8GB DDR4 ECC UDIMM for QNAP NAS

This 8 GB DDR4 ECC unbuffered DIMM runs at 2666 MHz with CL19 latency and 1.20 V operation. It is built for QNAP NAS devices that accept 288-pin UDIMM modules and require error-correcting memory for data integrity. The 2Rx8 organisation uses major OEM chips from Samsung, Micron or Hynix.

Thermals and power in normal use

Operating at the standard 1.20 V for DDR4, the module draws minimal power and generates low heat without a heat spreader. Passive airflow inside a typical NAS chassis is sufficient to keep temperatures in check during continuous operation. No active cooling or extra voltage headroom is needed for stock-speed workloads.

What the bundled specs change

ECC support detects and corrects single-bit errors, protecting stored data from silent corruption in always-on NAS environments. The unbuffered design keeps latency low for the memory controller while the 2Rx8 layout fits the density limits of compatible QNAP models. No additional software or drivers are required beyond the NAS firmware.

Questions sur cet article

How do I install this DDR4 ECC UDIMM in my QNAP NAS and what step is often missed?

Align the notch on the 288-pin module with the slot key, press firmly until both retention clips click, then verify the system reports 8 GB at 2666 MT/s in the NAS firmware — the step most often missed is reseating if the POST does not show the new capacity.

What maintenance or replacement will this 2Rx8 module need over time?

No scheduled maintenance is required; the module has no heat spreader and runs at 1.20 V, so only replace it if memory diagnostics report uncorrectable ECC errors or if you expand capacity beyond the current 8 GB.

What limit appears first when this CL19 kit runs sustained workloads?

The CAS latency of 19 cycles at 2666 MT/s sets the throughput ceiling; under continuous load the memory controller will hit that timing boundary before voltage or thermal limits become a factor.
