DDR4-2400 CAS-17-17-17 for E5-2600v3

[Streym]

Hi,

I have DL160 Gen9 with 2 x E5-2620 v3 cpu's  and 2 x HP 16GB (1 x 16GB) Dual Rank x4 DDR4-2133 CAS-15-15-15 Registered Memory Kit  (726719-B21) 

I want to add extra memory to this server, but HP memory for e5 v3 cpu  (i.e. DDR4-2133 CAS-15) is twice as expensive then HP memory for e5 v4 cpu.

Will memory for E5-2600 v4 series work with this CPU? 

for example: HP 8GB (1x8GB) Single Rank x8 DDR4-2400 CAS-17-17-17 Registered Memory Kit (805347-B21)

I guess DDR4-2400 should not have problems running on 2133 rate, but worried about CAS latency. 

Or maybe BIOS won't let to run this memory at all? 

thanks!
