RAM is used to store data that the CPU needs to access quickly. More RAM allows your system to run more applications simultaneously and handle larger datasets without slowing down. When selecting RAM, you'll want to consider factors such as capacity, speed, and latency. Capacity refers to the amount of RAM, typically measured in gigabytes (GB). Speed refers to the data transfer rate, measured in megahertz (MHz). Latency refers to the delay between when a request is made and when the data is available, measured in nanoseconds (ns).

For most gaming PCs, 16GB of RAM is sufficient, but 32GB is recommended for more demanding games and applications. Aim for RAM with a speed of at least 3200MHz, but faster speeds like 3600MHz or 4000MHz can provide a slight performance boost. Lower latency RAM is generally better, but the difference is often negligible in real-world gaming scenarios. Ensure the RAM is compatible with your motherboard's specifications, including the type of RAM (DDR4 or DDR5) and the maximum supported speed and capacity. Consider purchasing a RAM kit with multiple modules (e.g., 2x8GB or 2x16GB) to take advantage of dual-channel memory, which can improve performance. Always check the motherboard's QVL (Qualified Vendor List) to ensure the RAM you choose has been tested and verified to work with the motherboard.

Storage (SSD or NVMe)

Storage devices are used to store your operating system, games, and other files. Solid-state drives (SSDs) have largely replaced traditional hard disk drives (HDDs) as the primary storage device in gaming PCs due to their much faster read and write speeds. NVMe (Non-Volatile Memory Express) SSDs offer even faster speeds than SATA SSDs, making them ideal for loading games and applications quickly. When selecting a storage device, you'll want to consider factors such as capacity, speed, and interface.

For a gaming PC, a 500GB or 1TB NVMe SSD is recommended for the operating system and frequently played games. A secondary, larger capacity HDD can be used for storing less frequently accessed files, such as movies, music, and documents. NVMe SSDs connect directly to the motherboard via the M.2 slot, while SATA SSDs connect via SATA cables. Ensure your motherboard has an M.2 slot that supports NVMe SSDs if you plan on using one. Look for SSDs with high read and write speeds to minimize loading times. Consider the lifespan of the SSD, which is typically measured in terabytes written (TBW).
