Can you please help me?

I just got a new set of G.Skill - F3-14900CL8D-8GBXM [specs]
I want to use them in my modded GA-EP45T-UD3LR mobo [specs] running a Xeon 5460 [specs] @ 400x9.5
BIOS is a modified F12e [this]

Currently running 1600/12800 sticks [FLGE85F-B8MF7 MEEH] @ 1600 1.8v 7-7-7-20

i reset bios and insert only 1 stick of Ripjaws in slot1 and it wont post...
shouldnt it start up with a setting like 333*9.5 / 1333 CL8 and then i could do my best to reach 466*8.5 / 1866 8-9-9-24 :O
