Server-grade ECC UDIMM for DDR3 systems

This 4 GB DDR3 1600 module delivers error-correcting code protection in an unbuffered 240-pin form factor. It runs at CL11 latency with a standard 1.5 V supply and uses a 2Rx8 rank organisation built on major-brand chips.

Fits DDR3 server or workstation boards

The module installs directly into any 240-pin UDIMM socket that accepts PC3-12800 speeds and 1.5 V operation. ECC functionality requires a platform that enables error correction; non-ECC or registered-only boards cannot use this memory.

Single-module kit simplifies incremental upgrades

Supplied as a standalone 4 GB stick, it lets administrators add capacity one slot at a time without buying matched pairs. A-Tech tests every unit before shipment and backs it with lifetime US-based technical support.

Questions about this item

Will the 2Rx8 organisation and CL11 latency become a bottleneck under sustained server workloads?

The module runs at DDR3 1600 with CL11 latency and a 2Rx8 layout, so bandwidth and latency are fixed at those specifications for the workload you apply.

How much heat and power should I expect from the 1.5 V unbuffered ECC DIMM running continuously?

Operating at the standard 1.5 V DDR3 voltage, the 4 GB unbuffered ECC DIMM draws typical DDR3 power and produces heat consistent with that voltage level.

Does my motherboard need to support 240-pin DDR3 ECC unbuffered memory for this module to work?

Yes, the system must accept 240-pin DDR3 ECC unbuffered DIMMs at 1600 MHz; otherwise the module will not be recognised or will run at a lower speed.
