Memory Frequency Improperly Set According To Memtest, But Not BIOS?

So I used XMP, looked over all the timings and frequency, and every appears to be set correctly. However, every time I run Memtest, it lists the frequency as 1774 instead of the proper frequency of 1866. Anyone have any idea why this might be?

  1. Might check you have the latest version of Memtest, but it is often known to have problems, it may be reading a set of timings from the SPD of the sticks, big thing is that you don't have errors when it runs

    I just got downloaded the latest memtest version two weeks ago, so I doubt that's the issue. Not really sure about the SPD. Any possible way I can know for sure what frequency my RAM is running at? Is the BIOS or Memtest incorrect?

    My issue with just testing it at 1774 is that unstable memory can be made stable by running at lower frequencies. In this case, the difference is pretty small, but I'd still like to make sure I'm getting what I paid for and that there aren't any nasty surprises down the road.

    Run CPu-Z through Win, look in the Memory tab and it will show true freq (which is half of spec as this is DDR (DOUBLE data rate) so if 1866 sticks it will show 933 or there abouts
