Key notes

  • If you’re noticing FPS drops after upgrading your RAM, they are either not compatible or not well plugged in.
  • An outdated GPU driver or a corrupted system file may also cause this problem.
  • Upgrading the original HDD to a faster SSD should prove a quite cost-effective way to fix the FPS drop issue.

FPS drops are one of the major game issues affecting the gaming experience for game enthusiasts. A recent report from some of our readers is that they encounter an FPS drop after RAM upgrade.

This can be quite frustrating as FPS drops can affect even games with low specs. Regardless, we have gathered some potential fixes for this error in this article.

Why did FPS drop after RAM upgrade?

FPS drops in games are usually associated with outdated or corrupted drivers. However, we have outlined some other factors that may contribute to the FPS drop after a RAM upgrade:

  • RAM installation – The RAM modules were either not properly installed on the motherboard or incompatible.
  • Different RAM capacities – When using the RAM in Dual channel mode, they must be the same capacity. For instance, if you were using a 2 x 8 GB RAM Dual channel configuration, replacing one of them with a 16 GB module will disable the Dual channel mode and cause the FPS drop.
  • Issues with Graphics driver – One of the major reasons behind several FPS drop issues are due to an old or corrupted graphics driver.
  • Windows update issues – Another possible reason for the FPS drop after the RAM upgrade is a problematic Windows update.
  • Inadequate cooling system – The components’ performance tends to decline when they start to overheat due to insufficient ventilation. Check our guide for the best laptop cooling software.

Irrespective of the causes, let’s proceed to how you can fix this problem.

What can I do if FPS drops after RAM upgrade?

Before applying any tweaks, you should try some of the preliminary checks below:

Having confirmed the above checks, and if you still require further assistance, you can explore the solutions provided below.

1. Scan your RAM for errors

  1. Press the Windows key + R to start the Run console, type mdsched.exe and hit Enter or click OK.
  2. Now, click on Restart now and check for problems.
  3. After restarting, the tool is going to perform a scan of your memory and it will provide a report with any errors if any are found.

If there is any problem with any of your RAM modules, this tool will find it. Also, if it’s possible, we recommend unplugging the modules, attaching them again carefully, and repeating the test.

2. Run an SFC (System File Checker) scan

  1. Press the Windows key, type cmd in the search box, and click Run as administrator.
  2. In the CMD window, type the following command in the text field and press Enter: sfc /scannow
  3. The scanning process may take some time, so wait till the verification is complete and restart your PC.

The SFC scan is one of the best tools to identify corrupt system files and replace them with their cached copy stored on the system. Running the scan will enable you to know the root of the problem and likely how to fix it.

If you want to try an automatic alternative to running an SFC scan, then we recommend a dedicated app to repair corrupted files on Windows.

This software is capable of replacing corrupt files automatically with healthy components from its database after a thorough scan of your operating system.

3. Update your GPU drivers

  1. Press the Windows + R keys to open the Run window, type devmgmt.msc, and press Enter.
  2. Choose Display adapters by double-clicking from the search results, then right-click on the graphics driver, and select Update driver from the context menu.
  3. Now, select Search automatically for drivers and let Windows install the best available version.
  4. Restart your computer after the updating process is complete.

As an alternative, you might get the most recent graphics driver from the manufacturer’s website, such as Intel, AMD, or Nvidia, depending on your GPU.

Instead of doing this, you can manage your graphics card driver more easily using a dedicated tool.

Ensure your system performs smoothly and avoids all GPU driver errors by using a complete driver update assistant, namely Outbyte Driver Updater, that will do the job for you. Here's how to safely update your drivers:
  1. Download and install the Outbyte Driver Updater app.
  2. Launch the software and wait for the app to detect all incompatible drivers.
  3. Now, it will show you a list of all faulty drivers to select the ones to Update or Ignore.
