The HPE ProLiant DL380 G7 (Generation 7) server comes standard with 6GB of Unbuffered memory and can support up to 384GB of Registered memory or 48GB Unbuffered memory (consisting of 12 of the 4GB dual-rank PC3-10600 UDIMMs). Please note that Registered and Unbuffered memory cannot be mixed in the same server.

To achieve the maximum memory configuration, you must use Registered DIMMs (RDIMMs). The DL380G7 supports up to 384GB of Registered memory for dual CPU models (or 192GB for single CPU models). This is accomplished by either six of the 32GB quad-rank PC3L-8500 RDIMM modules for a single CPU server, or 12 of these 32GB modules for dual CPU machines. Global One Technology offers the 384 GB kit to max out the memory on your Dual CPU DL380 G7 server. Also available, the more budget-friendly 192 GB kit for Dual CPU servers. The complete list of DL380 G7 memory options are listed below. Feel free to contact us via Live Chat with with questions.
