32GB DDR4 ECC Registered RDIMM for Servers

This 32GB DDR4 3200 CL22 module is built for workstations and servers that require ECC registered memory. It operates at 1.2V with a 2Rx4 rank configuration on a 288-pin form factor. The module is designed as a direct replacement for specific QNAP part numbers and meets JEDEC standards.

Verify Platform Supports ECC Registered DDR4

Before ordering, confirm your motherboard and CPU support DDR4 ECC registered RDIMMs. This memory will not work in standard desktop computers that use unbuffered non-ECC modules. It also cannot be mixed with unbuffered memory in the same system. Check your hardware documentation for qualified vendor lists.

Fits 288-Pin DDR4 Slots Requiring Registered ECC

The module installs into standard 288-pin DDR4 DIMM slots that accept registered ECC memory. It requires a compatible server or workstation chipset and BIOS that can initialize registered modules. Using matched capacity and speed across all populated channels helps maintain stability. No heat spreader is included, so ensure adequate airflow in the chassis.

Questions about this item

Does the 288-pin DDR4 3200 RDIMM come alone or with extra parts?

The module ships as a single 32 GB stick. No cables, brackets or additional components are included.

Should I pick the 2Rx4 CL22 1.2 V version or a different capacity?

This is the only capacity offered: 32 GB at DDR4 3200 with CL22 latency and 1.2 V operation.

What does the PC4-25600 rating mean once the RDIMM is installed in a server?

It indicates a peak transfer rate of 25 600 MB/s at 3200 MT/s, provided the platform supports registered ECC memory.
