A-Tech 4GB DDR3 1600 ECC UDIMM

This 4GB DDR3 module runs at 1600MHz with a PC3-12800 rating and CL11 latency. It operates at the standard 1.50V DDR3 voltage and uses an unbuffered ECC design with a single-rank 1Rx8 organisation. The 240-pin DIMM form factor is built for server and workstation platforms that require error-correcting memory.

Suited for Dell A6994479 compatible systems

This module serves as a direct replacement for the Dell A6994479 part number in supported servers and workstations. Builders who need registered or load-reduced DIMMs, higher capacities per slot, or non-ECC memory should look elsewhere because this is an unbuffered ECC UDIMM limited to 4GB per stick.

Single-rank 1Rx8 ECC UDIMM specification

The 1Rx8 rank configuration and unbuffered ECC type determine whether the memory controller can address this module correctly. Verify that your platform accepts unbuffered ECC UDIMMs with this rank structure before purchasing, as registered or different-rank modules are not interchangeable.

Questions about this item

Will the ECC UDIMM need replacement if a memory cell fails?

ECC corrects single-bit errors on the fly, so the module continues operating without replacement for correctable faults.

What limit appears first when the 1600 MHz module runs sustained workloads?

The CL11 latency at 1.50 V sets the timing ceiling before thermal or bandwidth limits are reached.

How much heat and power does the 1Rx8 DDR3 stick produce all day?

At standard 1.50 V DDR3 voltage the unbuffered 240-pin DIMM draws minimal power and runs cool in typical server airflow.
