R820 RAM 1866 Mhz running at 1333 Mhz

Hi,

I have a R820 equipped with 4 x E5-4627 v2.

I installed 48x32Gb RAM to attempt the max of 1.5Tb. 

The RAM I'm using is JGGRT:  Pc3-14900 DDR3-1866 mhz.

When I boot the machine I'm getting RAM running at 1333 instead 1866.

The CPU, as I found in intel website, supports 1866 Mhz.

Can someone tell me what I'm missing?

Thank you.

Hi,

Please I'm experiencing some issues with some RAM units. Can I replace defective ones (1866 Mhz)  with 1333 Mhz?

Thanks.

Hi Abidal,

 

That clock speed should be perfectly fine, especially since the rest of your memory is already being downclocked to match. You'll want to make sure other characteristics match though, such as rank and type of DIMM (LRDIMM, RDIMM, or UDIMM, for example).
