32GB DDR4 ECC Registered RDIMM

This 32GB DDR4 2933MHz module is built for servers, workstations and NAS systems that require registered ECC memory. It will not work in standard desktop computers and cannot be mixed with unbuffered DIMMs. Buyers who need memory for a consumer motherboard should look elsewhere.

Registered ECC 2Rx4 at 2933MHz CL21

The single specification that decides compatibility is the registered ECC 2Rx4 organisation running at DDR4 2933 (PC4-23400) with CL21 latency and 1.2V. Systems must support registered ECC DDR4 and accept 288-pin RDIMMs; unbuffered or non-ECC platforms will not recognise this module.

JEDEC compliant with backward speed support

The module meets JEDEC and RoHS standards and is rated for 2933MHz while also operating at 2133MHz, 2400MHz and 2666MHz when the platform dictates a lower speed. No heat spreader is included, so airflow in the chassis must be sufficient for bare DRAM.

Questions about this item

What does the 2933 MHz rating mean once this module is installed in a server?

It runs at 2933 MT/s, delivering DDR4-2933 bandwidth when the platform supports that speed.

What does the PC4-23400 designation cap in practice?

PC4-23400 is the JEDEC standard name for DDR4-2933; the module will operate at the highest common speed the system allows, down to 2133 MT/s.

What physical slot does this 288-pin RDIMM need?

It fits a standard 288-pin DDR4 RDIMM socket in a server, workstation or compatible NAS system.
