Hi @Archy1903 

Welcome to the HP Support Community!

Thanks for posting your query! We're here to help you get back up and running.

Upgrading your HP 40L Desktop PC GT21-1000i to 32GB RAM is a fantastic way to boost performance—especially with that powerhouse combo of the i7-13700K and RTX 3070 Ti. Let’s walk through it step by step with care and clarity:

🧠 Step 1: Check Current Configuration

Your system likely has 2×4GB or 1×8GB DDR5 RAM installed. This model supports DDR5 UDIMM modules and has 4 DIMM slots, with a maximum capacity of 128GB.

 

🛒 Step 2: Choose Compatible RAM

To ensure smooth operation, HP recommends using memory that matches the existing specs. Based on your system, here are some compatible options:

• Kingston FURY Beast DDR5 5200MT/s CL40 UDIMM
• Crucial Pro DDR5 6000 or 6400 UDIMM (CL36–40)

For 32GB, you can go with:

• 2×16GB DDR5 UDIMM modules (preferably same brand and speed for best compatibility)

 

🧰 Step 3: Prepare for Installation

1. Shut down your PC and unplug all cables.
2. Press and hold the power button for 5 seconds to discharge residual power.
3. Open the side panel of your desktop (usually tool-less on the 40L).
4. Ground yourself to avoid static discharge.

🔧 Step 4: Install the RAM

1. Locate the DIMM slots on the motherboard.
2. If you're replacing existing modules, gently release the clips and remove them.
3. Insert the new RAM sticks into slots 2 and 4 (or follow the motherboard’s dual-channel layout).
4. Press firmly until the clips snap into place.

 

🖥️ Step 5: Boot and Verify

1. Power on your PC.
2. Enter BIOS (tap F10 during startup) to confirm the system detects 32GB.
3. Alternatively, check in Task Manager > Performance > Memory.

If the system doesn’t boot or shows incorrect memory, reseat the modules or try different slots. And if you’ve enabled RAM overclocking in OMEN Gaming Hub, it’s best to disable it before the upgrade to avoid compatibility hiccups.

Let me know if you’d like help picking a specific RAM kit or checking BIOS settings—I’m right here with you!

Amazon sells Kingston FURY Beast Black 32GB (2x16GB) 5200MT/s DDR5 CL36 DIMM are these OK

@Archy1903 

Yes, that Kingston FURY Beast Black 32GB (2×16GB) 5200MT/s DDR5 CL36 DIMM kit is a solid choice for your HP 40L GT21-1000i desktop. It’s fully compatible with your system’s DDR5 UDIMM slots and matches the supported speed and voltage specs.

A few quick tips before you install:

• Make sure both sticks are from the same kit (which they are in this case) to ensure dual-channel performance.
• If your system originally came with 8GB (likely 1×8GB), remove that module before installing the new pair.
• After installation, check BIOS or Task Manager to confirm the full 32GB is recognized.
