OWC 8GB DDR3 ECC UDIMM for ASUSTOR NAS

This OWC module is an 8 GB DDR3 ECC unbuffered UDIMM built to the PC3-12800 1600 MHz CL11 JEDEC standard. It operates at 1.5 V and uses a 240-pin 2Rx8 layout without a heat spreader. The part is validated for ASUSTOR AS7009RDX and AS7012RDX systems as a direct replacement for AS7R-RAM8GEC.

Ideal for owners expanding supported ASUSTOR NAS

Buyers who need to increase memory in an ASUSTOR AS7009RDX or AS7012RDX will find this module matches the required specification. Systems that demand registered DIMMs, a different pin count, non-ECC memory or a voltage other than 1.5 V cannot use this module.

Deciding spec: 240-pin DDR3 ECC unbuffered at 1.5 V

The single detail that determines fit is the 240-pin DDR3 ECC unbuffered design running at 1.5 V with CL11 timing. If the target chassis requires registered memory, a different voltage or another DDR generation this module will not install or function.

Highlights

  • ECC protection guards data integrity in ASUSTOR NAS
  • DDR3 1600 speed matches system bus for stable throughput
  • Single 8 GB module adds capacity without pairing
  • JEDEC-standard 1.5 V unbuffered design ensures warranty-safe upgrade

Questions about this item

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

Power off the NAS, open the chassis, align the notch on the 240-pin module with the slot key, press firmly until both retention clips click, then verify the system recognises the full 8GB at 1600 MHz CL11 on boot.

What maintenance or replacement will the 8GB DDR3 1600 module need over its service life?

The unbuffered ECC UDIMM has no moving parts or heat spreader; it requires no scheduled maintenance and is covered by a limited lifetime warranty, so replacement is only needed if a memory error appears.

What limit appears first when the 1.5V CL11 kit runs sustained workloads on the AS7012RDX?

The module is rated for DDR3 1600 at CL11 1.5V; under continuous load the first ceiling you reach is the JEDEC‑specified speed and latency envelope, not thermal throttling.
