Hi! You have a total of 8 GB of RAM installed. Since your PC is prebuilt, the exact details might vary, but you mentioned two 4 GB DDR3 modules at 1600 MHz from Kingston. Your motherboard has four slots, and the sticks aren’t close together, suggesting dual-channel configuration.
You can either purchase one additional 8 GB stick (same type) or buy another set of two 4 GB sticks if you prefer. Either option should work depending on availability and your needs.
