Best memory configuration for 2 R710's

Hi all,

After a bit of advice, I have 2 R710s and a total of 30 memory sticks.  12 of those are 8gb ecc and the remainder are 2gb.

I currently have both servers running 60gb memory with the following configuration; 6 x 8gb and 6x 2gb.

I could possibly get my hands on another 10 x 8gb sticks that are the same, after a bit of advice on best / max configs for the memory I currently have and what I could achieve with the additional 10.

I'm fairly certain that with the additional 10 I won't be able to have an identical setup across the two servers.

Thoughts / advice please?

Thanks

Re: Best memory configuration for 2 R710's

Shank89,

With the number of dimms you have, as well as looking at supported configurations, I would suggest loading A1-6 and B1-6 with the 8GB dimms in one server, with the remaining slots with 2GB dimms. That would use 12 8GB and 6 2GB in that server. In the next server I would load A 1,2,4,5 and B 1,2,4,5 with 8GB dimms, and then A7, A8, B7, and B8 with 2GB dimms, or if you want to use all channels you could go A1-3 and B1-3 with 8GB dimms and then the remaining slots with 2GB dimms, both would result in 72GB.

That would give server 1 108GB and server 2 with 72GB, unfortunately leaving 2 8GB dimms and 8 2GB dimms unused, or if you use all channels on server 2 it would leave 4 8GB dimms.

The problem is that the channels must match, so it is the number of specific dimms limiting us. If you were to add an additional 2 8GB dimms, totaling 24, you would be able to use all your dimms. With 8GB dimms in A1-6 and B1-6 and the remaining with 2GB dimms, both servers would be at 108GB.

Hope this helps.

Re: Best memory configuration for 2 R710's

Sorry I misunderstood and thought you were adding the 10 8GB and wanted to know the config with those included.

With your current memory (12 8GB and 18 2GB) you would use 6 8GB dimms in A1-3 and B1-3, and then 6 2GB dimms in A4-6 and B4-6. It would result in 6 2GB dimms being unused , with 60GB total per server.
