one question for server USC B200 M4

[ipmitool1]

Hi,
I have one question for your server USC B200 M4.
According to your Spec Sheet, page14. It's defined the RDIMM supported 2DPC 2133MHz, but according to Intel released spec and it should be reduce to 1866 when install 2DPC memory.
Is it a spec issue? Why your server can support to 2DPC 2133Mhz?

Thank you

Can you please post the Intel reference; I don't think that Cisco is deviating from any Intel specifications.

B200-M4 uses

Registered ECC DDR4 DIMMs (RDIMMs) or load-reduced ECC DDR4 DIMMs (LRDIMMs)

The frequency of DDR4 LRDIMMs remains the same whether it is used in 1 DPC or 2 DPC configurations.
