A client of mine has several PE R810 servers with 2 CPU's and 2 blanks (I don't think these were purchased with the FlexMem Bridges). Each server has 8x 32GB DIMMs, but the BIOS is giving an error about Memory Configuration Not Optimal. One of the servers has this configuration:
32 GB: A1, A2, B1, B2, C1, C2, D1, D2
Without the FlexMem bridges installed, I would think that the issue with this server is that DIMMs are installed in C and D and shouldn't be.
However, the other servers use this configuration:
32 GB: A1, A2, A3, A4, B1, B2, B3, B4
I've gone through the manual, but I don't see an example of a memory config for a server that only consists of 2 CPU's and 8 identical DIMMs, so that's why I'm thinking that this client simply purchased the wrong amount of DIMMs or perhaps should have purchased the FlexMem Bridges. All servers report 256 GB of installed RAM, but all of them force an F1 during boot to get past the Memory Config error. With only having 8 DIMMs, are they just going to have to live with hitting F1? Are either of those RAM configs worse than the other? They both are "non-optimal", but the first one isn't letting me configure any redundancy like Spare or DDDC but in a non-optimal state I don't think I want to mess with that anyways.
Any tips would be appreciated. Thanks.
