DDR5 32GB (16GBx2) 4800MHz (PC5-38400) 288-pin CL40 1.1V Desktop Memory 1.1V low voltage and low power consumption Uses On-Die Error Correction Code (ECC) to improve stability Power Management Integrated Circuit (PMIC) provides stable power supply for uninterrupted gameplay Note: DDR5 is not compatible with DDR3 or DDR4 With even more speed, capacity, and reliability, this DDR5 UDIMM module's cutting-edge technology brings the next level of edge to your laptop's performance. Aggressive 4800MHz frequency provides multi-core CPUs with ultimate responsiveness and power to multitask seamlessly. This DDR5 UDIMM module improves on its predecessor with on-module voltage regulation, even with the additional power. A power management integrated circuit (PMIC) reduces the burden on motherboard control and achieves a low voltage of 1.1V. This DDR5 UDIMM module features On-Die ECC (Error Correction Code), a new feature designed to correct bit errors in DRAM chips in real time. In doing so, this advanced technology automatically corrects data errors while ensuring system stability.
