System Overclock

What is Overclocking?

Within a system, all components are manufactured with default computing speeds (clock) and power consumption levels. Overclocking is a customization of clock and power level set by the user. Components that are frequently used in overclocking include the CPU (Central Processing Unit), RAM (Random Access Memory), and GPU (Graphics Processing Unit). Overclocking allows an increase in performance, but may lead to a decrease in the lifespan of components.

 

CPU Overclocking

CPU Overclocking is when a user adjusts the clock speed and power level of a CPU. It is typically configured within the mainboard’s BIOS. The default clock speed and power level differ from one lineup to the other. Therefore, it would be wise to refer to successful overclocking attempts made by members of H/W communities. The typical overclocking steps are as follows: (1) Power level adjustment -> (2) Clock speed adjustment -> (3) Power level stabilization -> (4) System stabilization.

(1) Power Level Adjustment
– To find the CPU’s maximum clock, adjust the power level amply.
– Adjust the increase depending on the manufacturer: Intel – 1.3V; AMD – 1.35V

(2) Clock Speed Adjustment
– Increase by multiples of 5 from the default settings (it may differ depending on the manufacturer and/or the model)
– Boot the system -> Lower speed when booting fails
– Repeat the steps above to find out the maximum speed

(3) Power Level Stabilization
– Decrease the power level by 1 step (0.005 ~ 0.001) from the setting in step (1)
– Boot the system -> Decrease the power level by another 1 step if booting succeeds.
– Repeat the steps above to find out the minimum power level

(4) System Stabilization
– With (2) and (3) set, use stress test tools such as LinX to test how a processor copes under a heavy load
– If a BSoD occurs, increase the power level by 1 step or decrease the clock speed by 1 level
– Check the CPU’s temperature with an HW monitoring tool. If it seems to high, decrease the clock speed.
– If the system seems stable, conduct final tests with various programs

 

If you have completed (4), then it is safe to say that the CPU overclocking has succeeded. There is also a way to adjust the clock speed without manipulating the power level. Follow the steps listed above with the exception of (3). It is harder to achieve maximum clock speeds because of the lack of power, but it is still relatively safe.

I would definitely recommend you to use a 3rd party CPU cooler. You will be seeing a significantly higher cooling effect compared to the default cooler.

 

RAM Overclocking (DDR 4 base)

The process of overclocking RAM is also conducted within the BIOS. As I have mentioned above, I would recommend you to visit an H/W community for successful adjustment records. The typical RAM overclocking process is as follows: (1) Pre-adjustment -> (2) Clock adjustment -> (3) Timing adjustment -> (4) System stabilization.

 

(1) Pre-adjustment
– Power level: 1.35V; Clock speed: 3200MHz; Timing: 18-18-18-18-38 1T

(2) Clock adjustment
– Boot the system -> If booting fails, decrease the clock speed by 100MHz
– Repeat the steps above to find out the maximum clock speed

(3) Timing Adjustment
– Decrease the timing by 1 level from the settings in (1): (18-18-18-18-38 -> 17-18-18-18-38 -> 17-17-17-18-38…)
– Repeat the steps above to find out the minimum timing

(4) System Stabilization
– With (2) and (3) set, boot the system and use tm5(TestMem5) to detect memory errors
– If an error is detected, decrease clock speed and/or increase timing
– Conduct stress tests with the LinX tool
– If the system seems stable, conduct final tests with various programs

 

 

GPU Overclocking

GPU overclocking was initially popular within gaming communities that required high system requirements. Now, miners who use the PoW method make up most of the demand. GPU overclocking is done by using tools provided by graphic card manufacturers. Afterburner, a free tool provided by MSI, is the most frequently used tool.

 

Overclocking tools provided by manufacturers have user-friendly UI, making it easy to customize. The typical GPU overclocking process is as follows: (1) GPU/Memory clock adjustment -> (2) GPU power level adjustment -> (3) Benchmarking tool test -> (4) System stabilization

 

(1) GPU/Memory clock adjustment
– Adjust GPU, Memory rates within the overclocking tool
– The overclocking tool reflects changes immediately. Find the optimal rate as changes are made.

(2) GPU power level adjustment
– If the system stalls during (1), increase the power level by small percentages
– If the power level is too high, the graphic card’s power source may go through overload. Find the minimum level.

 

(3) Benchmarking tool test
– Conduct tests using benchmarking tools such as 3DMark
– Decrease the levels set in (1) if the system shuts down and/or the GPU’s temperature is too high
– If the system seems stable, conduct final tests with various programs
– Using Ethereum’s mining program may be a good testing tool since the PoW mining algorithm depends heavily on a GPU’s memory clock.
