16GB RAM (8x2) DDR5, clean, Mashallah, and its speed is 5600MHz from Crucial, a well-known company with reliable quality. The difference between it and 16GB RAM is that the two 8GB sticks are faster, better, and more stable in performance and usage due to dual-channel technology. The reason for selling is the need for money, and I barely use the PC, I keep it almost like decoration.
