Memory subsystem
The PowerEdge R550 supports up to 16 DIMMs, with up to 1024 GB of memory and speeds of up to 2933 MT/s.
The PowerEdge R550 supports registered DIMMs (RDIMMs) that use a buffer to reduce memory loading and provide greater
density, allowing for the maximum platform memory capacity.
Topics:
• Supported memory
• Memory speed
Supported memory
The table below lists the memory technologies supported by the platform.
Table 3. Supported memory technologies
Feature PowerEdge R550 (DDR4)
DIMM type RDIMM
Transfer speed 2933 MT/s
Voltage 1.2 V (DDR4)
The following table lists the supported DIMMs for the R550 at launch. For information on memory configuration, see the Dell
EMC PowerEdge R550 Installation and Service Manual at www.dell.com/poweredgemanuals.
NOTE:
Maximum memory speed supported on the system depends on the processor specifications. So, while the DIMMs
supports up to 3200 MT/s, the processor may not support this memory speed. Please refer table Supported processors.
