RAM upgrades deliver immediate performance improvements, especially when working with multiple applications simultaneously. Most systems ship with 8GB or 16GB; upgrading to 32GB or 64GB benefits professionals using resource-intensive applications like video editing, 3D modelling, and virtual machines.

Determine your current configuration by checking System Information or BIOS. Your motherboard’s manual shows exactly which slots are DIMM (standard) or SO-DIMM (laptop-style), critical for selecting the correct memory type.

SSD Upgrade Guide

Storage is often the limiting factor in system responsiveness. Adding a second M.2 NVMe SSD is typically the most straightforward upgrade, offering PCIe speeds without opening the main chassis extensively. SATA SSDs work too, but are significantly slower for sequential operations.

Check BIOS to identify existing drives and available slots. Many systems support both M.2 and 2.5-inch SATA simultaneously, letting you keep existing storage whilst adding high-speed NVMe capacity.

How to Find Your Model Number

Method 1 (Easiest): Look at the case label on the rear or side panel. The model number appears near the serial number.

Method 2 (Windows): Open System Information (Windows + Pause or Settings → System → About), look for “System Model.”

Method 3 (BIOS): Restart and enter BIOS (usually Delete or F2 during boot), where the model and motherboard information are displayed.

Method 4 (Command Line): Run wmic csproduct get name in Command Prompt for the exact system model.
