CPU Overclocking advice?

[snelzzy]

My computer still had parts from 2008 installed in it.. so I finally decided to upgrade. I would love to overclock it for optimal performance but sadly I lack the proper knowledge.

Hardware: (Links included)

• 
  ■ CPU: Intel Core i7-3930K
  ■ CPU Cooler: CORSAIR H80i Water Cooler
  ■ Mobo: ASUS Sabertooth X79
  ■ RAM: G.SKILL 16GB (4 x 4GB) 1866 (PC3 14900)
  ■ PSU: Antec TruePower Quattro 1000W
  ■ GPU for monitor 1: GIGABYTE GeForce GTX 670
  ■ GPU for monitor 2: HIS Radeon HD 4890 Turbo+

I'd like to have the CPU at 4.2GHz? or whatever anyone, more knowledgeable than myself, might suggest for the highest stable setting.

The timing on the ram was different in the BIOS than listed. Can I just change those to what they are supposed to be and call it good?

Also, Should I attempt to OC my main GPU?

I will be more than happy to answer any questions to the best of my ability
Thank you in advance,
Jonathan

the first thing you should do is set your ram timings and speed to its proper settings otherwise you will experience instability a lot easier, the best thing for you to do is to read up about overclocking heres a guide you might find handy http://www.overclock.net/t/1189242/sandy-bridge-e-overclocking-guide-walk-through-explanations-and-support-for-all-x79-overclockers
