Capacity and role

This 32 GB DDR4 registered ECC module targets servers and workstations that require error-correcting memory for data integrity. It suits administrators expanding capacity in compatible Dell PowerEdge, HP ProLiant, Intel and Supermicro platforms listed by the supplier.

Build fit and constraints

The stick uses a 288-pin RDIMM form factor at 1.2 V with CL19 latency and a dual-rank 2Rx4 organisation. It cannot be mixed with unbuffered or load-reduced DIMMs in the same system, so the entire chassis must use registered modules of the same specification.

Bundled items and software

No accessories, cables or software licences are included with the module. The only change comes from the additional 32 GB of registered ECC capacity, which allows the supported platforms to address larger datasets and run more virtual machines simultaneously.

Vragen over dit artikel

How long can the 1.2 V DDR4-2666 CL19 2Rx4 module sustain full load before thermal throttling?

The registered ECC RDIMM operates at the standard 1.2 V with CL19 timings; sustained-load thermal limits are defined by the server platform, not the module itself.

What is the typical noise and heat output when the 32 GB stick runs 24/7 in a Dell PowerEdge R740?

The DRAM has no moving parts and draws 1.2 V; all audible noise and exhaust heat come from the system fans and chassis airflow design.

Which existing DIMM type must the server already use so this 288-pin registered ECC module can be added?

The system must already populate registered ECC RDIMM slots; unbuffered or load-reduced DIMMs cannot be mixed with this module.
