I7 930 OC help

Hi everyone. I was hoping you guys could help me out here

Specs

CPU: i7 930
MOBO: EVGA x58 SLI LE
RAM: Corsair Dominator DDR3 2 x 4GB @ 9-9-9-25 1T @ 1460mhz (1333mhz sticks, but runs @ 1066 default)
GFX: 2 x MSI GTX465
Cooling: h70
PSU: TAGAN Turbo 700W

I recently OC'ed my 930 to 4.0ghz @ 22x183 (turbo'd) and got my RAM timings down to the 9-9-9-25 (it was 11-11-11-30) for the longest time. Im having problems running my games. It feels like my comp is running a bit sluggish when loading them. COD4 for example sits at the initial loading screen for a bit and then finally loads up

Heres my bios setting right now

Any help would be appreciated. Im pretty sure its a voltage problem, but im new to the whole OC'ing scene so i cant pinpoint exactly what it is.

Little extra info:

I used to be able to run Crysis on my old OC setup, but i decided to tighten my ram timings because i didnt like the 11-11-11-30 setupd. Before i changed it, i created an OC profile for my 465's and specifically tailored it so that it could run at its max in Crysis. Now when i use that same profile in Crysis, my screen tweaks out, and i get hard locked and have to reset my comp.

When trying to OC, much of the time 1 of my sticks (4gb) wouldnt get recognized in windows so i had to find a QPI setting that would enable me to OC to 4.0ghz, keep my 9-9-9-25 timing and enable full access to my ram. QPI #183 was what i came up with.

Hopefully you guys can take a look at my settings and figure out what would probably work the best.

I am on my computer 24/7 so i will reply back to any questions you guys have for me. Its lights out for me right now, so ill be back in 7-8hrs. THANKS!
