Let’s put forward the following hypothesis: overclocking equipment (in our case, processor, graphics card, RAM) significantly increases the performance of a personal computer. To test this hypothesis, we will conduct the following experiments: first with the central processor, and then with RAM and a video card.
Overclocking of the CPU took place by increasing the frequency of the system bus, a consequence of the final clock frequency, and then a stability test was run. When passing the test, the frequency was also increased and tested again. If the test was not passed, the voltage increased. This procedure was repeated until the highest and most stable frequency was detected with a limited voltage increase.
The increase in the frequency of RAM operation occurred for each platform in its own way (AMD, Intel). In all cases, they increased the throughput and reduced the latency of the system access to memory.
Extreme overclocking of the video card, previously remade, occurred by software.
First, we found out, independently of each other, the maximum frequencies of both the GPU and the onboard memory. We found out which part brings the maximum increase, took advantage of it.
The analysis shows that as a result of overclocking the processor, in synthetic tests, the computational properties have more than doubled, and bypassed the expensive processor model from the same line.
After increasing the memory frequency, the overall throughput increased (copying to memory, copying inside memory, reading from memory), and memory access delays decreased.
After the redesign of the graphics card, the hidden capabilities of the GPU became available, the performance increased to a faster and more expensive level.
Thus, thanks to the overclocking available to each user, we have received positive results. Despite this, there are still some controversial points. Consider them: 1) the service life of the chips after overclocking is reduced by 2-3 times and the manufacturer’s warranty may be lost. The average duration of operation of any chip is 15 years, but after 5 years, not only will the price of them fall, but also the performance will not meet the user’s needs. 2) After overclocking, heat generation increases – this can be corrected by improving cooling or by not increasing the voltage much during overclocking. In addition, there are extreme types of cooling, expensive and silent. 3) The equipment may burn. Combustion occurs when the maximum temperature is exceeded.
So, our assumption is confirmed by the fact that a successful overclocking in some cases is equal to an upgrade (upgrade) – the purchase of new equipment and thereby saving money.
In conclusion, I would like to say that overclocking is (, provided that this should be approached on the principle of “do no harm”. Try, accelerate, but do not follow the excitement – not everything can be dispersed or redone. Be aware of new technologies, developments, novelties. Correctly compare the performance of different firms.
And we will always remember that “A computing machine is valuable only as much as the person using it is valuable,” Norbert Wiener said half a century ago.
