SK hynix HMA82GU7CJR8N-VK 16GB 2Rx8 DDR4-2666 ECC UDIMM

SKU CH-K332-05VVT

16 GB DDR4-2666 ECC UDIMM module with 2Rx8 organisation for server stability

  • ECC protection prevents data corruption in servers
  • DDR4-2666 speed delivers 21300 MT/s bandwidth
  • 16 GB capacity in a single UDIMM module
  • Low 1.2 V voltage reduces power draw
  • Standard height fits typical server chassis

16GB DDR4-2666 ECC UDIMM for servers

This 16 GB DDR4-2666 ECC UDIMM module is built for server platforms that require error-correcting memory. It operates at 1.2 V with a standard-height profile and a 2Rx8 rank configuration. The single-module kit suits administrators upgrading or populating compatible DIMM slots.

Verify UDIMM ECC support and DDR4-2666 compatibility

Confirm that your motherboard accepts unbuffered ECC UDIMMs and can run DDR4 at 2666 MT/s. Check the qualified vendor list for 2Rx8 rank modules and ensure the BIOS is current. Systems limited to registered DIMMs or non-ECC memory will not work with this part.

Single module simplifies capacity scaling

The kit contains one 16 GB stick so you can add capacity in precise increments without buying matched pairs. Standard-height construction fits typical server chassis clearance. ECC functionality activates automatically on supported platforms with no extra software required.

Questions about this item

Does the UDIMM arrive as a single 16 GB stick or do I need to buy additional modules?

The kit contains one 16 GB UDIMM so the full capacity is ready to install without purchasing extra modules.

Why does the label show PC4-21300V-E when the module is advertised as DDR4-2666?

PC4-21300V-E is the peak bandwidth designation that corresponds to the 2666 MT/s data rate.

Will the ECC feature work on a standard desktop motherboard or is a server platform required?

ECC functions only when the CPU and motherboard both support error-correcting code memory; many consumer boards ignore the feature.
