  3. Browse to the manufacturer's site for your processor, either intel.com or amd.com. Type in the exact name of your processor into the search bar and press "Enter." Click the link to the specifications for your processor.

  4. Find the L1 and L2 Cache sections in the specifications. These are the cache levels that your CPU is supposed to have.

Software

  1. Download a software tool that will scan your computer's CPU. Some options are Cachchk7 available at developer-resource.com, CPU-Z available at CPUID.com or CHKCPU available from web.inter.nl.net.

  2. Unzip the download, if it came as a zipped file. You can tell this if the folder icon has a zipper on it. Right-click and select "Extract" and then follow the on-screen instructions to finish unzipping the download.

  3. Run CPU-Z by first installing it. Double-click "Setup.EXE" and follow the on-screen instructions. Once the installation is complete, click "Start" and then type "CPU-Z" and press "Enter" to run the program. The L1 and L2 Cache information is located in the Cache section.

  4. Run Cachchk7 by by clicking "Start" and then typing "CMD" and pressing "Enter." Type "cd [folder location]" where the folder location is the place on your hard drive where you downloaded Cachchk7, for example: "C:\Cachchk7\" and press "Enter." Type "Cachechk.EXE" and press "Enter." Wait for the check to complete and then you will see the L1 and L2 Cache levels displayed.

  5. Run ChkCPU by clicking "Start" and then typing "CMD" and pressing "Enter." Type "cd [folder location]" where the folder location is the place on your hard drive where you downloaded ChkCPU, for example: "C:\CHKCPU\" and then press "Enter." Type "CHKCPU" and press "Enter" to run the scan. The L1 and L2 Caches will be displayed.
