16GB DDR4-2400 ECC RDIMM
This 16GB DDR4-2400 ECC Registered RDIMM is built for HP server platforms that require PC4-19200 memory. It suits administrators expanding capacity in existing rack or tower systems to support virtualization workloads and reduce swapping.
Straightforward DIMM installation
The module seats in a standard DDR4 RDIMM slot and is keyed to prevent incorrect insertion. Ensure the server is powered down and unplugged; a common issue is mixing registered and unbuffered DIMMs in the same channel, which prevents the system from posting.
Verify registered ECC support
Confirm the server motherboard and BIOS support DDR4 Registered ECC memory at 1.2V before ordering. Check the qualified vendor list for 2Rx4 PC4-19200 modules and verify available slots match the desired total capacity.

Questions about this item
How can I confirm the 16GB DDR4-2400 ECC Registered RDIMM is detected and running at 2400MHz after installation?
Check the server BIOS or UEFI memory information screen; it should show 16GB capacity, DDR4-2400 speed, registered ECC operation and 1.20V voltage for this module.
What is included with the 836221-S21 compatible module and what must be sourced separately?
The package contains the single 16GB 2Rx4 DDR4-2400 RDIMM; any additional DIMMs, memory risers or server-specific brackets are not included and must be obtained separately.
Which capacity and rank configuration should I choose for a slot that requires a 16GB 2Rx4 DDR4-2400 registered ECC module?
Select this 16GB 2Rx4 PC4-19200 DDR4-2400 CL15 1.2V registered ECC RDIMM; it matches the specified capacity, rank, speed and voltage for that slot.
