4 Memory
The PowerEdge C5220 uses DDR3 memory to provide a high-performance, high-speed memory
interface capable of low latency response and high throughput. The PowerEdge C5220 uses DDR3
memory, providing high performance, a high-speed memory interface capable of low-latency
response, and high throughput. The PowerEdge C5220 supports unbuffered ECC DDR3 DIMMs
(UDIMMs) only.
Each server contains four memory sockets for the single processor. The DDR3 memory interface is
organized into four DIMM slots, with up to two UDIMMs per channel in two configurations:
12-sled version: PowerEdge C5220 supports 2GB, 4GB and 8GB very low profile (VLP) UDIMMs
operating at 1333MT/s and 1600MT/s.
8-sled version: PowerEdge C5220 supports 2GB, 4GB and 8GB regular form factor UDIMMs
operating at 1333MT/s and 1600MT/s.
Note: Only E3-1200v2 series processors support a speed of 1600MT/s.
Supported memory

Memory speed
The PowerEdge C5220 supports memory speeds of 1600MT/s or 1333MT/s depending on the DIMM
types installed and the configuration. All memory on all processors and channels run at the same
speed and voltage. By default, the systems run at the highest speed for the channel with the lowest
DIMM voltage and speed. The operating speed of the memory is also determined by the maximum
speed supported by the processor, the speed settings in the BIOS, and the operating voltage of the
system.
Although the PowerEdge C5220 supports DIMM speeds of 1066MT/s, you can only purchase these systems
with DIMM speeds of 1333MT/s and 1600MT/s on Dell.com/PowerEdgeC.
