Server DDR3 8GB module

This A-Tech 8GB DDR3 1600 ECC UDIMM is built for server and workstation systems that require error-correcting unbuffered memory. It replaces the HP 677034-001 part and delivers 1600MHz speed at standard 1.50V voltage. The module uses a 2Rx8 rank configuration with major brand chipsets for reliable operation.

240-pin DIMM form factor

The single specification that decides fit is the 240-pin DDR3 DIMM interface; only systems accepting DDR3 unbuffered ECC UDIMMs at 1600MHz can use this module. It runs at CL11 latency and 1.50V, so platforms limited to registered or load-reduced DIMMs, or those requiring a different voltage or pin count, will not be compatible.

Quality testing and lifetime warranty

Every module undergoes quality assurance testing to verify dependable performance before shipment. The purchase includes a lifetime warranty and access to United States based technical support for assistance before, during, and after installation.

Questions about this item

How does the 1600 MHz speed translate to real-world throughput in a server?

The module runs at 1600 MHz, delivering a peak transfer rate of PC3-12800, so sustained bandwidth in a real machine will approach that figure depending on the memory controller and workload.

What does the DDR3 240-pin unbuffered ECC interface limit in practice?

As an unbuffered ECC DIMM, it connects directly to the memory controller without a register, capping maximum capacity per channel compared to registered modules while still providing error correction.

Will the 240-pin DIMM fit a standard server memory slot?

Yes, it uses the standard 240-pin DDR3 DIMM form factor, so it fits any server or workstation slot designed for DDR3 unbuffered ECC memory.
