OWC 32GB (4x8GB) DDR3 1600 CL11 2Rx8 240-pin 1.5V UDIMM Kit AS7009RD AS7012RD

SKU CH-0C61-8C9SM

A 32 GB DDR3 kit of four 8 GB modules running at 1600 MHz CL11 for ASUSTOR AS7009RD and AS7012RD systems

  • Capacity32GB (4 x 8GB)
  • Type240-Pin DDR3 Non-ECC UDIMM
  • SpeedDDR3 1600 (PC3 12800)
  • CAS LatencyCL11
  • Voltage1.5V
  • ECCNo

Capacity 32GB (4 x 8GB)

  • 32 GB total capacity from four 8 GB modules
  • DDR3 1600 speed with CL11 latency for responsive multitasking
  • 5 V JEDEC-standard voltage ensures broad desktop compatibility
  • 240-pin unbuffered non-ECC UDIMM fits ASUSTOR AS7009RD and AS7012RD
  • 100 % JEDEC and RoHS compliant for a warranty-safe upgrade

Targeted upgrade kit

This 32GB kit contains four 8GB DDR3 1600 CL11 unbuffered UDIMMs built for ASUSTOR AS7009RD and AS7012RD systems. It runs at 1.5V with 2Rx8 organisation and 240-pin form factor. The modules carry no heat spreader and are non-ECC. Buyers needing ECC protection or registered DIMMs cannot use this kit.

Sustained workload behaviour

JEDEC-standard PC3-12800 timing keeps latency stable at CL11 during long file transfers or multi-user database jobs. Four ranks per channel let the memory controller interleave requests without throttling. The 1.5V operating point avoids voltage droop that can appear on lower-voltage modules under continuous load. Systems requiring higher frequencies than 1600MHz will not benefit from this kit.

Thermals noise and power

Bare green PCBs rely on chassis airflow rather than spreaders so case ventilation must reach the DIMM slots. At 1.5V each module draws only its rated power with no extra voltage headroom. Silent operation is assured because no active cooling is attached. Builders using compact enclosures with restricted airflow should verify slot clearance before ordering.

Questions about this item

Does the 1.5V DDR3 1600 kit run hot or draw extra power in an ASUSTOR AS7009RD that operates 24/7?

The modules are standard 1.5V JEDEC DDR3 1600 CL11 UDIMMs with no heat spreader, so they operate at stock voltage and thermal levels for continuous NAS use.

What must my ASUSTOR AS7012RD already have to accept this 4×8GB upgrade?

The NAS needs four free 240-pin DDR3 UDIMM slots and a firmware that supports 32GB total capacity with 2Rx8 non-ECC modules.

Will these CL11 1600MHz sticks work alongside the original memory that came in my AS7009RD?

Yes, they are 1.5V non-ECC unbuffered DDR3 1600 CL11 2Rx8 DIMMs, matching the JEDEC spec the AS7009RD expects, so they can run mixed with the factory modules.
