We're about to install a memory intensive application and will purchase a server for it. The server will have at least 4 CPUs, with multiple cores. While the application is memory intensive, the consultants we're speaking with said that 32GB should be sufficient. They also said that if I add more memory than that, the server will slow down because of the "extra wiring" to connect all of the memory. I'm not planning on putting VMs on the hardware so I don't need extra memory to partition for virtual machines. However I am concerned that 32GB may not be enough.
Does the consultant's assertion that more memory than I need will slow the machine down correct?
