OWC 64GB (2x32GB) DDR4 2666 ECC SODIMM Kit for ASUSTOR 6504 6508 6510 6512

SKU CH-DY94-QCYSC

Dual 32 GB DDR4 2666 ECC SODIMM kit adds 64 GB to compatible ASUSTOR NAS models

  • Capacity64GB (2 x 32GB)
  • Type260-Pin DDR4 ECC SODIMM
  • SpeedDDR4 2666 (PC4 21300)
  • CAS LatencyCL19
  • Voltage1.2V
  • ECCYes

Capacity 64GB (2 x 32GB)

  • ECC protection prevents data errors in critical NAS workloads
  • 64GB dual-channel kit expands memory capacity for demanding applications
  • 2666MHz DDR4 speed with CL19 latency delivers responsive system performance
  • 2V low-voltage operation reduces power consumption and heat output
  • Compatible with ASUSTOR 6504 6508 6510 6512 series for guaranteed integration

OWC 64GB DDR4 ECC SODIMM kit

This OWC kit supplies 64GB of DDR4 2666 ECC memory in two 32GB modules. It uses 260-pin SODIMM form factor, runs at 1.2V with CL19 latency, and is validated for specific ASUSTOR NAS models including the 6504, 6508, 6510 and 6512 series.

Suited for ASUSTOR NAS owners needing maximum ECC

Builders expanding an ASUSTOR 6504, 6508, 6510 or 6512 unit to 64GB will find this kit a direct fit. It is not for systems that require registered DIMMs, non-ECC memory, or 288-pin desktop modules, nor for platforms limited to lower maximum capacities.

64GB total across two 32GB modules

The kit delivers 64GB of ECC-protected DDR4 2666 bandwidth, with backward compatibility to 2400 and 2133 speeds. It fills both SODIMM slots on compatible ASUSTOR units, so further expansion would require replacing modules rather than adding to them.

Questions about this item

Which ASUSTOR NAS models must I already own for this 64GB DDR4 2666 ECC SODIMM kit to work?

This kit is validated for the ASUSTOR AS6504RD, AS6504RS, AS6508T, AS6510T and AS6512RD.

Will the 2666MHz modules run correctly if my NAS currently uses 2400MHz or 2133MHz memory?

Yes, the modules are backwards compatible with 2400MHz and 2133MHz and will operate at the highest speed the system supports.

How can I confirm the 64GB ECC kit is detected and running at CL19 after installation?

Check the NAS system information or BIOS; it should show 64GB total capacity, DDR4 2666 speed, ECC enabled and CAS latency 19.
