ECC Registered DDR4 for Servers

This 16GB DDR4 module runs at 2400MHz with CL17 latency and 1.2V operation. It uses a 288-pin RDIMM form factor with 2Rx8 organisation and ECC registration. The part matches Hynix HMA82GR7AFR8N-UH and HMA82GR7MFR8N-UH specifications exactly. No heat spreader is fitted.

Suits ECC Registered Platforms Only

This memory fits servers, workstations and NAS systems that require registered ECC DDR4. It will not work in standard desktop computers that use unbuffered non-ECC modules. Mixing with unbuffered memory is not supported. Buyers needing consumer desktop RAM should look elsewhere.

Registered ECC Is the Deciding Factor

The module is a registered ECC RDIMM, not an unbuffered DIMM. Your system must explicitly support registered ECC DDR4 for this part to function. If the platform only accepts unbuffered memory, this module will not be compatible. Verify the requirement before ordering.

Questions about this item

What server motherboard slot does this 288-pin DDR4 RDIMM require?

The module fits a standard 288-pin DDR4 DIMM socket on a server or workstation board that supports ECC registered memory.

Can I keep my existing unbuffered DDR4 modules and add this ECC registered stick?

No, registered and unbuffered DDR4 cannot be mixed; the system must use only registered ECC modules.

How do I confirm the RAM is running at 2400 MHz CL17 after installation?

Check the memory speed and latency in the BIOS or with a tool such as CPU-Z; it should report DDR4-2400 and CL17.
