I built a new computer but didn't configure BIOS I just left everything default. I was watching a youtube video of a similar build and their utility showed a frequency of 2133.4 on their corsair memory. mine shows up as 1066.0 or 1066.4 (it changes).

Is theirs set at 2133.4 because they over clocked or do i have mine running slower than spec?

Here is the memory i bought and I still have time to return it if you think i should: https://www.amazon.com/gp/product/B0725QY9BJ/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1

The "D" in DDR4 stands for double. So when you multiple 1066 by 2, you get 2133, which is the default speed for DDR4. If your motherboard and CPU allows you to overclock, you can, but if you don't mind the gameplay you are it, just stick to what you have.

Thanks i guess they over clocked it. On passmark all of my benchmarks are way better than my memory score. Did I buy junk or is everyone else overclocking? Most of my scores are 96%. My memory score is 54%. Of the 7 memory tests "database operations" was 64%, "memory read uncached" was 59%, and "memory write" was 76%. I've got a terrible feeling i've done something wrong.

as you can see the memory score is not in line

DDR4 = Double Data Rate 4

"The transfer rate represents how many data transfers there can be in megatransfers per second (MT/s). Remember, in current main memory, Double Data Rate is used, where data is transferred twice per clock cycle at the I/O bus. Half the transfer rate tells us the actual clock speed of the I/O bus, where the I/O pins work at that frequency (DDR4-2133 has an actual clock frequency of 1066 MHz, for example). Memory bandwidth scales linearly with transfer rates, and higher transfer rates / frequencies decrease access latency since the memory controller works at the memory frequency in current desktop CPUs, and affect timings measured in clock cycles (use the equation (Timing in clock cycles / Transfer rate) * 2,000). Throughout this post, I will usually refer to memory frequency / transfer rate simply as "memory speed" or "DIMM speed"."
