Interview With an Overclocker
- What is overclocking?
- Overclocking is running your CPU at a higher frequency than normal factory specs permit.
- Can a CPU be destroyed by overclocking?
- Yes. If the voltage is set too high, the CPU can be damaged.
- How does overclocking effect the CPU's warranty?
- Overclocking is at the owner's risk and voids the factory warranty.
- Can overclocking be done without destroying the CPU?
- How can Overclocking be achieved?
- By changing the FSB (front side bus) and the voltage of the motherboard's CPU settings.
- What is the FSB of the computer?
- The FSB on the computer motherboard controls the CPU and the AGP speed of the motherboard.
- How does AGP speed affect a successful overclocking?
- Your AGP speed is two thirds (2/3) the speed of your front side bus. So, with the FSB set to 100MHz the AGP clock is 66MHz, but at 133MHz 2/3 is 89MHz, way out of spec for most video cards.
- Can I still successfully overclock my system with the FSB set to 133MHz and the AGP at 89MHz?
- Yes. Some video cards such as the Ge-Force work just fine at these settings.
- What is the core voltage of the CPU and why would it be changed?
- The core voltage of the CPU is how much electricity is running through your CPU. Sometimes increasing it stabilizes the CPU in an overclocked state.
- What does RAM have to do with overclocking?
- A general rule of thumb is: 100MHz RAM can be clocked to 112MHz and 133MHz RAM can be clocked to 150MHz. Using quality RAM is always your best bet when overclocking.
- What is the clock speed of the CPU and its function?
- The clock speed is the fixed multiplier on your chip; 5x , 6x etc. times your FSB. This is locked by the manufacture to prevent overclocking.
- Do any CPUs work better than others in an overclocked state?
- Any CPU can be overclocked, but even numbered CPUs (4x5x6x}have the best success rate because they usually overclock to an actual CPU speed.
- Does it matter if the CPU is retail or OEM ?
- No. As long as it has a good fan and heatsink you're okay.
- What are the best motherboards for overclocking?
- Asus and Abit always make great boards for the overclocker, but any board that allows you to tweak the FSB via
the BIOS or adjustable jumpers should work fine. Just make sure it has good support.
- Are there any general guidelines to go by?
- Yes. Read and know your motherboard manual; it's your map to its settings. And always start in small steps and work your way up. Like all things, you have to walk before you can run.
- Is overclocking for everyone?
- No, but for performance-hungry enthusiasts it's the only way to fly!
