CPU-Z, although an extremely useful tool, often runs into issues. One of the common problems is CPU-Z not showing RAM or displaying a limited number of slots. Also, there are times when CPU-Z detects RAM, but BIOS and Windows don’t!

TheMemorytab in CPU-Z is greyed out usually due to missing permissions, misconfigured BIOS settings, a bug in the installed version of the tool, or incompatible or damaged memory modules.

Before you move to the solutions, reboot the PC, install all pending Windows updates, or if the problem started recently,uninstall the Windows updatedownloaded around the same time!

What can I do if CPU-Z is not showing RAM or SPD?

1. Run CPU-Z as an administrator

In 3 out of 5 cases when CPU-Z is not showing RAM or theMemorytab is blank, it’s the missing permissions to blame. Andrunning the tool with administrative privilegesfixes things in no time!

2. Check the SPD tab

Sometimes, theMemorytab in CPU-Z is greyed out, but the SPD tab lists the information. So, if you just want a brief overview of the connected RAM modules, simply go to theSPDtab, navigate through the different slots, and gather all the information you need.

Remember, this is not a solution but a workaround that allows you to access the RAM-related information quickly without worrying about fixing CPU-Z.

3. Enable XMP in BIOS

If CPU-Z is not showing correct RAM speed or the one it displays is lower than what was advertised for the memory module, you must enable XMP(Extreme Memory Profile)in BIOS. Switching to XMP also fixes things whenRAM is not running at full speed.

4. Reinstall another version of CPU-Z

CPU-Z often leaves behind some files after a quick removal, which might trigger conflicts during reinstallation. That’s why experts recommend using atop-rated uninstaller softwareto delete all leftover files, app cache, and Registry entries.

5. Reconnect the memory modules

Often, when CPU-Z is not showing the correct RAM size or doesn’t display anything at all, it’s likely that the RAM modules are not connected properly and need to be reseated.

Simply disconnect each one of the modules and then seat them in the respective slots, as specified by the system manufacturer. You can refer to the computer’s manual for the ideal arrangement of the RAM modules.

6. Look for compatibility issues

If CPU-Z shows more RAM than Windows, it’s because the connected modules are not compatible with your PC. The RAM size displayed in CPU-Z is the total connected, whileTask ManagerandBIOSlist the RAM size currently in use(Total RAM – Incompatible RAM = Usable RAM).

So, that’s why you have different RAM sizes in CPU-Z andTask Manager/BIOS!

The best solution in this case is to check the manufacturer’s official website, identify the RAM type compatible with your PC, and get more of the same sticks.

7. Check the memory sticks for damage

In case CPU-Z detects RAM but BIOS and Windows don’t, check the modules for damage and scratches. A damaged, unreadable module is most likely to trigger this problem.

If you have spare RAM sticks (compatible with the PC), connect them and check for improvements. Because if it works now, the earlier modules were damaged and have to be replaced.

With these methods, you can fix things when CPU-Z is not showing RAM or displays the incorrect memory size and speed. In my experience, it’s usually the missing permissions or the disabled XMP profile that are to blame for such inconsistencies.
