A-Tech 4GB DDR3 1866MHz ECC UDIMM 2Rx8 Server Memory

A-Tech 4GB DDR3 1866MHz ECC UDIMM

This A-Tech module delivers four gigabytes of DDR3 1866MHz server memory with ECC error correction and an unbuffered design. It targets administrators maintaining HP systems that require the 754729-001 or 733483-001 part numbers. The 2Rx8 organisation and CL13 latency suit typical dual-channel configurations in rack or tower servers.

Replaces HP 754729-001 and 733483-001 modules

The stick is a direct equivalent for the listed HP part numbers, allowing a like-for-like swap when a DIMM fails or when expanding capacity within the original specification. The jump is worth it when the platform still runs DDR3 and the memory controller supports unbuffered ECC at 1.50V. Systems that demand registered DIMMs or a higher rank count will not accept this module.

DDR3 240-pin DIMM interface limits

The DDR3 interface caps transfer rates at 1866MT/s and requires a 240-pin slot keyed for unbuffered ECC UDIMMs. Voltage is fixed at 1.50V, so platforms limited to 1.35V low-voltage DDR3 cannot use this memory. Maximum capacity per channel is bounded by the memory controller and the number of physical slots, not by the module itself.
