DL380 Gen9 - The Operating Frequency is 1866MHz instead of 2400MHz

[Grinja]

Hi,

I see that 'Operating Frequency' is 1866MHz instead of 2400MHz.
DL380 Gen9
CPU x 2 = E5 2660 v4

Memory (18 out of 24) = 809083-091, 32GB ECC-Reg DDR4 2400MHz

System ROM Firmware = P89 v2.00 (12/27/2015)
Any idea why 'Operating Frequency' is 1866MHz instead of 2400MHz?

I found the problem.

Based on info from following table - https://support.hpe.com/hpesc/public/docDisplay?docId=emr_na-c05240460#N10085

3 DIMM per channel = 1866

So I removed 2 bars and it's solve my problem (now=2400MHz)
