8GB DDR4-2400 registered ECC RDIMM with CL15 latency for server upgrades
This is an 8 GB DDR4 registered DIMM rated at 2400 MT/s with CL15 latency and 1.20 V operation. It uses a 288-pin form factor and carries ECC protection for data integrity in server workloads. The module is built with major-brand DRAM and matches IBM part number 46W0821.
It fits administrators expanding memory in compatible IBM platforms that require registered ECC DDR4 modules. Builders needing unbuffered UDIMMs, higher frequencies, larger capacities per stick, or non-ECC memory for workstation boards should look elsewhere.
Align the notch with the keyed slot and press until the latches click; the registered buffer adds negligible physical effort. Common issues arise when mixing registered and unbuffered modules or populating slots in an order the system firmware does not support.

Yes, the 288-pin DDR4 form factor matches standard registered DIMM slots used in compatible IBM servers.
The module uses a 1Rx4 organisation; mixing ranks in the same channel depends on the server memory controller, so check the system documentation.
In the server BIOS or OS memory utilities, verify the reported speed shows 2400 MT/s and CAS latency reads CL15.
