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.

Perguntas sobre este artigo

Will this 240-pin DDR3 UDIMM fit my server's standard DIMM slots?

Yes, the module uses the 240-pin DDR3 DIMM form factor standard for unbuffered ECC server memory.

Do I need to configure anything in the BIOS after installing this CL13 1.5V module?

Most servers detect the 1866MHz speed and CL13 timings automatically; just ensure ECC is enabled in BIOS if not on by default.

How can I tell when this ECC module should be replaced?

ECC corrects single-bit errors silently; replace the module if your system logs show recurring corrected errors or uncorrectable memory errors.
