R910 quad CPU 8x memory riser - memory population/layout
Hi everyone
We have a Dell R910 with 4 CPUs and 8x memory riser cards.
At the moment the server has 256GB memory, 4x 8GB RDIMMS per riser.
The team has requested an additional 64GB for this server to take it to 320GB but from the documents I've found I'm pretty sure that 320GB spread across 8 memory riser cards is not a valid configuration. I have a feeling that they will need to step up to 512GB.
Is there a valid memory layout for 320GB spread across 8 memory riser cards?
Thanks, B

Hi Robert. Thanks for the reply.
1) Is it possible to have the first 4 risers have 6 DIMMs leaving the last 4 risers with the existing 4 DIMMs?
2) Or is it possible to use different sizes? So instead of adding 64GB by using with 8x 8GB, could they do 16x 4GB so that each riser would then have 6 DIMMs (4x 8GB + 2x 4GB)?
Thanks
