Green DDR4 memory module with gold contacts and black chips

SK hynix

SK hynix DDR4-2666 32GB 2Gx4 ECC Registered CL19 Server Memory

SKU CH-H3YR-CJ1MG

32 GB DDR4 server memory with ECC registered operation at 2666 MHz, CL19 and 1.2 V

  • ECC registered protects data integrity in critical workloads
  • DDR4-2666 delivers 21300 MT/s bandwidth for server throughput
  • Dual-rank 2G x 4 organisation maximises 32 GB capacity per DIMM
  • CL19 at 1.2 V balances latency and power efficiency

32 GB DDR4-2666 ECC Registered DIMM

This 32 GB DDR4 module runs at 2666 MHz with a CL19 latency and operates at 1.2 V. It uses a 288-pin form factor and a 2G x 4 dual-rank organisation. Error-correcting code and registered buffering are both supported. The part is intended for server platforms that require registered ECC memory.

Requires registered ECC memory slots

The module will only function in systems that accept DDR4 registered ECC DIMMs. Consumer desktop boards and laptops that lack registered-buffer support cannot use this memory. Buyers who need unbuffered non-ECC RAM for a standard PC should select a different module.

Questions about this item

What does 2666 MHz mean once the module is installed in a server?

The module transfers data at 2666 million cycles per second, delivering up to PC4-21300 bandwidth when the platform runs the memory at its rated speed.

How does the 288-pin DDR4 interface limit performance in practice?

The 288-pin DDR4 connector caps the module at 2666 MHz and 1.2 V, so the system cannot exceed PC4-21300 throughput regardless of faster CPU support.
