Server DDR3 ECC module for legacy workstations

This 4 GB DDR3 1866 MHz ECC UDIMM replaces the Elpida EBJ40EG8BFWB-JS-F part in servers and workstations. It runs at CL13 latency with standard 1.5 V DDR3 voltage. The unbuffered single-rank design suits systems that require registered-free memory.

240-pin DIMM with major-brand chipset

The module uses a 240-pin DDR3 DIMM form factor built on a major-brand chipset. Unbuffered ECC circuitry provides error correction without the latency penalty of registered memory. Standard 1.50 V operation matches original DDR3 platform specifications for direct installation.

Lifetime warranty with US-based support

A-Tech backs every module with a lifetime warranty and includes complimentary United States technical support before, during and after purchase. All units undergo quality-assurance testing to verify dependable performance. Buyers who need higher-density kits or registered ECC memory should look elsewhere.
