Yes, you will need to bump your DRAM volts a bit or set to what your RAM specifies, raise your NB frequency, leave the timings as is. The NB will overclock the CPU so you should lower its multiplier when raising the NB freq.
Check with Corsair for settings specific to your PC. See my system specs, I have my RAM at 1656MHz with careful BIOs adjustments.
Do these settings in small increments and check for stability each time.
