytime I boot in the optimal mode?
I know it would be better just to OC myself, but I'm not really sure how to get a good stable OC and all.

You can see my system spec here:

Intel Core™ i5 Quad Processor i5-2500K 3,3GHz
MSI GeForce GTX 580
Noctua NH-U12P SE2 CPU
Corsair XMS3 DDR3 1600MHz 4GB CL7 Kit w/2x 2GB XMS3 modules, CL7-8-7-20, 1.65V
Corsair TX 950W PSU
