Low Memory Benchmark Speed

Hi, I've got a question about my memory benchmarks in AMD Overdrive. Admittedly I'm not very knowledgeable about what these numbers mean exactly in relation to what the min-max values are for each category or what exactly they are measuring, however to me it seems that my computer scores atleast "decently" in all categories except memory. I have 8gigs of DDR3 2133 memory and I believe it should be scoring much higher than what is represented in AMD Overdrive. I've taken a screen of my score in Overdrive, my memory page in CPU-Z, and the store page where I got my memory. The rest of my specs are as follows.

CPU: AMD Athlon X4 750K Quad Core
MB: Biostar Hi-Fi A85W
GPU: MSI NVIDIA Geforce GTX 960

Could someone help answer if I'm right that my memory should be scoring higher? If so what can I do to fix it? Could it be bottlenecking my rig as stands now? Sorry if some of these questions are obvious I'm a complete novice with this sort of thing. If more information is needed about my rig id be happy to provide it assuming I can find it.

Run AIDA64 memory benchmark or Maxmemm and report back.

That said, I believe its fine and not bottlnecking anything regardless.

Alrighty thank you sir! I was just concerned cause I saw some people score higher with 4gigs of some slower speed ram and wanted to make sure I didn't mess anything up.
