OWC 512GB (4x128GB) DDR4 2933 ECC LRDIMM memory upgrade

SKU CH-KV6E-V4YTG

512 GB DDR4 2933 ECC load-reduced kit in four 128 GB modules for Supermicro X11SPD-F servers

  • Total capacity512 GB (4 × 128 GB)
  • Rated speedDDR4 2933 (PC4 23400)
  • CAS latencyCL21
  • Rated voltage1.2 V
  • Buffer typeLoad Reduced
  • Memory rank8Rx4

Capacity 512GB (4 x 128GB)

  • 512 GB total capacity with four 128 GB modules
  • DDR4 2933 speed for high-throughput server workloads
  • ECC load-reduced design protects data integrity in critical systems
  • 2 V operation reduces power draw in dense configurations
  • JEDEC and RoHS compliant for warranty-safe deployment

Server Memory Upgrade Kit

This 512GB kit contains four 128GB DDR4 2933 ECC Load Reduced DIMMs built for the Supermicro X11SPD-F motherboard. Modules run at PC4-23400 with CL21 latency and 1.2V operation. The 8Rx4 organisation and 288-pin form factor are specific to server and workstation platforms.

Replacing Lower Capacity LRDIMMs

The kit replaces smaller LRDIMM sets when the workload demands more than 512GB total capacity across four slots. A jump is worth it when current memory limits virtual-machine density, database caching or large-dataset processing on the X11SPD-F platform. Backward compatibility with 2133MHz, 2400MHz and 2666MHz buses allows phased upgrades without replacing the CPU.

Suits X11SPD-F Builders

This memory suits administrators expanding a Supermicro X11SPD-F server or workstation that already uses LRDIMM slots. It will not fit systems requiring unbuffered or standard registered ECC DIMMs. Builders needing different capacities, speeds or form factors should look at other modules.

Questions about this item

Will the 288-pin DDR4 LRDIMM modules fit the Supermicro X11SPD-F motherboard?

Yes, the kit is validated for the Supermicro X11SPD-F and uses the standard 288-pin DDR4 LRDIMM form factor required by that board.

What installation step is critical when seating these 128GB LRDIMMs?

Align the notch with the slot key, press straight down until both retention clips click, and populate all four channels identically to enable quad-channel operation.

When should the 1.2V ECC load-reduced modules be replaced?

Replace modules only if ECC correctable-error counts rise sharply or the system logs uncorrectable memory errors; otherwise they run for the server's service life.
