Help manually setting ram freq on gigabyte motherboard

[ScorpioW]

Motherboard : H77-D3H
http://www.gigabyte.com/products/product-page.aspx?pid=...
RAM :16gb 8x2 F3-1866C9D-16GXM

Ok so im trying to setup this new pair of 1866 rams and im having trouble . So ill explain what happened and what i did in points.

• 
  By default the ram is set to 1333Mhz when i got in bios.
  I read some posts mentioning i need to set my freq and 4 number thing manually.
  I managed to set the 4 number manually but i cant change my frequency to more than 1600 cause the multiplier maximum is 16x.
  So i tried the profiles already in there but both profiles have 1600 frequency not 1866.

My question would be how do i increase the multiplier number in the bios as my maximum is 16x, i cant seem to be able to get higher. However, in the motherboard website it mentions i support Ram up to 2200 OC and this one is 1866 so i suppose it should work. Im just not sure how. Also im having weird crashes in games, like the 1 that says nvidia kernal driver stopped working and recovered. I Looked up some posts about this and they mention i need to set my ram specifications into my bios which im failing to do.

Thanks in advance

From the page of the Motherboard:

Support for DDR3 2200(OC)/1600/1333/1066 MHz memory modules

You reach the top speed of ram at 1600 with default clock speed that's why you dont have a memory multiplier to get it over 1600 or a XMP profile, but you could reach up to 2200 only by increasing the base clock speed (and thus overcloking the CPU).

The crashes maybe are because you change the ram speed but dont modify the CAS settings, choose a XMP profile of 1600 and pass a ram test to check if you are getting any error

And to get the memory just modify the base clock from the default value (probably 100) to 116 if you board allow you (with a x16 multiplier you get 1856) but take into account that you are also overcloking the CPU by that amount.

I dont want to overclock my cpu..so i guess ill RMA it and get a 1600 pair
