Synology DS3612xs DDR3 ECC Upgrade

This 8GB kit contains two 4GB unregistered ECC DIMMs built for the Synology DiskStation DS3612xs. Each module runs at 1600MHz with CL11 timings at 1.5V. The 240-pin DDR3 design fits the four available slots and supports the system maximum of 32GB.

Sustained Load Behaviour

ECC circuitry corrects single-bit errors during continuous operation, reducing silent data corruption on long file transfers or RAID rebuilds. Unbuffered layout keeps latency low at CL11-11-11 while the 2Rx8 organisation maintains bandwidth across dual-channel pairs. Rated 1.5V voltage remains stable under extended workloads.

Build and Connectors

Modules use major-brand chips on standard-height green PCBs without heat spreaders, allowing tight spacing inside the DiskStation chassis. The 240-pin gold-edge connectors seat firmly in the proprietary slots. A matched pair ensures dual-channel interleaving from the first boot. Lifetime repair or exchange warranty covers manufacturing defects.

Questions about this item

How much heat and power does the 1.5V DDR3 kit draw when the DS3612xs runs continuously?

The modules operate at 1.5V with no heat spreader, so they rely on the chassis airflow; power draw is typical for unregistered DDR3 1600 ECC DIMMs under sustained load.

What must the DS3612xs already have installed for this 2x4GB kit to function?

The NAS needs a free 240-pin DDR3 slot and a CPU and chipset that support unregistered ECC memory; the system max is 32GB across four sockets.

Can I mix these CL11 2Rx8 sticks with older DDR3 modules already in the DS3612xs?

Yes, provided the existing memory is also unregistered ECC DDR3 1600; the kit will run in dual-channel mode when paired in matched slots.
