4GB DDR3L 1600 Desktop DIMM

This 4GB DDR3L module runs at 1600MHz with a low 1.35V operating voltage. The 240-pin unbuffered design fits standard desktop DIMM slots. It is built as a direct replacement for the Samsung M379B5273DH0-YK0 part number.

Suitable for DDR3L low-voltage desktop upgrades

Systems that require DDR3L 1.35V memory at 1600MHz can use this module. Builders needing higher capacity per slot, ECC error correction, or registered buffering should look at other parts.

1.35V DDR3L voltage specification

The 1.35V low-voltage rating is the single specification that determines whether this module matches the system's memory controller requirements. Verify that the platform supports DDR3L before ordering.

Questions about this item

Does my motherboard need a 240-pin DDR3 slot for this module?

Yes, the stick uses a 240-pin DIMM form factor and runs at DDR3L 1600 (PC3L-12800), so the board must provide a matching DDR3 slot.

Will it run correctly if I keep my existing 1.5 V DDR3 DIMMs installed?

The module operates at 1.35 V; most boards will down-volt all slots to the lowest voltage present, but stability depends on the motherboard's memory controller.

How can I confirm the kit is running at 1600 MHz after installation?

Check the memory frequency in BIOS or with a tool such as CPU-Z; it should report 1600 MT/s (PC3-12800) at 1.35 V.
