Eight green 288-pin DDR4 LRDIMM modules with black chips and gold contacts

OWC

OWC 2TB (8×256GB) DDR4 3200 CL22 8Rx4 288-pin 1.2V ECC Load Reduced LRDIMM memory upgrade

SKU CH-GZE2-WXNB8

Eight 256 GB DDR4 3200 CL22 ECC load-reduced DIMMs totalling 2 TB for compatible Supermicro servers and workstations

Capacity 2TB (8 x 256GB)

  • 2 TB capacity in eight 256 GB modules
  • DDR4 3200 MT/s CL22 for high-throughput workloads
  • ECC load-reduced design protects data integrity
  • 2 V operation reduces server power draw
  • Validated for Supermicro H12DSG-O-CPU, H12DST-B, H12DSU-iN, H12SSL-C, H12SSL-i

Server-grade capacity

This kit delivers 2TB of DDR4 memory across eight 256GB load-reduced DIMMs. It is built for Supermicro H12DSG-O-CPU, H12DST-B, H12DSU-iN, H12SSL-C and H12SSL-i motherboards in server, workstation and NAS roles. ECC load-reduced technology is required; the modules will not work in standard desktops or alongside unbuffered or registered ECC memory.

Replaces lower-density registered DIMMs

The upgrade suits administrators who have exhausted registered ECC slots and need higher per-slot density without changing platforms. It is not for systems that only accept unbuffered or standard registered ECC modules, nor for builds that cannot populate all eight slots. Backward compatibility covers 2133, 2400, 2666 and 2933MHz operation when the platform requires it.

Sustained load behaviour

CL22 latency at 3200MHz and 1.2V operation keep power draw predictable during long compute runs. JEDEC-standard signalling and load-reduced buffering reduce electrical load on the memory controller, helping maintain stability in multi-socket servers running continuous workloads.

Questions about this item

Will the 288-pin ECC Load Reduced DIMM modules fit my Supermicro H12DSG-O-CPU motherboard?

Yes, the kit is validated for Supermicro H12DSG-O-CPU, H12DST-B, H12DSU-iN, H12SSL-C and H12SSL-i boards. Each 256 GB module uses the standard 288-pin DDR4 LRDIMM form factor required by those platforms.

What is the correct installation sequence for the eight 256 GB LRDIMMs, and what step is commonly missed?

Populate all eight slots identically; do not mix these 8Rx4 LRDIMMs with unbuffered or registered ECC DIMMs. The step often missed is verifying the BIOS recognises the full 2 TB at 3200 MHz CL22 before loading the OS.

When will the 1.2 V DDR4 LRDIMMs need replacement, and what indicates end of life?

These JEDEC-compliant modules carry a limited lifetime warranty. Replace them only if memory diagnostics report uncorrectable ECC errors or the system fails to POST with all eight installed.
