HPE HP 684316-181 16GB 2RX4 PC3-12800R DIMM Memory Module

“DDR3 SDRAM server memory is available for use in a variety of HPE ProLiant server systems. As of now, it is no longer necessary to replace an entire bank of memory to ensure DIMM compatibility within a bank. As long as the spare part number for the replacement DIMM is the same as the existing DIMMs in the bank, they are fully compatible.”
