How to Scan My PC to See What PCI Slot I Have
By Chad Davis
It's important to perform a detailed analysis of your computer system before installing any new hardware components. While Windows provides basic system information, such as the Device Manager, you may need more detailed information about specific hardware slots and peripheral devices. Fortunately, there are many software applications available that can provide you with advanced hardware diagnostics and system information. After you have downloaded and installed the necessary software, you can easily identify what type of PCI slot your computer is using.
Download CPUID's PC-Wizard by clicking the "Direct Download Link" link on the CNet Download PC Wizard page (see Resources).
Open the downloaded installation file. Click "Yes" or authenticate with an administrator account if prompted by User Account Control.
Click "OK" and follow the setup wizard's instructions to install the software. Click "Finish" once the setup has completed to launch PC Wizard.
Click the "Mainboard" icon -- the second icon under Hardware which resembles a motherboard -- scroll down the Item column and then select "PCI Bus" to highlight the item.
Scroll down the content pane under the Information tab and then locate "Peripheral Type" group. The type of PCI bus will be listed next to each device under the Peripheral Type column. For example, if "PCI-Express" is listed, your PC is utilizing PCI-Express slots.
Navigate to the CNet Download AIDA64 Extreme page and then click the "Direct Download Link" to download the installation file (see Resources).
Run the downloaded software and then click "Yes" or authenticate with an administrator account when prompted by User Account Control.

Click "Computer," click "DMI" and then click "System Slots" to view the PCI slots on your PC.
Locate the value for the "Type" field to determine your PC's PCI slot type. For example "PCI-E" represents PCI-Express.
Navigate to CNet's download page for Speccy (see Resources) and then click the "Download Now - CNET Secure Download" button.
Open the setup file and follow the installation wizard's instructions to install the software. Click "Finish" to complete the installation and launch Speccy.
Click on the "Motherboard" link located in the navigation pane. The PCI slots on your PC will display under the PCI Data group. The specific type of PCI slot is listed next to "Slot Type" with each PCI entry. For example, "Slot Type - PCI-Express" indicates that your computer uses PCI-Express slots.
Always consult your manufacturer's documentation before installing new hardware components.
