UCS C220 M3 Memory DIMM 1333MHz & 1600MHz compatibility

[navin_rk3]

Hi,

   I have UCS C220 M3 server with 2 x E5-2650v2 2.6GHz processor and 6 x 8GB DDR3 1333MHz. 

Currently Cisco no longer ships this RAM so if I buy 10 x 8GB DDR3 1600MHz will it be compatible with existing DIMMs.

Regards,

Naveen

Hi Naveen

I assume your question is whether you can mix 1333Mhz and 1600Mhz Dimms ?

The answer is

For optimum performance, do not mix DIMMs with different frequencies. If you mix DIMM
frequencies, the system defaults to the lower frequency.
