Hi, i just bought a new comp and the motherboard runs my 1866Mhz at 1333Mhz by default.

CPU: i7 4790
Motherboard: Asus H97M-E (http://www.asus.com/Motherboards/H97ME/)
RAM: Crucial BLT2CP4G3D1869DT1TX0CEU Tactical 8GB Kit (4GBx2) (http://www.amazon.co.uk/Crucial-BLT2CP4G3D1869DT1TX0CEU...)

CPU-Z validation(idle): http://valid.canardpc.com/evnqfz

Picture of CPU-Z SPD:

As you can see there is no JEDEC for 1600Mhz.

With default NB(north bridge) frequency adjust according to ussage, if i set in UEFI RAM frequency to 1600Mhz the NB frequency stays at 4000Mhz which might overheat my motherboard and unnecesary energy consumption. I think this is because there is no JEDEC for 1600Mhz, i still haven't try with forcing 1866Mhz in bios cause im afraid of overheating the motherboard which doesn't have much heatsinks on.

I'm not keen on turning XMP on cause it interferes with i7 4790 Turbo i heard, but i might give it a try if you say it's fine.

FSB:D RAM ratio is 1:5, what is a good ratio for my pc?

What should i do, should i leave it at 1333Mhz so turbo and all Inter settings can run good or should i tweek it?

I'd just let Turbo and all Inter settings run good since Turbo does add a decent amount of speed.
