Dell PowerEdge R420 Server Memory "How To Guide" for RAM installation and configuration. In this video, we will go over all the different options including speeds, sizes and type of memory accepted as well as discuss best practices for loading & installing your memory modules.
The Dell PowerEdge R420 is a 1U server powered by dual Intel E5-2400 V1 & V2 series CPUs (LGA1356 socket). Part of the 12th Generation of Dell servers, the R420 is the next gen to the Dell PowerEdge R410 server. This system boasts 12 DIMM slots supporting DDR3 memory architecture. There are two types of memory for your R420 server: ECC Registered (RDIMM) and Load Reduced (LRDIMM). The key difference between ECC Reg and Load Reduces is the max capacity for your R420. The max installation is 384GB via (12 x 32GB) DDR3 PC3-12800R 1600MHz for ECC Registered Server Memory. However, LRDIMMs will provide double the capacity maxing out at 768GB via (12 x 64GB) DDR3 PC3-12800L 1600MHz Load Reduced Server Memory. A common question we hear. Does 64GB DDR3 ECC Registered memory exist? No. It does not exist so 32GB DIMMs will be the max for ECC Reg. There are 2 CPUs. Each CPU supports three Memory Channels. There are two DIMM slots per memory channel. This is important for loading the system properly. The RAM channels are color coded with white being the start of the channel. The best configuration for 2 CPUs would be 6 or 12 DIMMs for an even balance across the channels. We will discuss in more depth in our video and demonstrate how to load & install the DIMMs inside your PowerEdge R420 server.
