Eight green DDR4 LRDIMM sticks with gold contacts in anti-static packaging

OWC

OWC 2TB (8x256GB) DDR4 3200 CL22 ECC Load Reduced LRDIMM 288-pin memory upgrade

SKU CH-P0HQ-AKZ62

Eight 256 GB DDR4 3200 CL22 ECC load-reduced DIMMs totalling 2 TB for Supermicro H12SSL and H12SSW servers

Capacity 2TB (8 x 256GB)

  • Massive 2 TB capacity from eight 256 GB modules
  • DDR4 3200 CL22 speed for high-throughput server workloads
  • ECC load-reduced design protects data integrity in critical systems
  • Backward compatible with 2133, 2400, 2666 and 2933 MHz platforms
  • JEDEC and RoHS compliant for warranty-safe upgrades

Server-grade 2 TB DDR4 kit

This OWC upgrade kit delivers 2 TB of DDR4 memory across eight 256 GB load-reduced DIMMs. It runs at 3200 MHz with CL22 latency and 1.2 V operation. The modules are JEDEC-standard and RoHS compliant for warranty-safe installation in qualified Supermicro motherboards.

For multi-socket servers only

The LRDIMM ECC design targets workstations, servers and NAS systems that specifically support load-reduced memory. It will not work in standard desktop PCs and cannot be mixed with unbuffered or registered ECC DIMMs. Buyers needing ordinary desktop RAM should look elsewhere.

Steady throughput at scale

All eight modules maintain 3200 MHz CL22 timings under sustained load, with backward compatibility at 2933, 2666, 2400 and 2133 MHz. The 8Rx4 organisation and load-reduced buffer keep signal integrity stable when every slot is populated for long-running compute tasks.

Questions about this item

Does the 288-pin LRDIMM kit require a motherboard that supports ECC load-reduced memory?

Yes, the modules are ECC load-reduced DDR4 DIMMs and will only work in systems designed for that memory type; they cannot be mixed with unbuffered or registered ECC memory.

Will the 3200 MHz modules run at their rated speed on a platform that only supports 2133 MHz DDR4?

The kit is backward compatible with 2133 MHz, 2400 MHz, 2666 MHz and 2933 MHz platforms, so it will operate at the highest speed the motherboard allows.

How can I confirm the full 2 TB capacity is recognised after installing the eight 256 GB modules?

Check the system BIOS or operating system memory report; it should show 2 TB total across all populated slots running at the configured speed with ECC active.
