4GB DDR3L desktop module

This A-Tech module adds four gigabytes of DDR3L memory to a desktop system. It runs at 1866 MHz with a PC3L-14900 rating and operates at 1.35 V. The unbuffered, non-ECC design suits standard consumer motherboards.

Steady throughput at rated speed

The module maintains its 1866 MHz frequency during extended workloads rather than throttling after a short burst. Low-voltage operation keeps power draw modest while the tested frequency stays consistent across sustained read and write cycles.

240-pin DIMM with lifetime backing

A 240-pin gold-edge connector fits the standard DDR3 DIMM slot without adapters. Each stick passes A-Tech quality-assurance testing and ships with a lifetime warranty plus US-based technical support. Verify your board's DDR3L compatibility before ordering.

Questions about this item

Will this 240-pin module fit my desktop motherboard?

It fits any desktop board with a DDR3 DIMM slot that accepts 1.35 V unbuffered memory. Check your manual for supported speeds and maximum capacity per slot.

Can I mix this stick with my existing DDR3 1866 RAM?

Yes, if the other modules are also 1.35 V non-ECC unbuffered DDR3. The system will run all sticks at the lowest common speed and timing.

Is this the correct replacement for Micron MT8KTF51264AZ-1G9?

The module matches the Micron part on capacity, speed, voltage, pin count and unbuffered non-ECC design, making it a direct replacement.
