16 PowerEdge C5220 Technical Guide4 MemoryThe PowerEdge C5220 uses DDR3 memory to provide a high-performance, high-speed memoryinterface capable of low latency response and high throughput. The PowerEdge C5220 uses DDR3memory, providing high performance, a high-speed memory interface capable of low-latencyresponse, 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 isorganized 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) UDIMMsoperating at 1333MT/s and 1600MT/s. 8-sled version: PowerEdge C5220 supports 2GB, 4GB and 8GB regular form factor UDIMMsoperating at 1333MT/s and 1600MT/s.Note: Only E3-1200v2 series processors support a speed of 1600MT/s.Supported memoryTable 8 lists the DIMMs supported by the PowerEdge C5220.

All memory on all processors and channels run at the samespeed and voltage. By default, the systems run at the highest speed for the channel with the lowestDIMM voltage and speed. The operating speed of the memory is also determined by the maximumspeed supported by the processor, the speed settings in the BIOS, and the operating voltage of thesystem.Although the PowerEdge C5220 supports DIMM speeds of 1066MT/s, you can only purchase these systemswith DIMM speeds of 1333MT/s and 1600MT/s on Dell.com/PowerEdgeC.
