Ram compatibility problems

[Axel18]

Hello guys,

I installed a new ram stick(Kingston Hiperx Fury 1866 4Gb) in my computer: AMD APU 6800k, Gigabyte A88x, Kingston Hyperx Genesis 1866 2x2GB),

and i have some trouble with the frequency. The new stick is running at 1866 but the ram I've had installed already is now running at 1333, i can't change the settings from Bios like I used to to because it will not let the windows boot.

I noticed a thing, the older ram is running X.M.P at 1866 1.65V and the new stick at 1866 1.5v.

Can I do something to run all of them at 1866?

i wanted to rise the voltage to 1.65v but i don't know if it will damage the 1.5v ram stick.

I will try some settings, and move the sticks in the motherboard slots and come with the results. Also i read on overclockers.com a review, he managed to oc this at 2200 with 1.65v with low temps and no damage.

Ok a little update, Both genesis and fury can run at 2133, and i did rise the voltage at 1.654V and the genesis just doesn't want to pass 1333 without X.M.P, the xmp setting is not available with the third stick installed.

So right now i don't know what to do....
