Memory Performance
When configuring your server, consider the following:
• DIMMs within the blade can be of different speeds, but all DIMMs will run at the speed of the DIMM
• No mixing of DIMM type (LRDIMM, RDIMM, TSV-RDIMM) is allowed.
• Your selected CPU(s) can have some affect on performance. CPUs used must be of the same type.
• Mixing DIMM ranks and densities can lower performance.
• Unevenly populating DIMMs between CPUs can lower performance.
