4 Memory

The PowerEdge C6220 II uses DDR3 memory to provide a high-performance, high-speed memory

interface capable of low-latency response and high throughput. The PowerEdge C6220 II supports

registered ECC DDR3 DIMMs (RDIMMs), low-voltage DIMMs (LVDIMMs), unbuffered DIMMs

(UDIMMs) and load-reduced DIMMs (LRDIMMs).

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, LVDIMMs,

LRDIMMs or UDIMMs per channel. The system supports 4GB, 8GB, 16GB or 32GB RDIMMs and

LVDIMMs, 4GB UDIMMs, and it supports 32GB and 64GB, 1600MT/s LRDIMMs. The memory mode

depends on how the memory is populated in the system. The PowerEdge C6220 II does not

support 1866MT/s in two DIMM per channel configurations.
