"Locked" on lcd poster Asus Rampage Gene 2

Heres my system, i just assemble it the other day..

i7 920
Asus Rampage Gene II x58
G.Skill Trident 3x 2gb Tri Channel 1600
Palit gtx 260 216sp
corsair 750w
antec 300


The first time i turned it on it worked but i noticed the mobo rated 1333 on my memory which was i think 1600..

I installed windows 7 successfully after this first boot. (cpu on stock cooler)

After a day, i DISASSEMBLE everything to install a Prolimatec Megahalem.. then when i turned it on, it posts a "LOCKED" message on the LCD poster..

I never overclocked anything because i dont know how yet and it was just a first run of the system.

Please help me

This is what i tried to far
1. removed cmos battery, video card, all power, waited a couple of minutes, installed everything again (didnt work)
2. removed cmos battery and all of the above, waited a couple of minutes, installed one Ram (2GB) in A1 slot and cmos battery, waited another 10minutes or so, then installed the other parts... no luck still locked
3. press CLR CMOS at the back panel while in locked state and turned the pc on again (didnt work, still locked)
4. used only one stick of ram, or all rams on each of the items above (no luck)
5. i tried to remove the prolimatech megashadow and install the stock cooler but no luck, still locked.
6. also tried to put the video card on the second slot but no luck still

I havent tried to buy a QVL rated ram with 1333 speed. i was thinking it worked the first time.. i might get it to work again...

HELP GUYS PLEASE

any ideas?
