Need help changing RAM settings.

[bowhawk000]

I have this mobo: http://www.newegg.com/Product/Product.aspx?Item=N82E16813128651
I have this ram: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231627

The ram is advertised at 1866, but my bios shows 1333. I have tried changing it to the advertised speed in my bios but have been unable to. Any help would be great. Step by step would be fantastic.

What CPU, that's the big factor (actually the CPU's MC)

Go into the BIOS and enable DOCP and select 1866 - if any problems try same and raise DRAM voltage to 1.575, if still problems raise CPU/NB voltage to 1.2
