Need Help Overclocking Corsair Vengeance DDR3

What is up O.C.F

The kit in question i have is
Corsair Vengeance 4 x 4 GB (althought im only using 3 out of 4 dimms in tri channel)
Part #: cmz16gx3m4a1600c9

I can get it running at 1528MhZ (191 * 8) fine and recognising all 12GB, using the standard voltage and timing.
But as soon as i try to but the Ram multi to 10x windows does the old "12GB (8GB Usable) trick, and not mixture of timing (tried 10-10-10-31-2), voltages (1.54 - 1.66v) seems to work.
Im purely wanting to achieve the 1910MHZ Ram OC for rendering purposes and benchamarking, so any help would be appreciated.

EDIT: i got all 12GB to recognise with 11-11-11-31-2 timings so im just wondering where i should start with improvements?

I used to have OCZ Reaper DDR3 but they were 2GB dimms so i pulled them out.

MY CPU OVERCLOCK is as follows:
I7 920 do @ 4.01ghz ~ 1.275v
QPI/VTT: 1.36v
Uncore: 191 * 20 = 3820
RAM: Corsair Vengeance 12GB @ 1528mhz currently at 9-9-9-24-2 ~ 1.54v
MOBO: GAEX58-UD5

For 1800+ memory clock it will need much higher QPI/VTT like 1.5V and higher memory voltage ( or more relaxed timings like you already checked ). Higher capacity = more stress for memory controller = higher voltage requirements. Can also try to bump IOH voltage. Sometimes it helps to keep QPI/VTT voltage lower.
Personally I would set 19x200bclk. It's probably easier to stabilize and you can set 1600 memory clock. Later lower timings and set memory voltage higher. For this kit you will need ~1.35V QPI/VTT and maybe 1.60-1.65V memory voltage to run 1600 8-8-8 or 7-8-8 ( can try lower, don't know what IC is there ).

Ok so ive got it stable at 1910, @ 11-10-10-28-1 @ 1.6v (havent tested lower yet), qpi is @ 1.38, vcore is @ 1.275, ioh is @ 1.26v.... Does this sound ok? Passed 20 runs on linX

If it's stable then looks ok.
