Crashes after setting RAM to 1600

[realism51]

Lets see if anyone can solve this one for me. Working with :
ASUS M4A87TD EVO - BIOS version 2001 (latest)
RAM - Corsair DDR3 4x4GB CMZ16GX3M4A1600C9 (CPU-z says max bandwith is 667Mhz)

Never had an issue until the day I changed the BIOS settings for the RAM to operate at 1600mhz. Playing CS GO and keep getting random crashes or freezes that send me through the reset cycle.
Frequency is set at 1600Mhz and Timing row is set at 41 like it should be. Voltage stays the same 1.50V --->1.500V

Rechecked made sure I had latest Bios, reflashed just to be on the safe side and still am having issues. I know there are no error screens or any sort of overheating going on, checked components and updates. all is in the green.

I know I can set my RAM back down and TRC to 34 but hey whats the point if you got the power use it right?

Some memory will not operate properly at 1600MHz @1.5v and needs the voltage bumped up a bit, to say 1.55v

You said 2001?
I am trying to fathom this, I think it may be because your motherboard doesn't support 1600, or like abekl said, bump it to 1.55 volts.

Motherboard supports up to 1600 http://www.asus.com/Motherboards/AMD_AM3/M4A87TD_EVO/#specifications
Tried looking at how to manual set the Voltage but couldnt find anything beyond the AUto setting, Hitting Enter on it wont let me select any voltage.

manually set voltage for RAM to 1.55 instead of 1.50 or auto, and seems to be holding steady
