  • 4GB capacity adds multitasking headroom for everyday desktop workloads
  • DDR3L 1600MHz speed delivers responsive data throughput at PC3-12800 bandwidth
  • Low 1.35V operation reduces power draw and heat in compatible systems
  • CL11 latency timing supports stable performance at rated frequency
  • 240-pin unbuffered DIMM fits standard desktop memory slots

What this module replaces

This 4GB DDR3L DIMM is a direct replacement for Micron MT8KTF51264AZ-1G6N1 and MT8KTF51264AZ-1G6P1. It fits desktop systems that require a 240-pin unbuffered non-ECC module at 1.35V. The single stick adds 4GB of capacity for everyday workloads.

Voltage and speed decide fit

The module runs at 1600MHz with CL11 latency at 1.35V, matching the PC3L-12800 specification. Only systems that support DDR3L at this voltage and frequency will operate correctly. Verify the motherboard documentation before purchase.

Tested reliability only

Every unit undergoes quality-assurance testing for dependable operation. No heat spreader, extra software or bundled accessories are included. The package contains the memory module alone.

Questions about this item

What does the 1600 MHz rating mean for actual desktop performance?

The module runs at 1600 MHz with CL11 timing, delivering PC3-12800 bandwidth for faster application loading and smoother multitasking on compatible DDR3 systems.

How does the DDR3L 1.35 V interface affect power use and compatibility?

DDR3L at 1.35 V reduces power draw versus standard 1.5 V DDR3 while remaining backward compatible with 1.5 V slots; the memory controller negotiates the lower voltage automatically.

Will the 240-pin DIMM fit my motherboard's memory slots?

Yes, the module uses the standard 240-pin DDR3 DIMM form factor; verify your board supports DDR3L 1.35 V unbuffered non-ECC memory before installing.
