Open the ClockGen utility again and attempt to increase the clock speed and voltage in one-click increments. If the computer does not crash or freeze, the overclock was successful.ĩ. Use the computer as you normally would for a few minutes. This increases the clock speed, voltage and bus speed of the memory in the 3100's CPU just slightly.Ĩ. Click the top right-arrow button under the clock icons once. In the Clock Generator Setup drop-down list, select "ICS 950405" and click "Read Clocks." A new window appears and displays the clock speed settings for your Dimension 3100 computer.ħ.
Follow the prompts to install the ClockGen utility on your computer. Right-click the "Start" button and click "Open Windows Explorer." Browse to the file you downloaded from the website and double-click it. Save the file to a folder on your computer.ĥ. Navigate to the website and download the ClockGen application. Ensure that the "Hyperthreading" value is set to "Enabled." If disabled, press the "+" key to change it to "Enabled." Press the "Esc" key to return to the main menu.Ĥ. Press the down-arrow key to scroll to the "Hyperthreading" value and press "Enter."ģ. Press the right-arrow key to scroll to the "Performance" menu option and press the "Enter" key. As soon as you see the Dell logo screen, press the "F2" key immediately. Shut down your Dimension 3100 and restart it.
By tweaking these values with a third-party application, you can improve the performance of a Dimension 3100 slightly.ġ. Nevertheless, the Dimension 3100 does support slight clock speed and voltage increases. However, the older architecture in the 3 GHz Pentium 4 630, along with low-end integrated graphics and sound, makes the 3100 lag a bit in some high-end 3D games. With its Pentium 4 630 processor, 512MB of RAM and a 160 GB hard drive, the Dimension 3100 performs relatively well with most business and productivity applications. Dell released the Dimension 3100 in late 2005 and marketed it as a high-end system at a budget price.
