I have just ordered a new Dual CPU Dell T610 server with 8GB ram included.
The server has 12 memory slots (3 channels per CPU, 2 banks per channel).
I want to add memory to it (I intend to add RAM from Crucial as I have always had good experiences with them) - but I am getting confused with 'Memory Balancing'.
My intention was to upgrade as follows:
Already included (4 x 2GB)
Add 4 x 4GB
Total: 24GB
Reading http://www.dell.com/downloads/global/products/pedge/en/server-pedge-installing-upgrading-memory-11g.pdf I am getting confused!
I think I arrange as:
Channel 1: 4GB 2GB - 2GB 4GB
Channel 2: 4GB 2GB - 2GB 4GB
Channel 3: 0GB 0GB - 0GB 0GB
What would I do if I wanted to up to the maximum (for SBServer 2011) of 32GB?
I presume:
Channel 1: 4GB 2GB - 2GB 4GB
Channel 2: 4GB 2GB - 2GB 4GB
Channel 3: 4GB 0GB - 0GB 4GB
But would this be imbalanced? And does it matter?
Answer
Just rip out the 4x2GB modules and put in 6x4GB modules - the price won't be much more and it'll work optimally plus leave you with some modules to ebay and a cleaner system to upgrade later if needed.
