Hi all im doing my best to try and sort these problems i have myself but i dont seem to be having much luck im hoping you guys can help me out.With the rig i have im pretty sure performance wise i should be seeing a lot better,when i play games like skyrim,netherwinter all the cod series,dayz (which i know is only in the alpha stage) im not happy with how these games play as in they dont run smoothly ive updated graphics drivers sound drivers all the usual but all that games i seem to play have this they are far from smooth at all.Im not very clued up when it comes to over clocking ect i know i have standard mode,energy saving and performance mode on my motherboard which i have had a mess with but tbh i have no idea what to tweak and what to leave alone to make things better ect (i dont want to fry or break anything).I downloaded a program called CPU-Z and noticed my cpu was jumping all over the place anywhere from 800mhz to 3800mhz i was wondering if this was the problem is there anyway of keeping this to run at a stable 3500mhz/4000mhz my rig is as follows

ASRock Fatality Z87 Professional Motherboard
Intel i7 4770k @3.50ghz
Asus GTX 780 3GB
256GB Plextor M5 PRO Extreme SSD
2TB Toshiba HD
8GB Corsair Dominator Platinum 2400
Corsair H100i cpu cooler
SStone 850w PSU
Win7 Ultimate
BenQ XL2420T 120HZ Monitor

Any guidance on how to tweak my motherboard and make cpu stable would be greatly appreciated or anything that you may think that could help me out, sorry for been so illiterate but im getting there thanks in advance and im sorry if i posted in the wrong part of the forum.

When the cpu has little to do, it will run slower.
That is normal operation.

Your rig should not have any problem running games.
If you have not, turn on vsync. That will smooth out gameplay by delivering frames in sync with your monitor's refresh cycle.

You bought a "K" to be able to overclock.
A gradual simple raising of the multiplier in the bios from 35 to something in the 4.2 range will give you more compute power. So long as cpu-z does not show vcpu voltage higher than 1.3 you are not in danger of hurting your cpu.
You likely do not need the oc, but it couldn't hurt.
Test with OCCT.

When you built your computer, did you remember to put thermal grease between your CPU and your water block? Also, if you did put it on, how much did you use? Putting a bunch on can be just as bad as not putting on any at all in some instances.

I recommend Arctic Silver 5, it's available in most electronics stores such as Radio Shack and it works quite well for the price. Remember that when you apply thermal paste, the end result you want is a less-than paper thin layer across the surface. With the i7, you need to apply a thin, vertical line of thermal paste across the top of the processor and let the pressure of your water block spread it out for you. Additionally, if you have to redo your thermal paste, make sure to clean all of the old stuff off of both your processor AND your water block. Rubbing alcohol and cotton swabs work well for this.
