OVERCLOCKING - PERFORMING PERFORMANCE ANALYSIS

WHAT IS OVERCLOCKING ?

Overclocking is the process of increasing the CPU/RAM/GPU frequency or clock rate. Hence the system or component works faster than the manufacture’s clock rate.
Computer components that may be overclocked include processors (CPU), video cards, motherboard chipsets, and RAM.

WHY OVERCLOCKING?

The purpose of overclocking is to increase the operating speed of given hardware.

ADVANTAGES

1) With increased electrical power consumption, it allows higher performance in

* Encoding
* Video editing applications
* Games/Game Developing
* System Services

at no additional expense.

2) SAVE MONEY - One can purchase a lower performance, cheaper component and overclock it to the clock rate of a more expensive component.

3) OLDER EQUIPMENTS - The life of older equipment in the system can be extended by overclocking.

4) BENEFICIAL TO OTHER COMPONENTS - In some instances small overclocking of a component can help realize the full potential of another component to a percentage greater than at which
hardware is clocked.

DISADVANTAGES

1) The main risks involved with Overclocking are:
* Creating system instability
* Overheating
* Damaging your hardware.

2) In overclocking a system, there is an increase in the voltage required for each piece of hardware being overclocked. Damage occurs when the voltage count is raised to an unsafe system level.

3) NO WARRANTY - Warranties may be voided by overclocking.

4) INCREASE IN TEMPERATURE - Increased clock rates and voltages increase power consumption, increasing heat production quadratically. Other components of the system may be adversely
affected due to increase in temperature due to excess heat.

5) DAMAGES CHIPS - Excessive voltages or improper cooling may instantaneously cause chip temperatures to rise, which causes the chip to be damaged or destroyed.

6) An overclocked computer which works correctly may malfunction at future configuration or changes.
For example, Windows may appear to work with no problems, but when it is re-installed or upgraded, error messages may be received such as a “file copy error" during Windows Setup.

7) HIGH NOISE - High-performance fans used for the required cooling of an overclocked machine can be noisy, producing 50-60 dB or more of noise.

TOOLS FOR OVERCLOCKING

1) EVGA PRECISIONX 4.6.1

STEPS TO OVERCLOCK

1) MSI AFTERBURN

STEP 1: Install the tool from the link given.
STEP 2: Start up the program.

STEP 3: Slider under "Core Clock" indicates the the clock speed of the processor and "Memory Clock" indicates the clock speed of RAM. "Core Voltage" indicates voltage supplied and "Fan Speed" can be increased to cool faster. Drag the slider as desired.

2) EVGA PRECISION

STEP 1: Install the software and open.
STEP 2: "GPU Clock Offset" determines the clock frequency of the GPU and "Mem Clock Offset" indicates clock speed of your RAM.

STEP 3: Drag the sliders as desired.

3) OVERCLOCKING THROUGH BIOS

PERFORMANCE ANALYSIS

In the benchmark analysis the tool used is 3D MARK 11. The video displayed during analysis is rendered by the PC. The higher the processing speed, the faster the video renders and the more the FPS (Frame Per Second) obtained. Higher FPS indicates a better performance.

BENCHMARKING: BEFORE OVERCLOCKING

Before overclocking the FPS was around 2.5 FPS indicating the default performance.

BENCHMARKING: AFTER OVERCLOCKING

After overclocking,the FPS increased dramatically to around 6.5 FPS.

GAMING ANALYSIS

For games, GPU matters more than CPU as is clearly indicated by the following videos. A smoother gameplay indicates better performance.
