R815 Memory Configuration Not Optimal
Hi, i recently upgraded the memory of my r815 from 32gb to 80gb following the guidelines of the Owner’s Manual page 93 but i'm getting this warning when boot up the server. Current memory configuration its as follow:
A1-A2-A3-A4 =8 GB dualrank 1333
A5-A6-A7-A8 = 2 GB singlerank 1333
B1-B2-B3-B4 =8 GB dualrank 1333
B5-B6-B7-B8 = 2 GB singlerank 1333
The particular points that lead to this configuration are:
- In case of mixed-rank population, first populate the DIMM with the
highest number of ranks (in sockets with white release levers).
- Mixing of memory sizes and ranks is allowed for flexibility.

Hello
I would suggest populating according to the example configuration on page 94 of the manual. It is noted by "a" at the bottom of the page. Populate all of your 8GB on CPU1 and all of your 2GB on CPU2.
Just because mixing is allowed does not mean it is an optimal configuration. You may continue to receive non-optimal messages, but the suggested configuration on 94 would be best.
Thanks
