8GB DDR4 2666 ECC UDIMM for Synology RS2423+

This 8GB DDR4 2666MHz ECC unbuffered UDIMM is built for Synology RackStation RS2423+ and RS2423RP+ NAS units. It adds capacity to systems that support ECC memory for data integrity. The single-rank 1Rx8 module runs at 1.2V with CL19 latency. It suits administrators expanding memory in compatible rack-mounted storage servers.

DDR4 2666 standard limits module speed and voltage

The DDR4 2666 (PC4-21300) JEDEC standard fixes the maximum data rate at 2666 MT/s and the operating voltage at 1.2V. Modules rated for 2133MHz or 2400MHz will down-clock to match the slowest installed DIMM. ECC unbuffered UDIMMs cannot be mixed with registered or load-reduced DIMMs in the same channel. The 288-pin form factor fits only DDR4 slots.

Verify NAS model and free DIMM slots before ordering

Confirm the unit is a Synology RS2423+ or RS2423RP+; other models may not accept this part. Check how many memory slots the chassis provides and whether any are already populated. Ensure the system firmware is current so the new module is recognised at the correct speed. The module has no heat spreader, so airflow around the DIMM area must be adequate.

Questions about this item

Should I pick the 8GB module or a larger capacity for my RS2423+?

This listing is for a single 8GB DDR4 2666 ECC UDIMM. If your Synology RS2423+ or RS2423RP+ has empty slots, adding one 8GB stick increases total memory by 8GB.

What does the 2666MHz speed actually deliver inside my NAS?

The module runs at DDR4 2666 (PC4-21300) with CL19 latency at 1.2V. In your RS2423+ it will operate at the system's supported memory frequency, improving multitasking and file-handling responsiveness.

Is the 288-pin DDR4 ECC UDIMM interface compatible with my RackStation?

Yes. The 288-pin DDR4 ECC unbuffered DIMM matches the memory slot specification for Synology RS2423+ and RS2423RP+ units. It is also backward compatible with 2133MHz and 2400MHz operation.
