16 GB ECC RDIMM for QNAP NAS

This registered DDR4 module delivers 16 GB of error-correcting memory at 2400 MT/s. It targets administrators upgrading compatible QNAP NAS appliances that require RDIMM technology for data integrity.

CL17 timing and 1.2 V operation

The module runs at CAS latency 17 with a standard 1.2 V supply, matching the power envelope of typical server platforms. No heat spreader is fitted, so airflow in the chassis handles cooling directly.

288-pin registered dual-rank layout

The 2Rx8 organisation uses major OEM DRAM from Samsung, Micron or Hynix. The 288-pin RDIMM form factor fits only motherboards designed for registered ECC memory; it will not work in consumer desktop boards that accept only unbuffered DIMMs.

Questions about this item

Will the 2Rx8 registered DIMM need any firmware updates or chip replacement over its service life?

No firmware updates are required for the memory module itself; the Samsung, Micron or Hynix DRAM chips are soldered and not user-replaceable.

What thermal limit appears first when the module runs continuously at 2400 MT/s?

The 1.20 V DDR4 chips are rated for standard JEDEC operating temperatures, so the system's case airflow — not the DIMM — sets the practical ceiling.

How much extra heat and power does a single 16 GB stick add when the NAS runs 24/7?

At 1.20 V the module draws only a few watts and has no heat spreader, so it adds minimal thermal load to a ventilated chassis.
