Hynix 8 GB DDR4-2400 ECC REG DIMM

This registered ECC module adds 8 GB of DDR4 memory to compatible servers and workstations. It runs at 2400 MHz with a CAS latency of 17. The 288-pin DIMM is built for systems that require error correction and registered signalling.

Registered ECC DDR4 practical limits

Registered ECC DDR4 modules must be used with motherboards and CPUs that support both ECC and registered buffering. Mixing registered and unbuffered DIMMs will prevent the system from posting. Maximum capacity and speed depend on the platform's memory controller and qualified vendor list.

Check platform support before ordering

Verify that your motherboard and processor explicitly support DDR4 registered ECC memory. Confirm the number of available 288-pin slots and the maximum supported speed per slot. Ensure the BIOS is updated to a version that recognises this module type.
