OWC 8GB DDR4 2666MHz ECC UDIMM CL19 1.2V 1Rx8 288-pin FS2500

SKU CH-8C87-2CGJE

Adds 8 GB of DDR4 ECC memory at 2666 MHz CL19 for Synology FlashStation FS2500

  • Capacity8GB
  • Type288-Pin DDR4 ECC UDIMM
  • SpeedDDR4 2666 (PC4 21300)
  • CAS LatencyCL19
  • Voltage1.2V
  • ECCYes

Capacity 8GB

  • ECC protection guards data integrity in your Synology FlashStation FS2500
  • 2666 MHz DDR4 speed accelerates NAS workloads and multitasking
  • Low 1.2 V operation reduces power draw and heat
  • 288-pin UDIMM fits directly into the FS2500 memory slots
  • Backward compatible with 2133 MHz and 2400 MHz systems

Synology FS2500 memory upgrade

This 8 GB DDR4 ECC UDIMM is built specifically for the Synology FlashStation FS2500. It targets administrators who need to expand NAS memory without voiding the original warranty.

8 GB at 2666 MHz with CL19 timing

The module runs at PC4-21300 speed and 1.2 V, using a single-rank 1Rx8 layout. It will down-clock to 2400 MHz or 2133 MHz if the system requires it. Eight gigabytes adds headroom for virtual machines and cached workloads, but heavy multi-tenant databases may still exhaust the capacity.

288-pin unbuffered ECC DIMM

Installation needs a free DDR4 UDIMM slot that accepts ECC unbuffered modules. No heat spreader is fitted, so airflow across the sticks must be maintained by the chassis fans. The JEDEC-standard design keeps the existing warranty intact and frees you from proprietary memory sourcing.

Soalan tentang produk ini

Will this 2666 MHz DDR4 ECC UDIMM run reliably alongside my existing 2133 MHz modules in the Synology FlashStation FS2500?

Yes, the module is backward compatible with 2133 MHz and 2400 MHz speeds, so it will downclock to match the slower DIMMs already installed.

How can I verify the 8 GB stick is operating at CL19 and 1.2 V after installation?

Check the system BIOS or Synology DSM memory information page; it will report the detected speed, CAS latency and voltage for each installed DIMM.

Does the box contain only the single 288-pin DIMM, or are any tools or extra brackets included?

The package includes one 8 GB DDR4 2666 ECC UDIMM module only; no tools, brackets or additional accessories are supplied.
