Capacity 32GB

  • ECC registered design prevents data corruption in critical workloads
  • 32 GB capacity doubles memory headroom for virtualisation tasks
  • 2933 MHz DDR4 speed with CL21 latency accelerates server throughput
  • 2 V operation lowers power draw and thermal load
  • Validated for Supermicro X11DPFR-S, X11DPFR-SN, X11DPG-HGX2, X11DPG-OT-CPU, X11DPG-QT motherboards

Target System Compatibility

This 32GB DDR4 ECC registered DIMM is designed for Supermicro X11DPFR-S, X11DPFR-SN, X11DPG-HGX2, X11DPG-OT-CPU and X11DPG-QT motherboards. It serves server, workstation and NAS administrators who need to expand memory capacity on these specific platforms.

Registered ECC Requirement

The module uses registered ECC technology with a 2Rx4 organisation and will not function in standard desktop computers or alongside unbuffered memory. Buyers must verify their system requires registered ECC DDR4 before purchasing.

Standard Voltage Operation

Operating at 1.2V, the module runs at the standard DDR4 voltage without a heat spreader. It is backward compatible with 2133MHz, 2400MHz and 2666MHz bus speeds, allowing deployment in mixed-speed configurations while maintaining JEDEC-compliant power draw.

Questions about this item

What does the 2933 MHz rating actually deliver in a live server?

The module runs at DDR4 2933 (PC4-23400) with CL21 latency at 1.2 V, giving the rated bandwidth when the motherboard supports that speed.

How does the ECC registered interface affect compatibility?

This is a 288-pin ECC registered RDIMM (2Rx4) for workstations and servers; it will not work in standard desktops and cannot be mixed with unbuffered memory.

What physical slot and clearance does this DIMM need?

It fits a standard 288-pin DDR4 DIMM slot and has no heat spreader, so it clears typical server heatsinks and dense board layouts.
