32GB DDR4 ECC Registered module

This 32GB DDR4 server memory module operates at 3200 MT/s with CL22 latency and 1.20V voltage. It uses a 288-pin DIMM form factor and features registered ECC with a 2Rx8 rank configuration. The module is built for motherboards, servers and workstations that require registered ECC memory.

Sustained throughput with registered ECC

The registered buffer reduces electrical load on the memory controller during continuous operation, helping maintain signal integrity under heavy multi-threaded workloads. ECC detection and correction protects data integrity over long compute sessions without the overhead of parity schemes that lack correction. Dual-rank organisation allows the controller to interleave accesses across ranks, sustaining bandwidth when all channels are populated.

Install in registered ECC slots only

The module fits 288-pin DDR4 DIMM slots that support registered ECC memory; it will not function in consumer platforms that accept only unbuffered non-ECC modules. Mixing registered and unbuffered DIMMs on the same channel prevents the system from posting. Verify that the platform firmware enables ECC and that the memory controller supports the 2Rx8 density before installation.

Questions about this item

Does the 1.20 V DDR4 3200 module run noticeably hotter than lower-speed sticks under continuous load?

It operates at the standard 1.20 V for DDR4, so heat output is comparable to other DDR4 3200 registered DIMMs; adequate chassis airflow keeps temperatures normal.

Will my motherboard need 288-pin DDR4 slots with registered ECC support to use this 32 GB stick?

Yes, the module requires a 288-pin DDR4 slot and a platform that accepts registered ECC memory; consumer boards without that support will not work.

Can this 3200 MT/s CL22 2Rx8 DIMM run in a system that also has slower DDR4 registered ECC modules installed?

The memory controller will clock all modules down to the lowest common speed and latency, so the stick will operate at the slower modules' rated timings.
