Green 288-pin DDR4 DIMM with black chips, 16 GB registered ECC

SK hynix

SK hynix HMA42GR7MFR4N-TF DDR4-2133 16GB ECC Registered CL13 server RAM

SKU CH-CFRQ-QF1PA

16 GB DDR4-2133 ECC registered DIMM with CL13 latency for server workloads

  • Capacity16GB
  • Type288-Pin DDR4 SDRAM
  • SpeedDDR4 2133 (PC4 17000)
  • CAS LatencyCL13
  • ECC protection prevents data corruption in critical workloads
  • Registered buffering reduces electrical load for stable server operation
  • 16 GB capacity on a single module simplifies memory upgrades
  • DDR4-2133 speed with CL13 latency delivers responsive performance
  • 2 V operation lowers power consumption in dense deployments

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.

Domande su questo articolo

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.
