OWC 4GB DDR3 1600 ECC UDIMM 2Rx8 CL11 1.5V 240-pin for ASUSTOR AS7009RDX AS7012RDX

SKU CH-9T54-SXQB1

4GB DDR3 1600 ECC UDIMM module for ASUSTOR AS7009RDX and AS7012RDX systems

  • Capacity4GB
  • Type240-Pin DDR3 ECC UDIMM
  • SpeedDDR3 1600 (PC3 12800)
  • CAS LatencyCL11

  • ECCYes

Capacity 4GB

  • ECC protection prevents data errors in critical workloads
  • 1600 MHz DDR3 speed matches system specifications
  • 5 V operation keeps power draw low
  • 240-pin UDIMM fits ASUSTOR AS7009RDX and AS7012RDX
  • JEDEC compliant module ensures warranty-safe upgrade

ASUSTOR NAS memory upgrade

This 4 GB DDR3 ECC UDIMM is built for the ASUSTOR AS7009RDX and AS7012RDX storage appliances. It installs as a single module to expand system memory for heavier workloads. Buyers needing larger capacities per slot or non-ECC memory should look elsewhere.

Thermals noise and power

The module runs at 1.5 V with standard JEDEC DDR3 1600 timing and no heat spreader. Passive cooling relies on the NAS chassis airflow, so acoustics and power draw stay at stock levels. No active cooling or extra power connectors are involved.

Build quality and connectors

A 240-pin unbuffered DIMM with 2Rx8 organisation fits the native memory slots on the compatible ASUSTOR units. JEDEC and RoHS compliance ensures a warranty-safe upgrade path. The stick lacks RGB lighting or tall heatsinks that could block adjacent slots.

Questions about this item

How do I install the 240-pin DDR3 ECC UDIMM into my ASUSTOR AS7009RDX, and what step is most often missed?

Power off the NAS and unplug it, open the chassis, align the notch on the 240-pin module with the slot key, press firmly until both retention clips click, then reassemble; the step most often missed is fully seating the module so both clips engage.

What maintenance or replacement will this 4GB DDR3 1600 CL11 module need over time?

No scheduled maintenance is required; the module has no heat spreader and runs at 1.5V, so keep the NAS vents clear of dust to maintain airflow, and replace the DIMM only if memory errors appear or capacity needs increase.

What limit appears first when this ECC UDIMM runs sustained workloads on the AS7012RDX?

The 4GB capacity is the first bottleneck; with only one 2Rx8 rank installed, heavy multitasking or large file caches will exhaust available memory before the DDR3 1600 PC3-12800 bandwidth or CL11 latency becomes a constraint.
