A-Tech 16GB DDR4 3200 Desktop RAM

Desktop DDR4 Upgrade

The A-Tech module delivers 16 GB of DDR4 memory at 3200 MHz, matching the PC4-25600 standard. It uses a 288-pin DIMM form factor and runs at 1.20 V without ECC or registered buffering. The stick is validated as a direct replacement for the Samsung M378A2G43AB3-CWE part number. Builders expanding a desktop platform that accepts DDR4 UDIMMs can install this single module to add capacity.

Sustained Load Behaviour

Under continuous workloads the module maintains its rated 3200 MHz frequency at the standard 1.20 V. Quality-assurance testing verifies stable operation during extended multitasking and heavy memory throughput. The unbuffered design keeps latency low while the single-rank layout helps the memory controller manage timing without additional electrical load. Thermal output remains consistent with typical DDR4 DIMMs operating within JEDEC voltage limits.

DDR4 Interface Limits

The DDR4 interface tops out at the 3200 MT/s data rate this module provides, so bandwidth cannot exceed the PC4-25600 ceiling without moving to a newer memory generation. Maximum density per DIMM is constrained by the DDR4 standard, limiting future single-slot upgrades beyond 16 GB on this platform. Voltage is fixed at 1.20 V, preventing overclocking headroom that higher-voltage kits might offer. Compatibility depends on the motherboard's qualified vendor list for DDR4 UDIMMs.
