SK hynix

SK hynix HMA82GS7CJR8N-VK 32GB (2×16GB) DDR4-2666 ECC SODIMM server RAM

SKU CH-9G9Y-PJAGP MPN HMA82GS7CJR8N-VK

A 32 GB DDR4-2666 ECC SODIMM kit with two 16 GB modules for server and compatible laptop upgrades

  • 32 GB total capacity from two 16 GB modules
  • ECC error correction protects data integrity in servers
  • DDR4-2666 speed delivers 21300 MT/s bandwidth
  • Dual-rank 2Rx8 organisation increases memory density
  • 260-pin SODIMM form factor fits compact server slots

Dual-channel 32 GB kit

This 32 GB kit contains two 16 GB DDR4 SODIMM modules rated at PC4-21300 (DDR4-2666). ECC error correction makes it suitable for servers and workstations that require data integrity. It is built for systems that accept 260-pin SO-DIMM memory.

260-pin SO-DIMM form factor

Each module uses the standard 260-pin SO-DIMM edge connector found in many rackmount and blade servers. The dual-rank 2Rx8 organisation fits typical server memory slots without proprietary brackets. Installation follows the usual SODIMM latch mechanism.

ECC operation at DDR4-2666

ECC functionality adds a parity bit per byte so the memory controller can detect and correct single-bit errors during normal workloads. Running at the rated 2666 MT/s bus speed keeps power draw within standard DDR4 limits. No additional cooling is required beyond normal chassis airflow.

Questions about this item

Does the DDR4-2666 interface cap at PC4-21300 bandwidth in practice?

Yes, the DDR4-2666 modules run at PC4-21300, which is the standard peak transfer rate for this speed grade.

What physical slot and pin count do these 260-pin SO-DIMM modules need?

They require a standard DDR4 SO-DIMM slot with 260 pins; the 2Rx8 layout fits any compatible laptop or server socket.

How are the two 16 GB sticks installed, and what step is often missed?

Insert both modules firmly until the side clips click; the step often missed is seating the second stick fully so both channels are active.
