Two stick of RAM being read as single channel

Hi I have 2 sticks of G Skill Ripjaws X 1866 RAM installed on the ASrock z68 Extreme4 with a i5-2500k. Even though the two sticks are being read as 8gb which is correct, when I go into BIOS it says it is running in single channel. I am under the impression that if I have two sticks it should be dual channel.


Also when I put in a RAM stick into slots 1 or 2 I get the Dr. Debug code 45. When I put a stick into 3 or 4 it boots up fine. If I put both sticks into 3 and 4 it boots up and the RAM is recognized. WIll this cause problems as the two slots are different colors. Also does this mean that my slots 1 and 2 are broken? If I put RAM into slots 1 and 3 or 2 and 4 I get the same error code. Will this mean that if I try to put in two more sticks for a total of 4 sticks of RAM it will not work?

If he read the manual, he wouldn't be putting the ram in the wrong slots.

Put the ram in slots 1 and 3, or 2 and 4. Being in the same color will enable dual channel for that mobo. Load up the xmp might stop the error code.

Maybe a better reply would have been "Check your manual, it states which slots to put the ram in." No offense.

The manual does not specify which slots to place the RAM in, only that if I want two install two sticks of RAm they should be in the same colored slots. My problem is that it only works when I put the RAM into slots 3 and 4, which are different colors.

What exactly is the xmp and how would I go about loading it?

It stands for eXtreme Memory Profile. Have you OC'd the CPU?

In the bios go to the OC section. In there will be a ram config. And somewhere in there will probably say load profile, select the xmp option. Have you changed any bios options?

No I got the error code on my first boot before changing any bios settings.
