OWC
Eight 128 GB DDR4-2400 ECC load-reduced DIMMs add 1 TB of registered server memory with CL17 latency at 1.2 V
Capacity 1TB (8 x 128GB)
This OWC kit delivers 1TB of DDR4 capacity across eight 128GB LRDIMM modules. It targets administrators upgrading enterprise servers, workstations or NAS systems that require registered ECC memory with load-reduced architecture.
The modules operate at PC4-19200 speed with CL17 latency and 1.2V voltage. Backward compatibility extends to 2133MHz systems, but the load-reduced design cannot be mixed with unbuffered DIMMs and will not function in standard desktop platforms.
Each 288-pin module seats vertically in registered DIMM slots without cables or drivers. The most common issue is attempting to populate consumer motherboards that lack LRDIMM support, which prevents the system from posting.

The kit is supplied as eight 128GB LRDIMMs totalling 1TB; choose this version when your server or workstation has eight available 288-pin DDR4 slots and supports 4Rx4 load-reduced ECC memory.
It runs at 2400MHz with CL17 latency at 1.2V, and will also operate at 2133MHz if the platform requires the lower speed.
The 288-pin LRDIMM form factor fits only server, workstation or NAS boards that accept DDR4 load-reduced ECC; it cannot be used in standard desktops or mixed with unbuffered modules.
