HP 836220-B21 16GB DDR4 Registered DIMM

This 16GB DDR4 module is built for servers and workstations that require registered memory. It adds capacity to compatible platforms without needing a processor change. The 2400 MHz speed rating matches the specification for this part number. Buyers who need unbuffered desktop DIMMs or laptop SO-DIMMs cannot use this module.

288-pin registered DIMM installation

The stick fits a standard 288-pin DDR4 slot and the registered design places a buffer on the command bus. Systems that expect unbuffered memory will not post with this module installed. Verify the motherboard manual calls for registered DIMMs before fitting. Mixing registered and unbuffered DIMMs in the same channel is not supported.

16GB capacity at 2400 MHz

The single specification that decides fit is the 16GB density combined with a 2400 MHz registered DDR4 profile. If the platform demands a different density, speed or unbuffered operation this part will not work. Match the part number 836220-B21 to the vendor qualified list for the target server.
