Does anyone know how to set the clock multiplier in Asus Z87 Pro BIOS? I see the option for CPU Graphics voltage but not the multiplier setting. I can do it in Intel extreme tuning utility but it's not a permanent solution.

p.s. in case you wonder why OC HD 4600, it's not for gaming, I just want to maximize the performance for madVR.
 
There's no multiplier setting under my Asus H77 BIOS, you can specify the GPU Boost option, and the iGPU max frequency (in 50 MHz increments).

I have those selected and set to 1350, and can confirm via Intel Extreme Tuning that the GPU hits 1350 like I have it set to.

EDIT and don't be afraid of gaming on it: at 720p it's quite capable with mainstream games at low/mid settings. Looks about the same as an Xbox 360. Your TV's input lag is more likely to be a factor preventing gaming enjoyment than the HD 4600 :D

I overclocked it to 1.6Ghz (stock is 1.25Ghz) in Intel extreme tuning utility and found zero improvement in performance in madVR. I am getting around 500 frames drop in 20 seconds of playing with Lanczos 3, Jinc is worse. So it looks like dedicated graphics is a must in this case.
