Eight green 288-pin DDR4 LRDIMM modules in a row

OWC

OWC 2TB 8x256GB DDR4 2933 PC4-23400 CL21 ECC LRDIMM memory upgrade

SKU CH-57Q3-PZWGB

Eight 256 GB DDR4 2933 ECC load-reduced DIMMs totalling 2 TB for Supermicro X11SPA-TF servers

Capacity 2TB (8 x 256GB)

  • Massive 2 TB capacity with eight 256 GB modules
  • Server-grade ECC load-reduced DIMMs protect data integrity
  • 2933 MHz DDR4 speed with CL21 latency for responsive workloads
  • Runs at 1.2 V for lower power draw and heat
  • Backward compatible with 2133, 2400 and 2666 MHz systems

Server memory kit

This OWC kit supplies 2TB of DDR4 memory across eight 256GB LRDIMM modules rated at PC4-23400 2933MHz CL21. It is built for Supermicro X11SPA-TF motherboards in workstation, server and NAS deployments that require ECC load-reduced technology.

Compatibility check

Verify that your platform accepts DDR4 ECC load-reduced DIMMs and cannot use unbuffered or registered ECC memory in the same system. The modules operate at 1.2V and are backward compatible with 2133MHz, 2400MHz and 2666MHz bus speeds when the board dictates a lower frequency.

Sustained operation

JEDEC-standard construction and load-reduced architecture keep electrical loading low across all populated slots during continuous workloads. ECC correction maintains data integrity over long runs while the 1.2V supply limits thermal output under sustained utilisation.

Questions about this item

What comes in the kit and do I need anything else to install it?

The kit contains eight 256 GB DDR4 2933 CL21 ECC Load-Reduced 288-pin DIMMs. No extra parts or tools are required for installation in a compatible server or workstation.

How do I decide between the available capacities or speeds for this Supermicro X11SPA-TF upgrade?

This kit is a fixed 2 TB set of eight 256 GB modules running at 2933 MHz with CL21 latency. The modules also operate at 2133, 2400 and 2666 MHz if the platform requires a lower speed.

What does the 2933 MHz rating mean once the memory is installed in a real server?

The modules run at 2933 MT/s with CAS latency 21 at 1.2 V. If the motherboard only supports 2133, 2400 or 2666 MT/s, the DIMMs automatically down-clock to the highest supported speed while keeping ECC load-reduced operation.
