OWC 256GB DDR4 3200 CL22 8Rx4 288-pin ECC LRDIMM memory upgrade

SKU CH-44GQ-TEMZ6

A single 256 GB DDR4 3200 CL22 8Rx4 288-pin 1.2 V ECC load-reduced DIMM for Gigabyte G242-Z12, G262-ZO0, G292-Z40, G292-Z42 and G292-Z43 servers and workstations

Capacity 256GB

  • Single 256GB module maximises server capacity
  • ECC load-reduced design ensures data integrity
  • 3200MHz CL22 speed accelerates workloads
  • 2V operation lowers power draw
  • Backward compatible with 2133, 2400, 2666, 2933MHz systems

Single 256GB LRDIMM module

This single-module upgrade delivers 256GB of DDR4 ECC load-reduced memory rated at 3200MHz CL22. It is built for Gigabyte G242-Z12, G262-ZO0, G292-Z40, G292-Z42 and G292-Z43 server platforms that require 288-pin LRDIMMs operating at 1.2V. The module targets administrators expanding capacity in compatible workstations, servers or NAS systems without mixing memory types.

LRDIMM-only compatibility constraint

The module uses the ECC load-reduced standard and will not work in standard desktop computers or in systems that accept only unbuffered or registered ECC DIMMs. Mixing this LRDIMM with other ECC types is not supported. Backward compatibility covers 2133MHz, 2400MHz, 2666MHz and 2933MHz bus speeds, so the module can slot into older DDR4 server platforms that run at those lower frequencies.

256GB per slot headroom

A single 256GB stick provides very high density for memory-intensive workloads such as large databases, virtualization clusters or high-resolution rendering. Capacity scales with the number of populated slots on the host board, so total system memory depends on the platform’s maximum supported DIMM count. The practical limit is the server’s qualified memory population rules, not the module itself.

Questions about this item

Should I choose the single 256GB module or combine smaller sticks to reach the same capacity?

The product is supplied as one 256GB DDR4 3200 CL22 8Rx4 LRDIMM; adding smaller modules would require matching rank, voltage and ECC type, so the single stick is the simplest path to 256GB.

What does the 3200MHz rating deliver once the module is installed in a compatible server?

The module runs at DDR4 3200 PC4-25600 with CL22 latency at 1.2V, and will down-clock automatically to 2933, 2666, 2400 or 2133MHz if the platform requires it.

How does the 288-pin ECC load-reduced interface affect what the memory can do in practice?

The 288-pin LRDIMM format provides ECC error correction and reduced electrical load for high-density server boards; it cannot be mixed with unbuffered or registered DIMMs and is not compatible with standard desktop systems.
