SAMSUNG M378B5173QH0-YK0 4GB DDR3 1600MHz desktop RAM

SKU CH-8Y7P-J6H08

Adds 4 GB of DDR3 memory at 1600 MHz with 1.35 V low-voltage operation

  • 4GB capacity for everyday multitasking
  • 1600MHz data rate for responsive performance
  • DDR3 SDRAM technology for broad desktop compatibility
  • Low 1.35V operation reduces power draw
  • CL11 latency with 1.5ns cycle time

4GB DDR3 1600MHz desktop module

This 4GB DDR3 DIMM runs at 1600MHz with a 1.35 V operating voltage. It uses a 240-pin PC3L-12800 interface and carries CL11 timing at a 1.5ns cycle time. The single-rank 1Rx8 organisation keeps the layout simple for standard desktop boards.

Who this suits and who it does not

This module suits owners of older desktops that require low-voltage DDR3 memory for a straightforward capacity increase. Builders needing ECC error correction, higher frequencies, or larger single-stick capacities should look at other memory types that provide those specific features.

Deciding specification: 1.35 V low-voltage DDR3

The 1.35 V rating identifies this stick as PC3L low-voltage DDR3, which is electrically different from standard 1.5 V DDR3 modules. A motherboard that only supports the higher voltage will not run this memory reliably, so confirming the board's voltage requirement is the single check that determines compatibility.

Questions about this item

How much power does the 1.35 V DDR3 module draw during continuous operation?

The module operates at 1.35 V, which is lower than standard DDR3 voltage, reducing heat output and power draw during all-day use.

What motherboard slot and memory type are required for this 240-pin stick?

A desktop motherboard with a DDR3 240-pin DIMM slot is needed; the board must accept 1.35 V PC3L-12800 memory.

Will the CL11 timing work alongside modules with different CAS latency?

The module runs at CL11; when mixed with other DDR3 sticks the system will operate at the slowest common timing and voltage.
