UCS B200 M3 memory speed

[ziutek]

We have recently installed a few new B200 M3 servers, fully populated with 24 x 16 GB (1866 mhz) DIMMs, 2 x E5-2697 v2 CPUs.

UCS manager shows the DIMMs properly in the inventory tab, but from the General tab, shows "Operating Memory Speed" of 1333 mhz (same speed in the boot messages.

Board Controller: 8.0

Firmware: 2.1.3a

CIMC: 2.1.3a

Anyone know why I am seeing the slower memory speed? What am I missing?

Thanks,

Joe

Joe,

Have a look at table 7 here:

If you're using 3dpc you'd be stuck at 1333, even if you're att 1866 DIMM and CPU.
