4GB DDR3 UDIMM for desktop upgrades

This Micron module supplies 4GB of DDR3 memory at 1333 MHz with CL9 latency and 1.5 V operation. The 240-pin UDIMM form factor fits standard desktop DIMM slots. It is suited to owners of older systems needing a direct replacement or a simple capacity increase.

Sustained load behaviour with 2Rx8 organisation

The dual-rank 2Rx8 layout using sixteen 256x8 chips spreads refresh cycles across both ranks, helping maintain throughput during extended workloads. Rated PC3-10600 bandwidth supports continuous data transfer at the specified speed without thermal throttling under normal case airflow. Builders who require ECC error correction or registered buffering should select a different module type.

Questions about this item

How much power does the 1.5V DDR3 module draw when running continuously?

The module operates at 1.5 volts, the standard voltage for DDR3 UDIMMs, so power draw stays within typical DDR3 limits for a 4GB stick.

What motherboard slot is required for this 240-pin UDIMM to work?

It needs a desktop DDR3 DIMM slot with 240 pins; the board must support DDR3 1333 (PC3-10600) memory.
