Four green 288-pin DDR4 LRDIMM modules in antistatic tray

OWC

OWC 1TB (4x256GB) DDR4 2933 ECC LRDIMM memory upgrade

SKU CH-98VF-W35CT

Kit of four 256 GB DDR4 2933 MHz ECC load-reduced DIMMs for compatible Supermicro server and workstation boards

Capacity 1TB (4 x 256GB)

  • 1TB total capacity for demanding server workloads
  • four 256GB modules deliver the full kit
  • DDR4 2933MHz CL21 for high-speed data handling
  • ECC load-reduced design protects data integrity
  • backward compatible with 2133, 2400 and 2666MHz systems

Server-grade ECC LRDIMM kit

This OWC kit provides 1 TB of DDR4 ECC load-reduced memory across four 256 GB modules. It runs at 2933 MHz with CL21 latency at 1.2 V on a 288-pin form factor. The kit targets Supermicro X11 server and workstation boards.

For multi-socket servers needing maximum capacity

The 8Rx4 organisation and load-reduced design suit dense virtualisation, in-memory databases and heavy compute nodes on the listed X11 platforms. It will not work in standard desktops, nor can it be mixed with unbuffered or registered ECC DIMMs. Buyers needing non-ECC memory or smaller capacities should look elsewhere.

1 TB total with four-channel headroom

Each 256 GB module fills a slot, giving 1 TB per populated channel on compatible boards. The kit comfortably handles large VM fleets and analytics workloads; capacity runs out when the platform’s maximum DIMM count or memory-controller limit is reached. Backward compatibility covers 2133, 2400 and 2666 MHz operation.

Questions about this item

Which motherboards must I already have for this 256 GB DDR4 2933 ECC LRDIMM kit to work?

The kit is validated for Supermicro X11DPD-L, X11DPD-M25, X11DPFF-SNR, X11QPL and X11SPA-T motherboards.

Can I keep my existing 2133 MHz DDR4 ECC LRDIMMs and add these 2933 MHz modules?

Yes, the modules are backward compatible with 2133 MHz, 2400 MHz and 2666 MHz ECC LRDIMM memory.

How do I confirm the 1 TB kit is running at PC4-23400 CL21 after installation?

Check the BIOS or OS memory report for 2933 MHz speed, CL21 latency, 1.2 V voltage and ECC Load Reduced status on all four DIMMs.
