  ah sorry it currently has 4 x 4GB dimms. What would the layout be if I were to reduce the 8GB dimms's by 2 to make a total of  4 x 4GB + 4 x 8GB dimms for the server? (also running on the latest bios) Chris   In that case you would want to populate the larger DIMMs first, so the optimal config would be: 8GB - 1,24GB - 4,5 Thanks
I have a dual proc r610 with currently 4 x 4GB(16GB total) Dimm's. I have 6 x 8GB modules I want to put in the server.  Whats the best layout I can do?
