32GB DDR3 LRDIMM for HP Servers

This 32GB DDR3 1866MHz ECC Load Reduced DIMM is a compatible replacement for HP part 773081-001. It targets administrators upgrading memory capacity in supported HP server or workstation platforms. The single module delivers 32GB using a 4Rx4 organisation at 1.5V standard voltage.

Verify DDR3 LRDIMM support and rank limits

Confirm that your system accepts DDR3 LRDIMM modules and supports 4Rx4 density at 1866MHz speed. Check the platform documentation for maximum modules per channel and total capacity limits before ordering. The 240-pin form factor requires a matching DDR3 slot; other generations will not fit.

Tested module with lifetime coverage

Each unit undergoes quality assurance testing for dependable operation in server environments. The module ships as a standalone 32GB stick without additional cables, brackets or software utilities. A-Tech provides lifetime warranty coverage and US-based technical support for the life of the product.
