OWC 256GB DDR4 3200 CL22 ECC LRDIMM 288-pin 1.2V memory upgrade

Server Memory Upgrade

This single 256GB DDR4 LRDIMM operates at 3200MHz with CL22 latency and 1.2V power draw. It targets administrators expanding Gigabyte H252-Z12, H261-Z60, H261-Z61, H262-NO0 or H262-NO1 platforms. The ECC load-reduced design suits multi-socket servers, workstations and NAS appliances that require registered buffer relief. It will not function in standard desktop motherboards or alongside unbuffered or registered ECC modules.

Capacity and Headroom

The 256GB density on one 288-pin module lets a compatible board reach very high memory totals with fewer occupied slots. Workloads such as large virtualisation clusters, in-memory databases or heavy rendering caches benefit from the extra headroom. Systems limited to lower per-slot maximums or those requiring mixed rank populations will hit a ceiling before this module can be fully utilised. Buyers needing smaller increments or non-ECC memory should look elsewhere.

DDR4 Interface Limits

Rated PC4-25600 at 3200MHz, the module also runs at 2133MHz, 2400MHz, 2666MHz and 2933MHz when the memory controller dictates. Peak throughput is bound by the DDR4 bus width and the platform’s maximum supported data rate. Latency scales with each lower step, so real-world bandwidth will follow the slowest active channel. Boards capped below 3200MHz cannot exploit the top speed grade.
