18 PowerEdge C6220 Technical Guide
4 Memory
The PowerEdge C6220 uses DDR3 memory to provide a high-performance, high-speed memory
interface capable of low-latency response and high throughput. The PowerEdge C6220 supports
registered ECC DDR3 DIMMs (RDIMM) and unbuffered DIMMs (UDIMM); standard-voltage and
low-voltage DIMMs are both available.
The system contains 16 memory sockets split into two sets of eight slots, one set per each
processor. Each eight-slot set is organized into four channels of two memory slots per channel.
The DDR3 memory interface consists of four channels, with up to two RDIMMs or UDIMMs per
channel. The system supports 4GB UDIMMs and 4GB, 8GB, 16GB or 32GB RDIMMs. The memory
mode depends on how the memory is populated in the system.
Supported memory
Table 8 lists the DIMMs supported by the PowerEdge C6220. For the latest information on

Memory speed
The PowerEdge C6220 supports memory speeds up to 1600MT/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.
