  • 2 V operation reduces power draw per module
  • Compatible with five Supermicro X11 motherboard models

Server-grade DDR4 upgrade

This OWC 32GB DDR4 2933MHz CL21 ECC Registered RDIMM targets administrators expanding Supermicro X11 motherboards such as X11DGQ, X11DPD-L, X11DPD-M25, X11DPFF-SN and X11DPFF-SNR. It replaces Supermicro part numbers including MEM-DR432LC-ER29 and MEMDR432LCL01ER29 for direct drop-in installation. The module is not suitable for standard desktop boards or consumer laptops.

Sustained error-corrected throughput

Registered buffering and ECC logic maintain data integrity across continuous workloads in servers, workstations and NAS systems. The 1.2V DDR4 modules operate at PC4-23400 speed while remaining backward compatible with 2133MHz, 2400MHz and 2666MHz bus clocks. Dual-rank 2Rx4 organisation distributes load evenly during long compute sessions.

Platform verification checklist

Confirm the motherboard is one of the listed Supermicro X11 models before ordering. Ensure all populated slots use registered ECC DIMMs; mixing with unbuffered memory is not supported. Verify the system BIOS recognises DDR4 2933MHz registered modules at 1.2V. Check available 288-pin slots for physical clearance.

Klausimai apie šią prekę

How much power does this 1.2V DDR4 2933MHz RDIMM draw when the server runs continuously?

Each module operates at 1.2V, the standard DDR4 voltage, so power draw stays within JEDEC limits for registered ECC DIMMs at this speed.

What must the motherboard support for this 2Rx4 registered ECC DIMM to function?

The board must accept 288-pin DDR4 registered ECC memory and run at 1.2V; it will not work with unbuffered or non-ECC slots.

Will this 32GB PC4-23400 module run stably beside older 2133MHz or 2400MHz DDR4 ECC RDIMMs?

Yes, it is backward compatible with 2133MHz, 2400MHz and 2666MHz registered ECC DIMMs; the system will clock all modules to the lowest common speed.
