The CT4K16G4VFS424A from Crucial is a specialized DDR4 2400 memory module kit tailored for scenarios where space and thermal management are crucial. This kit is comprised of four very low-profile (VLP) 16GB modules, adding up to 64GB of ECC Reg/RDIMM memory, perfectly suited for small form factor (SFF) servers and computing devices. Operating at PC4-19200 specifications with 288 pins, these modules ensure compatibility with a broad range of DDR4 systems while offering the performance benefits typical of DDR4 technology, such as higher transfer rates and improved energy efficiency compared to its predecessors. The ECC functionality ensures that data corruption is detected and corrected in real-time, vital for maintaining system stability and data integrity in critical applications. The VLP design of the modules significantly aids in improved airflow within compact systems, helping to reduce thermal buildup and allowing for more efficient cooling. Tailored for systems with limited space but no compromise on performance and reliability, the CT4K16G4VFS424A kit is an optimal choice for compact servers, networking equipment, and other space-constrained applications.
