Dell PowerEdge T360 Installation and Service Manual

The following are the recommended guidelines for installing memory modules:

• All DIMMs must be DDR5.
• If memory modules with different speeds are installed, they operate at the speed of the slowest installed memory module(s).
• Populate memory module sockets only if a processor is installed.
  • For single-processor systems, sockets A1 to A4 are available.
  • A minimum of 1 DIMM must be populated for the installed processor.
• In Optimizer Mode, the DRAM controllers operate independently in the 64-bit mode and provide optimized memory performance.

  Table 1. Memory population rulesThe below table describes the memory population information.

  Processor	Memory population	Memory population information
  Single processor	A{1}, A{2}, A{3}, A{4}	1, 2, 4 DIMMs are allowed

• Populate all the sockets with white release tabs first.
• Unbalanced or odd memory configurations result in a performance loss, and the system may not identify the memory modules being installed. Always populate memory channels identically with equal DIMMs for the best performance.
  NOTE:Equal memory modules refer to DIMMs with identical electrical specification and capacity that may be from different vendors.
