Overclocking is the process of making a computer component run at a higher speed than the manufacturer specified. The CPU is one of the components of the system that is commonly overclocked. The CPU clock speed is the FSB product (Front Side Bus) speed and the CPU’s multiplier (sometimes called the clock ratio).
CPU Clock Speed = FSB Speed * CPU Multiplier
The CPU clock speed may be increased by increasing either the FSB Speed or CPU Multiplier. However, it is interesting to note that increasing the FSB speed will have a greater impact as it increases factors such as memory speed (for synchronous operation) and processor speed. The CPU multiplier is also comparatively difficult to adjust.
The following section describes how overclocking may be done with the BIOS. Enter the BIOS during system startup. Select the Bios Features Setup, CPU Soft Menu, or any other similar option and press Enter. Modify the CPU Host Bus Frequency, External Clock (PCI), or similar option. Page Down until the desired motherboard FSB speed (for example 200 MHz for processors whose FSB normally works at 166 MHz) is found. In the CPU Core section, find the Multiple Bus Frequency or Multiplier factor and modify the value of the CPU Multiplier (for example 11x may be changed to 13x). Now save the changes to the CMOS and exit. It is generally advisable to change the parameters in steps. For example, increase the FSB speed by a few MHz and check whether the system boots. If the computer boots, increase the speed further and check again. Repeat until the highest setting with which the computer will boot up is obtained. Now test the OS with some resource hungry application (like a game) to check whether the system crashes. If it crashes, lower the FSB speed in steps to the point where the system is stable.
Overclocking results in voltage profile change within the circuitry. This can be minimized by increasing the voltages applied, but too much increase can burn up the circuitry. A bigger problem is the heat generated due to overclocking. This is tackled through the use of better CPU heatsinks and fans, heat spreaders on memory, fans on video cards, and case fans.
I have an hp dv6-3225dx and I can’t seem to overclock in bios. The bios will only let me change the date and time. I have looked over and over again and I can’t find any other options in bios. I press esc. When starting computer and then I go to bios setup( F-10). There isn’t anything I can change other than the date and time. If I’m doing something wrong please tell me. Thanks, chrisl2366
i think u mention hp is a laptop. almost all laptop are non- oc able. that mean u can’t oc on the laptops due to the poor heat dissipation of the laptop structure compared to desktops
