Synology RackStation RS2418+/RS2418RP+ Memory Kit

This 32 GB kit contains four 8 GB DDR4 2400 modules built for Synology RackStation RS2418+ and RS2418RP+ systems. ECC non-registered DIMMs provide error correction for data integrity in storage workloads. The kit fills all four available slots and reaches the platform maximum of 64 GB when combined with an identical set.

Check Slot Count and Module Population

Verify the chassis has four free 288-pin DDR4 slots before ordering because the kit occupies every socket. Confirm the system BIOS or DSM firmware recognises 2Rx8 unregistered ECC modules at 1.2 V. Ensure no mixed-rank or mixed-speed DIMMs remain installed, as mismatched populations can prevent boot or disable ECC.

Sustained Load Behaviour Without Heat Spreaders

Modules run at CL17 17-17-17 timings and 1.2 V continuously during long file transfers or RAID rebuilds. Absence of heat spreaders means case airflow must move enough air across the PCB to keep temperatures in specification. ECC correction handles single-bit errors transparently so data integrity holds steady under multi-hour workloads.

Questions about this item

Does the box contain four 8 GB DDR4 modules or do I need to order extra sticks?

The package includes four 8 GB DDR4 2400 ECC unregistered DIMMs, giving 32 GB total with no additional modules required.

Should I choose the 32 GB kit or a different capacity for my RS2418+?

The Synology RS2418+ and RS2418RP+ support a maximum of 64 GB across four slots, so this 32 GB kit fills half the capacity and leaves two slots free for future expansion.

Will the DDR4 2400 CL17 rating run at full speed once installed in the RackStation?

The modules operate at DDR4 2400 (PC4 19200) with CL17 timing at 1.2 V, matching the specifications supported by the compatible Synology RackStation models.
