Capacity and Purpose
This is a 16 GB DDR4 registered ECC DIMM built for servers and workstations that require error-correcting memory. The module runs at 2133 MHz with a CAS latency of CL13 and uses a dual-rank x4 organisation. It is not suited for desktop boards that accept only unbuffered non-ECC memory.
Compatibility Check
Verify that your motherboard supports registered DDR4 DIMMs with ECC and can operate at the PC4-17000 data rate. The stick uses the standard 288-pin layout and draws 1.2 V, but some platforms limit registered memory to specific slots or population rules. Buyers who need unbuffered modules or a different speed grade should look elsewhere.
Build and Daily Use
The module is assembled with Hynix chips in a 2G x 72 configuration and carries the manufacturer part number HMA42GR7MFR4N-TF. Registered signalling reduces electrical load on the memory controller, which helps stability in multi-DIMM server configurations. The standard pinout ensures it seats firmly in any compatible 288-pin DDR4 slot.

Questions about this item
Does the 288-pin DDR4 module ship alone, or are any brackets or cables included?
The module is supplied as a single 16 GB registered DIMM; no brackets, cables or additional hardware are included.
How do I decide between the CL13 and CL15 latency figures shown for this 2133 MHz stick?
The part is rated CL13 at DDR4-2133; the CL15 value reflects a secondary timing and does not represent a separate version to choose.
What does the PC4-17000 rating mean for actual throughput in a server?
PC4-17000 indicates a peak transfer rate of 17 GB/s per module at the rated 2133 MHz speed.
