Green 288-pin DDR4 DIMM module with black chips

Qnap

QNAP 4GB DDR4-2666 ECC DIMM RAM-4GDR4ECP0-UD-2666

SKU CH-NA1Y-WK0B5

Adds 4 GB of DDR4 ECC memory at 2666 MHz to compatible QNAP NAS servers

  • ECC protection prevents data corruption in critical NAS workloads
  • 2666 MHz DDR4 speed supports responsive enterprise storage performance
  • 20 V low voltage reduces power draw and heat output
  • Unbuffered 288-pin DIMM installs directly into compatible QNAP servers
  • Validated for TS-983XU enterprise NAS ensuring reliable compatibility

QNAP 4GB DDR4-2666 ECC DIMM

This 4GB DDR4-2666 ECC DIMM provides error-correcting memory for compatible QNAP NAS servers. It operates at 2666 MHz with a low 1.20 V voltage and uses an unbuffered 288-pin design. The module weighs approximately 4.23 oz and is built for the TS-983XU Enterprise NAS Server.

DDR4-2666 standard limits

The DDR4-2666 standard caps the data rate at 2666 MHz and the PC4 rating at PC4-21333. ECC functionality works only when the host platform supports error-correcting code memory. Unbuffered signal processing means the module connects directly to the memory controller without a register. The 1.20 V operating voltage is fixed for this standard.

Check NAS compatibility first

Verify that your QNAP NAS model accepts 288-pin DDR4 DIMMs with ECC and unbuffered operation. The manufacturer confirms compatibility with the TS-983XU Enterprise NAS Server. Other models may require different form factors, voltages, or non-ECC memory. Consult your system documentation before ordering.

Questions about this item

Should I choose the 4 GB DDR4-2666 ECC DIMM or a different capacity for my NAS?

This module provides 4 GB of DDR4 ECC memory at 2666 MHz; select it when your NAS requires a single 4 GB unbuffered DIMM for error-correcting operation.

What does the 2666 MHz rating deliver once installed in a NAS?

The 2666 MHz speed enables a PC4-21333 data rate, giving the NAS server high-throughput memory bandwidth for file services and virtualization workloads.

How does the 288-pin DDR4 interface limit performance in practice?

The 288-pin DDR4 DIMM runs at 1.20 V with unbuffered signalling, capping the module at the DDR4-2666 standard supported by the TS-983XU NAS.
