Most successful business ventures are created out of smart business choices. If your Dell R420 isn't performing its best, the smartest and most efficient solution may be to expand its memory capacity. Expanding the memory in your R420 is a small investment that can yield big returns.

Dell PowerEdge R420 Memory Upgrade Options

The Dell R420 supports up to 384GB and can handle 12 dual in-line memory modules. Depending on the DIMM types installed and configured, the R420 can support speeds of up to 1600MT/s. With three memory channels per processor, the Dell R420 can support two DIMMs in each channel.

Tips for Upgrading Your Dell PowerEdge R420 Memory:

• If different DIMM speeds are mixed, all channels across all processors operate at the slowest DIMMs common frequency.
• Only one type of DIMM can be used in a system. UDIMMs and RDIMMs cannot be mixed.
• The supported memory DIMM type and speed is dependent on your current server configuration.
• DIMMs must be installed in each channel, starting with the DIMM farthest from the processor.
• DIMMs should be installed with the largest rank count to the smallest.
• Up to two quad-rank, dual-rank, or single rank DIMMs may be populated per channel.
• Upgrade to as much memory as possible at once. Expanding the memory fully will result in the best performance possible.
