SK hynix HMA42GR7AFR4N-TF 16GB DDR4 ECC Registered DIMM
A 16 GB DDR4 ECC registered DIMM running at 2133 MHz with CL15 latency and 1.20 V operation
- ECC protection guards data integrity in critical workloads
- Registered signal processing reduces electrical load on the memory controller
- Low 1.20 V voltage cuts power draw per module
- 288-pin DIMM fits standard DDR4 server slots
- RoHS compliant build meets environmental standards
Server memory module
This SK hynix module provides 16 GB of DDR4 capacity in a single registered DIMM. It is designed for servers and workstations that require error-correcting code memory for data integrity.
Compatibility checks
Verify that your motherboard supports registered DDR4 DIMMs and accepts a 288-pin form factor. The system must also be configured for 1.20 V operation and a CL15 latency profile at 2133 MHz.
Build and connectors
The module uses a standard 288-pin DIMM edge connector and measures 5.2 inches in length with a thickness of 156.7 mil. RoHS certification confirms compliance with environmental substance restrictions.

Questions about this item
Does the SK hynix HMA42GR7AFR4N-TF come with anything besides the single 16 GB DDR4 ECC Registered DIMM?
The module is sold individually; no brackets, cables or additional sticks are included.
When would I choose this 16 GB 2133 MHz CL15 registered stick over another capacity or speed?
Pick it when your server or workstation requires DDR4-2133 registered ECC memory and you need exactly 16 GB per slot.
What does the 2133 MHz rating mean once the stick is installed in a real machine?
It runs at 2133 MT/s with CL15 latency at 1.20 V, provided the platform supports DDR4-2133 registered ECC DIMMs.
