UCS C220 M4 with Intel Xeon E5-2620 v4 processor(DDR4 2133Mhz) with 2400Mhz memories?

[markko.krause]

One client wants to buy UCS C220 M4 serverand they have described in the procurement materials Intel Xeon E5-2620 v4 processor and DDR4 2400MHz memories.

From Intel specifications I found that this processor supports memories up to 2133MHz. So will this configuration work also with 2400MHz memories or do we have to change memories to 2133Mhz?

If you use Intel v4 CPU with 2400 MHz RAM memories (...RV-A=) you can achieve 2400 Mhz speed when you use only two slots per channels (you can fill up to 16 of 24 slots).
