Low RAM benchmark scores

I recently built my computer, and found running memory benchmarks that i consistently got low scores in comparison to equal and lesser hardware; after days of trying to find a solution/explanation to this i've resorted to asking here for an answer.
My relevant specs are:
FX 6300 CPU @ 4.3GHz (multi)
M5A97 R2.0 motherboard
Corsair Vengeance LP 2133MHz RAM @ 10-9-9-27

As an example, on MaxxMEM my memory scores were:
Copy - 12205MB/s
Read - 12734Mb/s
Write - 6514MB/s
Latency - 55ns

Comparing to dozens of other users' scores this is about on par with 1333-1600MHz memory.
Every benchmark i try, Performance Mark, 3D Mark, Geekbench 3, i get much lower scores than i'd expect to. I've tried running at other settings such as 1600MHz 9-9-9-27 yet i still score much lower than i should in every application.
Can anyone lend me a hand here and explain why this is happening?
Other possibly relevant details:
CPU/NB freq - 2200MHz
Command rate - 1T

Are you comparing against similar AMD systems? or tossing in Intel rigs - also are the sticks running at 2133? Can check CPU-Z, if indeed at 2133 , in CPU-Z in the memory tab it will show the freq as 1066 (it DDR so DOUBle data rate) 1066 x2 = 2133.....if it shows 667 then you are at the mobo default of 1333

Atleast with my MaxxMEM score i've compared to other AMD systems and found mine was lower.
Yes it is running at 2133MHz.

What actual set of Corsair LP, it may in part have to do with the weird timing setup

CML8GX3M2A2133C11B It's meant to run at 2133MHz 11-12-12-28, but as i said i tried a variety of other settings and the problem persists.

the difference between 1333MHz DDR3 CAS 9 and 2133MHz is for instance 10% , the "issue" is in the FX processor

My problem does not lie in confusion over a low increase, it's that compared to memory of equal spec it has much worse scores.
If you have any evidence to back up your claim that the AMD processor is the problem, by all means post it.

Although irrelevant to my problem, interesting, i had no idea FX processors had such slow communication speed with their L3 cache; i guess that's why they gain such performance increases from the CPU/NB frequency.
I still believe the inferiority to Intel in a lot of applications is outweighed by the budget appeal AMD FX poses however.

Marketing trick- in order to increase the frequency ,which is marked on the boxes, they decrease the speed by increasing the latencies.
