Hello ElectroStingz,
Thanks for replying. I knew that non-k would be limiting, but not this much. On my other machine I have the i7 4770 non-k running fine at 39-39-39-39. The motherboard is an Asus z87-a though.
I thought that the GA-Q87M-D2H would also allow me to run the turbo on the highest ratio since the feature is mentioned in the manual. It is mortifying that my 4790 is running slower than my 4770 (3792MHz (38x99,79MHz) vs 3978MHz (39x102MHz); 186MHz slower) when it matters
Note that I am not whining about a non-k cpu not being the same as a K cpu but about unnecessarily losing about 5% of potential running speed that it should be able to.
Are you saying that my only hope lays within software in Windows?
I was holding back on installing windows 7 because I have an OEM version (locked on motherboard) and because I am still waiting for some hardware to arrive. It seems I need to install the OS as trial to test it.
