Does anyone know how I can change the memory speed on this motherboard to something greater than 1333MHZ?
http://www.asrock.com/mb/overview.asp?cat=Specification...

I have 2 x 4GB sticks of G.Skill Aires 1866mhz RAM and I am using an i5-2500K processor.
The only memory options in the UEFI BIOS is AUTO, 1066MHZ, and 1333MHZ. I ought to be able to at least run the memory at 1600MHZ, shouldn't I?

Enable "XMP" profile in BIOS, save and reboot your PC, after it should run at 1866.

Make sure you have the latest BIOS, and may have to set up manually, the mobo 'officially' supports up through 1600 sticks, so may not have XMP support for 1866 or higher

The manual memory specifications read that Ivy Bridge processor is needed for DDR3-1600MHz. A Sandy Bridge i5-2500K processor may not be able to go over DDR3-1333MHz.

Haven't seen a 2500K yet that couldn't run 1866/2133 and have worked with over 100 of them

My original BIOS (1.70) did not have the "Enable XMP Profile" available. So I updated to the latest BIOS (1.90). Unfortunately, that option still isn't available even though the MB manual mentions it in the BIOS section.

@ Calvin7
That would be my thought too, except for the fact that I had this i5-2500K and the same memory in a Gigabyte MB previously, and I was able to run the memory at 1866mhz.

Try setting manually to 1600, 9-9-9-24, 1.5

There's no option to set the speed (1600) in the BIOS's "OC Tweaker\DRAM Configuration". I searched the entire BIOS for some way to change it. There are every DRAM teak imaginable, but not that.

You should have XMP (eXtreme Memory Profile) option too. What does XMP profile 1 or 2 give you?

That's the problem. I don't have a XMP (eXtreme Memory Profile) option. I just fired off a support ticket to Asrock and asked them what was going on.

How can I try manually when there's no option to change the memory freq?

Not a peep from Asrock yet. Maybe I better swap this board for another one while I still can.
