A-Tech 32GB DDR3 1866 ECC LRDIMM 4Rx4 Server Memory

32GB DDR3 1866 LRDIMM for Servers

This 32GB DDR3 1866MHz ECC Load Reduced DIMM is built for server and workstation platforms that require registered memory. It operates at PC3-14900 speed with CL13 latency and 1.5V standard voltage. The module uses a 4Rx4 organisation and Samsung chipset for data integrity in multi-socket systems. It suits administrators upgrading compatible Samsung part numbers.

Installing DDR3 LRDIMM Modules

The 240-pin DIMM seats in standard DDR3 slots, but the platform must support Load Reduced technology and 4Rx4 density. Mixing LRDIMMs with standard RDIMMs or UDIMMs will prevent boot. Verify the system qualified vendor list for the exact Samsung M386B4G70BM0-CMA3, M386B4G70DM0-CMA3 or M386B4G70DM0-CMA4 part numbers before ordering. Incorrect population order across channels is the most common cause of POST failure.

Sustained Load Behaviour on DDR3 1866

Under continuous workloads the ECC circuitry corrects single-bit errors without halting the server. Load Reduced buffering lowers electrical load on the memory controller, allowing higher total capacity per channel at 1866MHz. The 1.5V supply remains stable during extended compute passes. Modules without ECC or Load Reduced buffering cannot deliver the same error resilience for 24/7 operation.
