ECC Registered DDR4 for QNAP ES Series

This 32 GB DDR4 3200 module is built for QNAP ES1686dc and ES2486dc servers. It delivers registered ECC reliability for workloads that demand data integrity. The single DIMM installs directly into compatible 288-pin slots without extra configuration. It will not work in standard desktop or unbuffered platforms.

32 GB CL22 capacity and headroom

One module provides 32 GB at CL22 latency and 1.2 V operation. The 2Rx4 organisation suits multi-channel server boards that populate all slots. Systems needing more than 32 GB per channel will require additional identical modules. Maximum total memory depends on the host chassis and is not defined by this part.

JEDEC DDR4 build and registered connectors

The stick follows JEDEC DDR4 specifications with a registered 288-pin interface and no heat spreader. Registered signalling reduces electrical load on the memory controller in dense configurations. ECC circuitry corrects single-bit errors during operation. Mixing with unbuffered DIMMs is not supported and will prevent boot.

Questions sur cet article

Will this 32GB DDR4 3200 CL22 2Rx4 ECC Registered RDIMM work alongside the original QNAP modules in my ES1686dc?

Yes, this module replaces QNAP part numbers RAM-32GDR4ECK0-RD-3200, RAM-32GDR4ECK1-RD-3200 and RAM-32GDR4ECT0-RD-3200 and matches the required DDR4 3200 CL22 1.2V registered specification for the ES1686dc and ES2486dc.

How can I confirm the 32GB DDR4 3200 CL22 2Rx4 ECC Registered RDIMM is detected correctly after installing it in my ES2486dc?

Power on the NAS and open the QTS Control Panel, then go to System > Hardware to verify the total memory shows the expected increase and the module speed reads DDR4 3200.

What is included with the 32GB DDR4 3200 CL22 2Rx4 288-pin ECC Registered RDIMM and what else might I need?

The box contains a single 32GB DDR4 3200 PC4-25600 CL22 2Rx4 288-pin 1.2V ECC Registered DIMM; no additional parts are required for installation in a compatible QNAP ES1686dc or ES2486dc.
