Synology RS2421+ DDR4 ECC kit
This 32 GB kit contains two 16 GB DDR4 2666 ECC unbuffered UDIMMs built for the Synology RackStation RS2421+ and RS2421RP+. Each module runs at 1.2 V with CL19 latency and uses a 288-pin layout. The memory is validated for NAS workloads that demand error correction.
Sustained-load behaviour with ECC
Under continuous operation the ECC logic detects and corrects single-bit errors, preventing silent data corruption during long file transfers or backup jobs. Unbuffered topology keeps latency low while the 2Rx8 organisation maintains stable throughput across both DIMMs. Modules are stress-tested at rated speed before shipping.
Pre-installation checks for RS2421+
Confirm the NAS has two free UDIMM slots and that the firmware supports 32 GB total capacity. Verify the chassis can accept standard-height 288-pin sticks without a heat spreader. Ensure the system is powered down and disconnected before opening the memory compartment.

商品問答
How much power will the 1.20 V DDR4 2666 kit draw when the NAS runs continuously?
Each module operates at 1.20 V, the standard DDR4 voltage, so total power draw stays within the platform's normal memory budget for 32 GB.
What must the RS2421+ already have for this 288-pin ECC UDIMM kit to work?
The Synology RS2421+ needs free DDR4 UDIMM slots and a BIOS that accepts ECC unbuffered memory; the kit is validated for that platform.
Will the CL19 2666 MT/s modules run stably alongside any original sticks I keep in the RS2421+?
The kit is tested for the RS2421+/RS2421RP+; matching speed, voltage and ECC type lets the system train all populated slots together.
