4GB DDR3 1600 Desktop Upgrade

This 4GB DDR3 1600 module upgrades a desktop that uses 240-pin unbuffered DIMMs. It runs at the standard 1.5V DDR3 voltage and carries a PC3-12800 rating. The single-rank 1Rx8 organisation keeps electrical loading light on the memory controller. Builders who want ECC error correction or registered buffering cannot use this module.

Replaces Micron MT8JTF51264AZ-1G6E1

The stick is a direct replacement for Micron part numbers MT8JTF51264AZ-1G6 and MT8JTF51264AZ-1G6E1. Swapping an older or failed 4GB DDR3 DIMM for this unit restores the original capacity and 1600 MT/s data rate. The jump is worth it when the existing module has failed, runs at a lower speed, or when a vacant slot is available for a simple capacity increase.

Steady 1600 MT/s under load

Rated at 1600 MT/s and tested at that frequency, the module maintains its data rate during extended workloads rather than only in short bursts. Standard 1.5V operation avoids the extra heat that higher-voltage kits produce during sustained use. Unbuffered signalling adds no latency penalty, so throughput stays consistent across long rendering, compilation or virtualisation sessions.

Questions about this item

Will this module fit my motherboard's 240-pin DDR3 slots?

Yes, it is a standard 240-pin DDR3 DIMM designed for desktop boards that accept unbuffered, non-ECC memory at 1.5 V.

Can I mix this 4 GB stick with my existing 1600 MHz DDR3 RAM?

Mixing works best when speed, voltage and timing match; this module runs at 1600 MHz and 1.50 V, so it will pair cleanly with identical spec kits.

Is this a direct replacement for Micron part MT8JTF51264AZ-1G6E1?

The supplier lists it as a compatible replacement for both MT8JTF51264AZ-1G6 and MT8JTF51264AZ-1G6E1 part numbers.
