7. To gain access to the second CPU voltage regulator module (VRM) socket on the system board, move aside all power supply cables as necessary. Disconnect cables to the drives only if necessary. 8. Install the VRM supplied with the microprocessor. See "Identifying parts on the system board" on page 61 for the location of the second CPU VRM socket. 9. Replace the cover. See "Replacing the cover and connecting the cables" on page 83. Notes: 1. If you add a second microprocessor that runs at a different speed than the primary microprocessor, both will run at the speed of the slower microprocessor. 2. You might need to download and install the current Flash Update program after installing the second microprocessor. See "Updating system programs" on page 28 for more information. What to do next: To work with another option, go to the appropriate section. To complete the installation, go to "Completing the installation" on page 84. Installing a security U-bolt To help prevent hardware theft, you can use the cover lock and add a security U-bolt and cable to your computer. After you add the security cable, make sure that it does not interfere with other cables that are connected to the computer. Before you begin: Obtain the following: - A 19-mm (3/4 in.) U-bolt and threaded nuts that fit the U-bolt - A security cable - A lock, such as a combination lock or padlock - An appropriately sized or adjustable wrench - A small, flat-blade screwdriver Turn off the computer and all other connected devices.
