Could ya tell me what memory part id number ya got ?
I see ya got KF556C40-16 <-- could ya check for this number at the box or memory modules it self please ! And post the FULL ID PARTNUMBER please from this memory.
I do not see this Partnumber ID in the list, so i think not whole partnumber is listed by the ID tool ya used unfortunally:

I have seen issues with the CPU ya got installed and "sometimes " a downclock from CPU could help.
Ya need to downclock cpu in bios about 200Mhz lower, this means from 5400Mhz to 5200Mhz
Also make sure ya got good cooling/airflow for this cpu and in case !
Those cpu's run high temps very easy (80+ Celsius) and could throttle speed / performance
,and also could cause errors for other hardware.
If ya got Temp issue you should lower CPU Mhz to 5200Mhz or even lower !!!
Update us please !
