Capacity and Module Format

This A-Tech 8GB DDR3 1600 ECC UDIMM module provides a single 8GB stick built to the 240-pin DIMM standard. It runs at 1600 MHz with a CL11 latency and 1.50V voltage, using Micron chips in a 2Rx8 organisation. The unbuffered ECC design suits servers and workstations that require error correction without registered buffering.

Systems that accept unbuffered ECC

This memory fits servers and workstations that support DDR3 ECC UDIMM modules at 1600 MHz. It will not work in platforms that require registered or load-reduced DIMMs, nor in consumer boards that lack ECC support in the chipset and BIOS. Buyers needing higher density per slot or registered signalling must select a different module type.

The 2Rx8 ECC UDIMM specification decides fit

The combination of unbuffered operation, ECC functionality, and dual-rank 2Rx8 organisation determines whether this part is compatible with a given motherboard. Verify that the system documentation explicitly lists DDR3 1600 ECC UDIMM support with 2Rx8 population rules before purchase.

Questions about this item

Should I choose the 2Rx8 version or a single-rank alternative for my server?

The module is built as 2Rx8, meaning it has two ranks of x8 chips; this density is what the Micron MT18JSF1G72AZ-1G6E1 specifies, so select this version when your system requires that exact rank configuration.

What does the DDR3 1600 (PC3-12800) rating deliver in an actual server?

It runs at 1600 MT/s with CL11 latency at 1.50 V, providing the standard DDR3-1600 data rate for compatible platforms.

Is the 240-pin UDIMM interface compatible with registered DIMM slots?

No, the module is an unbuffered ECC UDIMM on a 240-pin DDR3 form factor and will only fit motherboards that accept UDIMMs, not registered DIMM slots.
