Capacity 32GB (2 x 16GB)

  • 32 GB dual-channel kit expands NAS memory capacity
  • ECC DDR4 2666 CL19 safeguards data integrity in critical workloads
  • 2 V low-voltage modules reduce power draw and heat
  • JEDEC and RoHS compliant for warranty-safe upgrades

Targeted NAS Memory Upgrade

This 32GB kit contains two 16GB DDR4 2666 ECC SODIMM modules built for ASUSTOR AS6504RD, AS6504RS, AS6508T, AS6510T and AS6512RD systems. It suits administrators who need error-correcting memory to protect data integrity in network-attached storage or micro-server roles. Buyers requiring higher frequencies or non-ECC modules for consumer laptops should look elsewhere.

Thermals and Power Profile

The modules operate at a standard 1.2V without heat spreaders, drawing minimal power inside the tight chassis of compatible NAS units. Passive cooling from system airflow is sufficient for continuous 24/7 operation at the rated 2666 speed. No active cooling or additional voltage headroom is required for normal workloads.

Compliance and Compatibility Benefits

JEDEC and RoHS compliance ensures a warranty-safe upgrade that meets OEM specifications for the listed ASUSTOR models. Backward compatibility with 2400 and 2133 speeds allows installation in mixed-speed configurations without manual tuning. The unbuffered 2Rx8 organisation plugs directly into the 260-pin slots for immediate recognition.

Questions about this item

How do I install the 260-pin DDR4 SODIMM modules in my ASUSTOR AS6508T, and what step is often missed?

Power off the NAS, remove the chassis cover, insert each module at a 30-degree angle into the slot until the gold contacts disappear, then press down firmly until both side clips click — the click is the step people skip.

What maintenance or replacement will the ECC unbuffered SODIMM kit need over time?

No scheduled maintenance is required; the modules have no heat spreaders or moving parts, so replacement only occurs if a module fails, which is covered by OWC's limited lifetime advanced-replacement program.

What limit appears first when the AS6512RD runs sustained workloads with this CL19 2666 MHz kit?

The memory controller caps bandwidth at the JEDEC 2666 MT/s rating, so throughput plateaus there before thermal throttling becomes a factor.
