32GB DDR3 ECC kit for Synology DS3612xs

This 32GB kit contains four 8GB DDR3-1600 ECC unregistered DIMMs built for the Synology DiskStation DS3612xs. Each module runs at CL11 with 1.5V voltage and a 2Rx8 organisation. The 240-pin form factor matches the four memory slots in that specific NAS chassis.

ECC and dual-channel operation

Error-correcting code protects stored data against single-bit errors, which is critical for a file server that runs continuously. The four identical modules populate every slot, enabling dual-channel bandwidth across the memory controller. Computer Memory Solutions guarantees compatibility with the DS3612xs and backs the kit with a limited lifetime warranty.

Verify slot count and maximum capacity

The DS3612xs accepts a maximum of 32GB across its four DIMM slots, so this kit fills the platform completely. Confirm that your unit is the DS3612xs model and not a different DiskStation variant, because other models use different memory types or lower limits. No heat spreader is guaranteed; the modules ship as standard unbuffered DIMMs.

Questions about this item

Will the ECC DDR3-1600 modules need replacement if a single stick fails?

The kit contains four 8 GB sticks; a failed module can be swapped individually without replacing the full 32 GB set.

What limits sustained throughput on the DS3612xs with this memory installed?

The DDR3-1600 CL11 specification caps bandwidth at the rated PC3-12800 speed under continuous load.

How much heat and power do the four 1.5 V unbuffered DIMMs produce in all-day operation?

Each module runs at 1.5 V with standard DDR3 power draw; no extra cooling is required beyond the system's normal airflow.
