Low memory clock on Lenovo LOQ

Hey there!
I was fine-tuning my new Arch install and I've noticed that my laptop's RAM seems to be running for some reason on lower clock:

lshw -c memory
...
  *-memory
       description: System Memory
       physical id: 28
       slot: System board or motherboard
       size: 16GiB
     *-bank:0
          description: SODIMM Synchronous 5600 MHz (0.2 ns)
          product: M425R1GB4BB0-CWMOD
          vendor: Samsung
          physical id: 0
          serial: 0462BD13
          slot: Controller0-ChannelA-DIMM0
          size: 8GiB
          width: 64 bits
          clock: 1305MHz (0.8ns)
     *-bank:1
          description: SODIMM Synchronous 5600 MHz (0.2 ns)
          product: M425R1GB4BB0-CWMOD
          vendor: Samsung
          physical id: 1
          serial: 04633966
          slot: Controller1-ChannelA-DIMM0
          size: 8GiB
          width: 64 bits
          clock: 1305MHz (0.8ns)

If I understand the output correctly, my RAM is running on 1305 MHz instead of maximum 5200 MHz (speed limited by my CPU - I have Intel i5 13420H). Could anyone tell me if I understand the output correctly, and if yes, what can be done about this "issue"?
