ASUS Desktop RAM Upgrade Instructions
Step 1: Power Down and Unplug
Shut down your ASUS desktop completely. Unplug the power cable from the rear. Wait 30 seconds for residual power to discharge.
Step 2: Open the Case
Locate the side panel release. Most ASUS desktops feature a simple slide-latch or thumb screw. Gently pull the panel toward you to open. Some ROG models have tempered glass panels that require careful handling.
Step 3: Locate RAM Slots
RAM slots are positioned vertically near the CPU, typically color-coded (blue for DDR4/DDR5). Note the position of any existing RAM modules.
Step 4: Remove Old RAM (If Replacing)
Press the release clips on both ends of the RAM module outward. The module will pop up at approximately 45 degrees. Carefully pull it out.
Step 5: Install New RAM
Align the notch on the bottom of the new RAM with the key in the slot. Insert at approximately 45 degrees, then press firmly until both clips snap into place with an audible click.
Step 6: Close and Power On
Replace the side panel and secure it. Reconnect the power cable, press the power button, and allow Windows to boot normally. The new RAM should be automatically recognized.
ASUS Desktop SSD Upgrade Guide
All modern ASUS desktops (2018+) feature M.2 NVMe SSD slots. Most models have 2–4 slots, with faster PCIe 4.0 or 5.0 support.
Locating Your M.2 Slot
Open the case and look for the M.2 slot(s) on the motherboard. They are typically labeled “M.2_1”, “M.2_2”, etc., and located near the chipset. Some slots may be covered with a heatspreader.
Installation Steps
- Power off completely and disconnect the power cable.
- Open the case and locate an available M.2 slot.
- Remove any heatspreader or thermal pad if present.
- If a screw is present in the standoff, remove it and set it aside.
- Insert your NVMe SSD at a 30-degree angle into the slot.
- Press down gently and secure with the screw.
- Close the case, reconnect power, and boot into BIOS (F2 or Del) to verify the drive is detected.
