OWC 1TB (4x256GB) DDR4 2933 PC4-23400 CL21 8Rx4 288-pin 1.2V ECC LRDIMM Kit for Supermicro X11SPA-TF

SKU CH-Y3Y4-GTM55

ECC load-reduced DDR4 kit provides 1 TB across four 256 GB modules at 2933 MHz CL21 for Supermicro X11SPA-TF servers

Capacity 1TB (4 x 256GB)

  • 1TB kit with four 256GB modules expands server capacity
  • DDR4 2933MHz CL21 speed accelerates data throughput
  • ECC load-reduced design ensures error correction for critical workloads
  • 2V operation reduces power draw in dense configurations
  • Backward compatible with 2133, 2400 and 2666MHz systems

Targeted Server Memory Upgrade

This kit supplies four 256GB ECC Load-Reduced DDR4 modules for a total of 1TB capacity. It is engineered specifically for the Supermicro X11SPA-TF motherboard used in workstations, servers and NAS systems. The modules operate at 1.2V and follow the 288-pin LRDIMM form factor.

Replacing Lower-Capacity Registered DIMMs

The upgrade moves a system from standard registered ECC memory to load-reduced ECC, enabling the larger 256GB per module density that registered DIMMs cannot reach. The jump is worthwhile when the workload demands more memory channels than the board provides or when the application exceeds the registered DIMM limit. Mixing with unbuffered or registered ECC memory is not supported.

Sustained Load Behaviour

Rated at PC4-23400 2933MHz CL21, the modules maintain JEDEC-standard timing under continuous server workloads. Backward compatibility with 2133MHz, 2400MHz and 2666MHz allows the kit to run stably if the platform downclocks the memory bus. ECC correction operates continuously to protect data integrity during extended operations.

Domande su questo articolo

Will these 288-pin LRDIMMs fit the Supermicro X11SPA-TF DIMM slots?

Yes, the 288-pin ECC Load Reduced DIMM form factor matches the X11SPA-TF memory slots exactly.

What is the correct installation sequence for the four 256 GB modules on this board?

Populate all four channels with one module each, following the motherboard's channel-colour guide; the step often missed is seating both latches until they click.

When will the 1.2 V DDR4 LRDIMMs need replacement in a 24/7 server?

JEDEC-standard DDR4 at 1.2 V is rated for continuous operation; plan replacement only if ECC correctable errors rise or a module fails diagnostics.
