16GB DDR4-2400 ECC Registered Module

This 16GB DDR4 SDRAM module operates at 2400 MT/s with a CAS latency of 17. It is built for servers and workstations that require error-correcting code and registered signal buffering for stable operation under continuous load. The 288-pin DIMM uses Hynix chips and conforms to the PC4-19200 standard.

Verify DDR4 ECC Registered Compatibility

Confirm that your motherboard supports DDR4 ECC registered DIMMs and accepts 288-pin modules running at 2400 MT/s with CL17 timing. Systems designed for unbuffered non-ECC memory or for other DDR generations will not work with this module. Check the vendor documentation for maximum capacity per slot and populated-channel speed limits before ordering.
