Can You Replace the RAM in a Pre-Built PC?

When you purchase a pre-built PC with a standard chassis and motherboard, there is a very high chance you can upgrade various components. These upgrades typically include RAM, GPUs, and storage devices, allowing you to tailor your system to your specific needs. However, if the chassis, motherboard, or other components are proprietary, your upgrade options may be more limited.

My Recent Experience with RAM Upgrades

Recently, I purchased a HP Pavilion Gaming PC featuring an Intel i5-9400 processor running at 2.9GHz with 8GB of DDR4 RAM and a GeForce RTX 1660Ti GPU. I wondered if it would be a good idea to upgrade the RAM to 16GB, primarily due to my observations within Windows Task Manager. My current RAM usage was already maxed out at 85-95% whenever I played games, which made me concerned about potential long-term issues and whether my PC would still boot after the upgrade. Additionally, I found that the motherboard inside the PC is an 843B model.

Reusability of RAM in Pre-Built PCs

Contrary to what some might think, a pre-built PC does not always mean that the RAM is non-replaceable. In my experience, I recently bought an HP laptop that was low-spec, but the previous owner had removed the RAM, and I picked it up for a fraction of its intended value. By replacing the RAM SoDIMM and M.2 SATA SSD, along with adding an external AC adapter, I was able to restore the laptop to its full potential. However, some pre-built systems do not offer the same flexibility, as there are instances where even laptops and slimline PCs might have RAM soldered directly to the motherboard, rendering it unreplaceable.

General Guidelines for Upgrading RAM in Pre-Built PCs

In most cases, RAM in a pre-built PC is designed to be easily replaceable. The main exception to this is when the RAM is permanently bonded to the motherboard, often found in laptops and lower-end slimline PCs. Significant variations in form factors and socket types can make it challenging to upgrade, especially with more sophisticated systems.

For example, I had a PC that came with 2GB of RAM in a single SODIMM DDR3 module. The motherboard had two RAM slots, allowing me to add another 2GB module to double the total capacity. This setup also supported dual channel RAM, which meant that two 2GB modules performed better than a single 4GB module. Most PCs are configured similarly, with the motherboard manual providing details about the system's configuration.

Checking and Upgrading RAM

To determine if you can upgrade the RAM in your pre-built PC, refer to the vendor's website or use online tools available for analyzing your PC's hardware. You can often enter your PC's make and model into these websites to find upgrading options. Ensure that the new RAM module matches the type your motherboard supports (e.g., SODIMM DDR4) and that it meets the motherboard's specific speed requirements.

While it is possible to have two RAM modules with different speeds, the motherboard will operate the faster one at the speed of the slower module. Therefore, it's crucial to verify that the new RAM module matches the manufacturer's specifications to ensure optimal performance.

Conclusion

Overall, it is often possible to replace the RAM in a pre-built PC. Ensuring compatibility with your motherboard and following the guidelines mentioned above can help you achieve a smoother upgrade process. Whether you're looking to enhance your gaming performance or improve general system responsiveness, upgrading your RAM can make a significant difference.
