OWC 8GB DDR4 2666MHz ECC SODIMM 1Rx8 DS923+ memory upgrade

SKU CH-PBES-ZT525

8GB DDR4 2666MHz ECC SODIMM upgrades Synology DS923+ NAS with 1Rx8 unbuffered memory at 1.2V CL19

  • Capacity8GB
  • Type260-Pin DDR4 ECC SODIMM
  • SpeedDDR4 2666 (PC4 21300)
  • CAS LatencyCL19
  • Voltage1.2V
  • ECCYes

Capacity 8GB

Struck-through versions exist but are not stocked here.

  • ECC protection guards data integrity in your NAS
  • 2666 MHz DDR4 speed matches DS923+ specs for stable operation
  • 8 GB capacity expands memory for heavier workloads
  • 2 V low voltage reduces heat and power draw
  • Backward compatible with 2400 MHz and 2133 MHz systems

8GB DDR4 ECC SODIMM for Synology DS923+

This single 8GB module upgrades the Synology DiskStation DS923+ with DDR4 2666MHz ECC memory. It uses a 260-pin SODIMM form factor running at 1.2V with CL19 latency. The unbuffered 1Rx8 design meets JEDEC standards for reliable NAS operation.

Ideal for DS923+ owners needing ECC reliability

This upgrade suits administrators expanding memory in a Synology DS923+ where error-correcting code is required for data integrity. Buyers with non-ECC platforms or systems requiring registered DIMMs should look elsewhere.

1Rx8 unbuffered ECC SODIMM at 2666MHz

The 1Rx8 unbuffered ECC configuration at DDR4 2666MHz determines compatibility with the DS923+ memory controller. Verify your NAS accepts unbuffered ECC SODIMMs before purchase.

Questions about this item

Does the OWC 8GB DDR4 2666MHz ECC SODIMM arrive as a single stick or a kit, and are any tools needed for the DS923+ slot?

The upgrade consists of one 8GB 260-pin DDR4 ECC SODIMM. No extra modules, cables or tools are required; the stick inserts directly into the Synology DS923+ memory slot.

Should I choose the 1Rx8 2666MHz CL19 version or look for a different rank or speed for the DS923+?

This module matches the DS923+ specification: DDR4 2666MHz PC4-21300 CL19 1Rx8 ECC unbuffered at 1.2V. It also runs at 2400MHz and 2133MHz if the system downclocks.

What does the 2666MHz PC4-21300 rating actually deliver inside a DS923+ NAS?

The module operates at 2666MHz with CL19 latency, providing 8GB of ECC-protected capacity. The DS923+ memory controller sets the final throughput, and the stick will run at 2400MHz or 2133MHz if the system requires a lower speed.
