Get 1800 Ram To Operate at Rated Speed?

Corsair Vengeance 8GB DDR3 CMZ8GX3M2A1866C9
Asus M4A785T-M Mobo
AMD Phenom II X4 965

How do I get this kit to operate at 1800?

CPU-Z is reporting 803.6 mhz, I had to go into bios and manually change it to 800 mhz. I understand DDR and it is at 1607.2

I changed timing settings to 9,10,9,27

What do I have to change to get it to run at 1800?

More about 1800 operate rated speed
  1. crank the mhz up to 900
  2. it doesn't give me the option beyond 800 mhz.
  3. According Asus website
    your mobo just support 1800(OC) it means you need find in the bios memory frequency / memory FSB, That's have option [1800], while in the bios not show 1800 you need overclock it via FSB CPU, say your FSB at 200 that need raise to 240. and this is a problem of BE cpu, some time is not strong with a high FSB. because based cpu overclock use multiplier and small raise FSB.
    Raise fsb cpu at 240 , the ram will run in 1800, of course, by loosening the timings and raise the ram voltage
  4. The only option is gives me that allows a setting of 240 is the CPU/HT ratio I set it to 240 and it does not POST. The bios also has a setting that I can choose the % of overclock 2, 5, 8 and 10%. I set it to 10% and it gave me over 1700 mhz on the RAM. As soon as I started Prime the system crashed. Do I need to increase the voltages for it to be stable?
