I had a VI Formula with a 4770K and a H100i and 4.3 was as stable as I could ever achieve.
I sold my 4770k and messed up my mb by putting the dust cover on wrong and bent some
pins on the socket. I handed it in to a pc fix it shop, and they broke off 3 pins.
I sold a guitar, and bought a VII Formula as if I waited for the new X99 boards, my new 4790K CPU
and my Ram would not work in it. I got rid of the H100i and bought a XSPC AX240 WC system.
I am now almost finished with the build, I need one more fan and a adapter plate for the Phobya
200mm Radiator so I can attach the fan. I ordered some M3-55mm screws too, as the shroud
comes with nothing. Once I learn to OC better, I believe I will hit 5.0
Good luck with yours, whatever you decide to do !!!!!!!!!!
Here I was doing my 24 hour leak test. The 200mm rad had not arrived yet.
