Hello... the memory controller is on the CPU... so you need to match the specs for your CPU... what CPU are you using?

 

[ghavier]

My cpu is a i7 4790 non k

 

[Ironsounds]

Hello... Your CPU memory controller specs at DDR3-1333/1600, DDR3L-1333/1600 @ 1.5V

I know that, but i want to know if the motherboard is compatible with that ram. I heard that i7 cant handle ddr3 2133 mhz

Hello... the Motherboard does not use the ram... But it does provide a electrical path to the CPU... so there is going to be a freq limited/signal interference path to get there... B / and states up to 3100Mhz

So, if i buy this. The ram will not be Recognized. Is that what you are telling me?

 

[Ironsounds]

Hello... Well it can and cannot... Memory can typically run at lower speeds than the spec'd maximum... the CPU/MB will make several attemps at Boot to find compatible communication settings for them... I would think that you will find the first successful Boot at 1333 or 1600 Mhz. B / But don't expect the RAM/MB to dictate the speed to the CPU... the CPU is the one that needs good communications settings with the RAM and is also in control of things here. B )

Then you will be able to OC or XMP... and find what settings work or don't work... if you "create' a bad setting then just remove your MB battery, clear the CMOS, re-install the battery and the next boot will bring you back to a safe 1333/1600 or previous default.
