4GB DDR4 2400MHz Desktop Module

This single 4GB DDR4 module runs at 2400MHz with CL17 latency and 1.2V operation. It uses a 288-pin unbuffered DIMM form factor built with major brand chips. The kit is designed as a direct replacement for Dell part numbers A9321910 and SNPGTWW1C/4G. It targets desktop users who need a straightforward capacity increase for everyday workloads.

Thermals and Power in Daily Use

Standard 1.2V DDR4 voltage keeps power draw low during typical desktop tasks. The unbuffered design adds no extra electrical load beyond the memory chips themselves. No active cooling is required and the module runs silently inside a normal case airflow path. Heat output stays within normal DDR4 limits for a 4GB stick at this frequency.

What the Bundle Changes

The package contains only the memory module itself with no extra cables, brackets or software utilities. Installation is a simple DIMM slot insertion followed by an automatic BIOS detection at 2400MHz. No driver downloads or configuration tools are needed to enable the rated speed. The lifetime warranty and US-based technical support cover the module after installation.
