Server-grade ECC LRDIMM upgrade

This 128GB DDR4 module runs at 3200MHz with CL22 latency and 1.2V operation. It uses a 288-pin load-reduced form factor with 4Rx4 organisation and built-in ECC. The memory is designed for Gigabyte H262-P60, H262-P61, H262-PC0, H262-PC1 and H262-PC2 server and workstation platforms.

Load-reduced architecture enables high density

The load-reduced design reduces electrical load on the memory bus, allowing this 128GB capacity in a single DIMM. It cannot be mixed with unbuffered or standard registered ECC modules. The module is backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz bus speeds. No heat spreader is fitted, relying on chassis airflow.

DDR4 LRDIMM platform constraints

This memory fits only systems that support DDR4 ECC load-reduced DIMMs. Standard desktop motherboards and consumer laptops will not accept it. The 288-pin interface is keyed differently from unbuffered or registered DIMMs, preventing incorrect installation. Maximum capacity per channel depends on the specific platform memory controller.

Questions about this item

Will the 128GB DDR4 3200 ECC LRDIMM need any firmware updates or component replacements during its service life?

No firmware updates or component replacements are required for the 128GB DDR4 3200 ECC LRDIMM; the module is a solid-state component with no moving parts and is designed to operate for the lifetime of the compatible Gigabyte H262 series systems.

What is the first limit reached when the 128GB DDR4 3200 ECC LRDIMM runs at full load continuously?

The primary limit under sustained full load is the JEDEC-defined maximum operating temperature for the DDR4 DRAM chips; the module has no heat spreader, so chassis airflow must keep the chips within specification.

How much heat and power does the 128GB DDR4 3200 ECC LRDIMM produce when installed in a Gigabyte H262 server running 24/7?

The module operates at 1.2V with a 4Rx4 load-reduced design; power draw scales with capacity and rank count, and waste heat is dissipated directly from the DRAM packages into the server's forced-air cooling path.
