Hi everyone,

I am trying to upgrade my server memory, but I am getting the following error:

My initial set up was:

48GB (8GBx6)

Slots used are A1, A2, A3 and B1, B2, B3

The upgraded set up that is giving the below error:

144GB (8GBx18)

Slots used are A1, A2, A…9 and B1, B2, B3, B…9 (all of them)

Channels seam to match as all the RAM modules are of 8GB each. I am not sure what I am doing wrong. 

Thanks in advance.
