- Why overclocking usually also needs to overvoltage?
When we overclock CPU or GPU or RAM we also have to increase the voltage to achieve stable operation (provided we have adequate cooling). Why is that?
Was that kid you? Otherwise, how does your post help this thread?Keith_McClary said:A kid was shocked to learn that there was a clock to slow down our computer! Why not just let it run infinitely fast?
It's another aspect of the same limitations of the electronics.berkeman said:how does your post help this thread?
Please explain your reply in detail with technical details and reference links. Thanks.Keith_McClary said:A kid was shocked to learn that there was a clock to slow down our computer! Why not just let it run infinitely fast?
The answer to both questions is that the circuit requires a certain minimum time (which may depend on voltage) to complete a cycle.berkeman said:Please explain your reply

As explained by Tom.GDelta2 said:How this minimum time to complete a cycle can depend on voltage?
You can run a CPU at the specified clock rate reliably. You may be able to run it faster, but at some speed, voltage, and temperature, it will become unreliable.Delta2 said:How this minimum time to complete a cycle can depend on voltage?
While the temperature and voltage may change, an asynchronous CPU always runs reliably at the maximum possible speed.Delta2 said:but I don't understand why @Baluncore decided to throw in the case of asynchronous CPU. OK no clock there so not possible overclocking at least not in the traditional sense.

The power equation on page 13 shows that a 1% increase in Vdd increases power by 2%, (square), and the 1% increase in frequency makes it a 3% increase in power.alan123hk said:Unfortunately, the power loss will also greatly increase in proportion to the square of the power supply voltage.

Overclocking is the process of increasing the clock speed of a computer component, such as the CPU or GPU, beyond its factory settings. This allows the component to perform at a faster speed, potentially increasing overall system performance.
Overclocking can be safe if done properly and within certain limits. It is important to monitor the temperature and voltage levels of the component to ensure it is not being pushed too hard, which can cause damage. Additionally, overclocking may void the warranty of the component, so it is important to consider the risks before attempting it.
Overclocking can provide a significant increase in performance, allowing for faster processing speeds and improved graphics performance. This can be especially beneficial for tasks that require a lot of processing power, such as gaming or video editing.
The main risk of overclocking is potential damage to the component if it is pushed too far. This can result in reduced lifespan or complete failure of the component. Additionally, overclocking can also cause instability and crashes if not done properly, leading to data loss or system malfunctions.
Not all components can be overclocked. Generally, only CPUs, GPUs, and RAM can be overclocked. Other components, such as hard drives and power supplies, do not have adjustable clock speeds and therefore cannot be overclocked.
