Upgrade your hardware

Hardware upgrades are often the most effective solution to improve Excel’s performance on Windows 10. Here are some of the most common hardware upgrades that can make a significant difference in Excel’s speed:

Add More RAM:


Excel can consume a lot of memory, especially when working with large datasets or complex formulas. Adding more RAM to your computer can help reduce the amount of time Excel spends swapping data to the hard drive and improve overall performance. Ideally, you should have at least 8 GB of RAM for basic Excel usage, and 16 GB or more if you work with large datasets frequently.

Use a Solid-State Drive (SSD):


Traditional hard drives (HDD) can be a bottleneck when it comes to Excel’s performance, as they have slower read and write speeds compared to SSDs. Upgrading to an SSD can help reduce the time it takes for Excel to open and save files, as well as improve the overall responsiveness of your computer. If you are on a tight budget, consider getting a smaller SSD (such as 256 GB) to install your operating system and programs, while using an external hard drive for storing files.

Upgrade to a Faster CPU:


Excel’s calculation speed heavily relies on your computer’s CPU. If you frequently work with large datasets or complex formulas, upgrading to a faster CPU can significantly improve Excel’s performance. However, CPU upgrades can be expensive and may require replacing other components, such as the motherboard or RAM. Make sure to do your research and consult with a professional before upgrading your CPU.

It’s worth noting that hardware upgrades can be costly, and may not always be necessary depending on your Excel usage. If you are not sure which hardware upgrade would be the most beneficial for you, consider monitoring your computer’s performance using the Windows Task Manager and identifying which component is the bottleneck. In some cases, optimizing Excel settings or managing your data more efficiently may be enough to improve its performance.
