A-Tech 4GB DDR3 1600 PC3-12800 240-Pin 1Rx8 Desktop RAM for Micron MT8JTF51264AZ-1G6E1

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.
