ASUS CM1855 can't use XMP on memory - is it possible at all?

[Kai_1]

I have a CM1855 (https://www.asus.com/us/Desktops/CM1855/) and 2 sticks of DDR3 1866 (http://www.newegg.com/Product/Product.aspx?Item=N82E16820233536) that I'm trying to get up to 1866.

It seems my BIOS doesn't have the AI Tweaker menu tab though, so I can't find any XMP settings. I updated it to the last one released on the ASUS support site, but still no AI Tweaker tab.

Did I buy a motherboard that can't use this memory to 1866? Is there a way to do this manually without the nice BIOS menu?
Thanks for any tips,
Kai

It supports DOCP, so might look for that in the BIOS and try to run at 1600, as a prebuilt chances are the BIOS is locked and you are stuck at running at the mobos defaults
