BIOS won't recognize right RAM speed

[noleknight16]

Hello! I am new to computers, just recently built one. I am using an ASUS P8Z68-V motherboard and 8GB G.Skill Ripjaw 1866MHz DDR3 memory. The BIOS recognizes the correct amount of RAM, but the speed keeps reading as 1648 and claims my "max" speed is 1600MHz. It doesn't even give me the ability to choose the correct speed, so I reset the BIOS to defaults and suddenly have the ability to manually choose 1866 as the speed. Upon bootup and checking the BIOS again, the speed reverts back to 1648MHz.

What's the deal? Is there some kind of voltage problem?

The maximum speed your MB will accept by default is 1600MHz.

It will allow overclocking the RAM to 1866MHz but you would have to go into advanced settings to do that. Check your manual for instructions on how to do that.

I occasionally get an error message when booting up. It is very similar to this picture I found. Is my RAM speed likely the problem?

Yes, exactly. It is attempting to overclock your RAM to 1866MHz and it isn't working properly.

Read your manual to see what it says about overclocking your memory, or just set it to run at 1600MHz.
