256GB Memory on B200M3 bundles

[scott-carr]

I'm trying to get to 256GB RAM on the B200M3 using the smart play bundles. These bundles either include: 1.64 GB RAM (8x8GB), 2. 128GB RAM (16x8GB). The challenge I am having is that the CCW tools leads me to beleive two things:1. Flling up all banks and channels will decrease RAM speed to 1066, 2. I cannot mix the 8GB and 16GB DIMMS.

I do not want to throw away modules or suffer a perfromace hit to get to the 256GB mark.

Any insight would be helpful.

Thanks.

Scott,

Hope this helps a little:

Memory Performance:

•When  mixing DIMMs of different densities, the highest density DIMM goes in  slot 0 then in descending density (ex: A0: UCS-MR-1X162RY-A , A1:  UCS-MR-1X082RY-A, A2: UCS-MR-1X041RY-A)

•Your selected CPU(s) can have some affect on performance
