OWC 8GB DDR4 2666 ECC Registered RDIMM server RAM

SKU CH-Y0Q7-F9E0K

An 8 GB DDR4 2666 ECC registered RDIMM for Synology FS3400, FS3410 and FS3600 NAS systems

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

Capacity 8GB

Rank 1Rx4

  • ECC registered design protects data integrity in servers
  • DDR4 2666 MHz CL19 speed matches system timing
  • 2 V operation reduces power draw per module
  • Single 8 GB 1Rx4 rank fits one 288-pin slot
  • Backward compatible with 2133 MHz and 2400 MHz systems

Target systems

This 8GB DDR4 2666 ECC Registered RDIMM is built for servers, workstations and NAS units that require registered error-correcting memory. It replaces Synology D4RD-2666-8G and D4ER01-8G modules in FlashStation FS3400, FS3410 and FS3600 systems. The module runs at PC4-21300 speed with CL19 latency at 1.2V.

Compatibility guidance

It suits administrators upgrading compatible rackmount or tower servers that accept 288-pin registered DIMMs. It will not work in standard desktop PCs, laptops or consumer motherboards that only support unbuffered memory, and it cannot be mixed with load-reduced or unbuffered ECC modules in the same platform.

Deciding specification

The registered ECC design with 1Rx4 organisation is the single factor that determines fit; only systems explicitly qualified for registered DDR4 ECC RDIMMs can use this module. Backward compatibility with 2133MHz and 2400MHz buses allows deployment in older slots without changing the memory type.

I korthet

  • ECC registered design protects data integrity in servers
  • DDR4 2666 MHz CL19 speed matches system timing
  • 2 V operation reduces power draw per module
  • Single 8 GB 1Rx4 rank fits one 288-pin slot
  • Backward compatible with 2133 MHz and 2400 MHz systems

Frågor om den här produkten

Will this 2666 MHz DDR4 module run at its rated speed in a Synology FS3600?

The FS3600 memory controller operates at 2666 MHz, so the module will run at its full PC4-21300 data rate without downclocking.

Does the registered ECC design limit which DIMM slots I can populate on a Synology FS3410?

Registered ECC modules must be used in registered-compatible slots; the FS3410 only accepts registered DIMMs, so any populated slot will work.

Will the 288-pin RDIMM fit inside the Synology FS3400 chassis without a low-profile bracket?

The module uses the standard 288-pin RDIMM form factor with no heat spreader, matching the FS3400's vertical DIMM sockets exactly.
