Green 260-pin DDR4 SO-DIMM module without heat spreader

Kingston Technology Corp.

Kingston Technology Corp. KTH-PN426E/16G 16GB DDR4 2666 ECC SO-DIMM server RAM

SKU CH-1T5X-Z7X25 MPN KTH-PN426E/16G

16 GB DDR4 2666 ECC unbuffered SO-DIMM with CL19 latency for server memory upgrades

  • Total capacity16 GB
  • Rated speedDDR4 2666 (PC4 21300)
  • CAS latencyCL19
  • Rated voltage1.2 V
  • Buffer typeUnbuffered
  • Memory rank2Rx8
  • 16 GB capacity supports larger workloads
  • DDR4 2666 speed delivers high data throughput
  • ECC protection detects and corrects memory errors
  • Unbuffered design reduces latency for faster response
  • 20 V operation lowers power consumption

Server memory for compact systems

This 16 GB DDR4 SO-DIMM targets servers and workstations that use 260-pin slots. ECC unbuffered operation adds single-bit error correction without the latency penalty of registered modules, making it suited for data-integrity workloads in space-constrained chassis.

Capacity and headroom

A single 16 GB module running at 2666 MT/s (PC4-21300) with CL19 timing delivers ample headroom for virtualization hosts, database caches or multi-user application servers. Workloads that exceed 16 GB per slot or require higher frequencies will need additional modules or a faster platform.

Build and daily implications

The module operates at 1.20 V and has no heat spreader, keeping the profile low for tight SO-DIMM spacing. Its 2Rx8 rank organisation works with standard unbuffered ECC controllers, while the 260-pin edge connector ensures direct compatibility with DDR4 SO-DIMM sockets.

Questions about this item

Will this 260-pin DDR4 SO-DIMM run at 2666 MT/s in a server that currently uses slower DDR4 modules?

The module is rated for DDR4 2666 (PC4 21300) and will downclock automatically to match the slowest installed memory, so it works alongside slower DDR4 SO-DIMMs.

How can I confirm the ECC function is active after installing this 16 GB module?

Enter the server BIOS or UEFI and verify that ECC is reported as enabled for the new 2Rx8 DIMM; most server management consoles also show corrected error counters per module.

Does the KTH-PN426E/16G package include a heat spreader or any mounting hardware?

The module has no heat spreader and ships as a single unbuffered 260-pin SO-DIMM; no brackets, screws or thermal pads are included.
