OWC 8GB DDR4 3200 PC4-25600 CL22 1Rx8 288-pin 1.2V ECC Registered RDIMM memory upgrade

SKU CH-NAVN-70V82

ECC registered DDR4 module adds 8 GB at 3200 MT/s for compatible QNAP servers

  • Capacity8GB
  • Type288-Pin DDR4 ECC RDIMM
  • SpeedDDR4 3200 (PC4 25600)
  • CAS LatencyCL22
  • Voltage1.2V
  • ECCYes

Capacity 8GB

  • ECC protection prevents data corruption in server workloads
  • Registered design stabilises signals for QNAP ES1686dc and ES2486dc
  • 3200 MT/s DDR4 speed matches PC4-25600 system requirements
  • Low 1.2 V operation reduces power draw and heat
  • Single 8 GB module with CL22 latency for straightforward capacity expansion

Compatible QNAP NAS models

This 8GB DDR4 ECC Registered DIMM is built for QNAP ES1686dc and ES2486dc systems. It targets administrators upgrading memory in those specific rackmount NAS units. The module will not work in standard desktop computers or consumer motherboards. It also cannot be mixed with unbuffered memory modules.

Registered ECC DDR4 specification

The stick runs at DDR4 3200 with a PC4-25600 data rate and CL22 latency at 1.2V. It uses a 1Rx8 organisation across 288 pins and includes a register to buffer address and command signals. ECC capability detects and corrects single-bit errors for data integrity in server workloads.

Server memory installation notes

Each module is a single 8GB rank without a heat spreader, fitting standard 288-pin DDR4 slots in the supported QNAP models. OWC recommends populating all channels with identical capacity, speed and manufacturer modules for optimal performance. The registered design requires a platform that supports registered DIMMs.

Questions sur cet article

How does the 3200 MT/s speed translate once this module is installed in a QNAP ES1686dc or ES2486dc?

The module runs at its rated DDR4 3200 speed when the system memory controller supports that frequency; otherwise it will down-clock to the highest speed the platform allows.

What does the 288-pin registered DDR4 interface mean for compatibility with these NAS units?

The 288-pin RDIMM form factor and registered ECC design match the memory slots in the ES1686dc and ES2486dc, and it cannot be used in standard desktop boards that expect unbuffered DIMMs.

What physical clearance does the 1Rx8 module need inside the chassis?

It is a standard-height 288-pin DIMM without a heat spreader, so it fits the regular memory slots in the QNAP ES1686dc and ES2486dc without extra clearance.
