SK hynix HMA84GR7MFR4N-UH DDR4 32GB 2400MHz ECC Registered CL17 1.2V 288-pin

SKU CH-JNPD-X141N

32GB DDR4 server module with ECC, registered design and CL17 timing at 2400MHz

  • 32 GB capacity supports heavy server workloads
  • ECC registered design protects data integrity in critical systems
  • 2400 MHz DDR4 speed delivers reliable bandwidth for enterprise apps
  • CL17 latency at 1.2 V balances responsiveness with power efficiency
  • 288-pin dual-rank module fits standard server DIMM slots

32GB DDR4 ECC Registered module

This 32GB DDR4-2400 module is built for servers and workstations that require error-correcting registered memory. It operates at 2400MHz with a CAS latency of 17 and a low 1.2V voltage. The dual-rank x4 organisation provides high density for multi-socket platforms.

288-pin installation and compatibility

The module uses the standard 288-pin DDR4 form factor and inserts into keyed DIMM slots. Registered buffering adds electrical load, so the memory controller must support registered DIMMs; consumer desktop boards without this support will not post. ECC functionality also requires a compatible platform to activate error correction.

Sustained load behaviour in server duty

Under continuous operation the registered buffer helps maintain signal integrity across heavily populated memory channels. The 1.2V rating keeps power draw modest during long compute runs, while ECC detects and corrects single-bit errors that accumulate over time. This combination supports stable throughput for virtualisation and database workloads.

Questions about this item

How can I verify the module is running at 2400MHz with CL17 after installation?

Check the memory speed and timings in your server BIOS or a tool like CPU-Z; they should report 2400MHz and CAS latency 17 when the module is seated correctly.

What comes with the HMA84GR7MFR4N-UH module and do I need extra parts?

The box contains the single 32GB DDR4 288-pin ECC registered DIMM; no cables, brackets or additional components are required for installation.

Which capacity and rank option should I pick for a dual-rank x4 configuration?

This part is a 32GB dual-rank x4 module; choose it when your server requires that specific density and organisation.
