Overclocking The CPU Can Boost Performance
Some of the Intel i7 line of central processing units (CPUs) are designed in a way which allows them to be overclocked resulting in a faster computing experience. Overclocking the i7 in this way does not require any modification to the chip itself and can be done solely through software means. While making a CPU run at a faster speed can make a computer faster, the CPU will generate a lot of extra heat. Some new hardware may need to be installed on the CPU to keep it cooler at hotter temperatures.
Instructions
1. Turn on your computer and hit the "ESC" key as soon as you see text on the screen or your computer manufacturer's logo to enter the BIOS.
2. Set the Intel Turbo Boost setting to "DISABLED." Leaving this on can interfere with the upcoming new voltage settings.
3. Set the BCLK to "200 Mhz." The BCLK is the Base Clock setting for the CPU. Set the QPI, or Intel QuickPath Interconnect, for "18x" and the unicore to "16x" in case your motherboard does not automatically adjust other settings to fit the BCLK. The unicore always needs to be less than the QPI.
4. Set the DRAMM frequency to "1,600 Mhz." Set it to the lower of the two settings if you don't have this option.
5. Set the CPU voltage to "1.35V." Depending on the needs of the CPU, less voltage can sometimes be used.
6. Set the CPU PPL voltage to "1.96V."
7. Set the QPI/DRAM Voltage to "1.35V." This may show up as "QPI/Memory Controller" on some BIOS settings but they are the same thing. This setting has to be changed to keep the CPU protected.
8. Set the DRAM Voltage to "1.66V." If the memory in your system is designed for 1.65V, this is an acceptable setting to use since it falls within the +/- 0.5V unicore allowed difference.
9. Enable the High Performance Event Timer (HPET) for the CPU. This will ensure the clock speeds on the i7 are kept accurate and prevent possible damage to the CPU.
10. Close the BIOS and choose "Y" to accept changes. This will reboot the computer and apply the changes made to the CPU settings.
