Overclocking i5-750 can improve the performance of a personal computer. Although this microprocessor is outdated at the moment, but its technical parameters still allow you to solve any problems. It is overclocking and characteristics of this chip that this material is dedicated to.
Equipment. Recommendations on the selection of computer system components
The delivery list of this CPU model includes the following components:
- Microprocessor.
- Cooling system.
- Thermal grease.
- Sticker with the logo of the family of ranks.
- Warranty card.
- Transport box, which is made of transparent, shockproof plastic.
- A small user guide.
Acceleration of the i5-750 in combination with a complete heat sink system is impractical for the reason that it is designed for normal operation. Therefore, it is recommended that the PC use an improved cooler model for these purposes. The second important component is the power supply. Its power should be 650-700 watts. In addition to this, the motherboard must allow paid parameter adjustment and have an increased level of reliability. Also, computers should use advanced advanced modifications of RAM and a graphics adapter. To get the best possible performance from your PC, it is strongly recommended that you equip it with a solid state drive.
Another important feature of this microprocessor model is the presence of an unlocked multiplier. Therefore, to increase the performance of such a chip, only a simple increase in the value of the multiplier is enough. Subsequent generations of Intel microprocessors are largely devoid of this possibility.
CPU Parameters
Before we consider the methodology and procedure for overclocking the i5-750, we present the technical specifications of this microprocessor. This chip must be installed in the LGA1156 socket. The code name for its architecture is Lynnfield.
The CPU includes four blocks of program code processing. The clock frequency of each of them can vary in the range from 2.66 to 3.2 GHz. The thermal package of the chip is limited to 95W, and the silicon base of the CPU was produced using 45 nm technology. The maximum chip temperature is limited to 72 ° C. The CPU case size is 37.5 mm by 37.5 mm. The total number of transistors is 774 million, and the crystal area is 296 mm 2 .
The microprocessor is equipped with an integrated memory controller, which is designed to work in conjunction with DDR3 memory. The recommended frequency of the latter should be 1066 or 1333 MHz. The maximum amount of RAM is limited to 16 GB. To increase performance, the chip is equipped with a cache system of three levels. Moreover, the total volume of the last of them is 8 MB.
Performance Increase Order
Overclocking the i5-750 processor can be done in one of two ways:
- Using special software that allows you to flexibly adjust the current parameters of the computing system.
- Using a basic I / O system called the BIOS.
Since the second method is simpler and does not require the installation of additional software, it is recommended that it is with its help that the PC performance is increased. In addition, special utilities do not always show the correct values of the current computer settings and, as a result, can lead to damage to the personal computer. Therefore, it is strongly recommended that you use the BIOS.
From the point of view of hardware specifications of a computing system, an increase in speed can be achieved by simply increasing the value of the multiplier - the multiplier of the microprocessor or by increasing the clock frequency of the system bus. Since the hero of this material has the first parameter blocked, it is possible to disperse it only in the second way.
In this case, overclocking the Intel Core i5-750 is implemented as follows:
- We preinstall the PC Mark and CrystalMark test packages. They can be downloaded without problems from the global web.
- After turning on the computer, you need to hold down the F2 key or DEL (this depends on the motherboard and is indicated in the documentation attached to it) until the initial BIOS system window appears.
- Using the navigation keys on which the arrows are displayed, go to the menu item OC Tweaker. After that, this BIOS section will automatically open.
- Next, similarly moving between its points, select BLK Frequency.
- Then you need to press Enter in order to select it.
- The next step is to use the PG UP key to increase the value of this parameter once.
- Then we press F10 and exit the BIOS after saving the changes.
- Next, the PC restarts. When the operating system has booted, we check the stability of the computer according to the procedure described in the next section.
- Upon receipt of a successful result, restart the computer and repeat all the steps, starting from the second stage. As soon as the computer stops working, we return the bus frequency one step back. That is, as soon as the PC stability limit is reached, we stop overclocking.
Checking PC stability
In the process of overclocking the Intel i5-750, you need to check the stability of the functioning of the computer. To do this, it is recommended to run the PC Mark test suite several times. If the PC works without comment, then the second stage is a multiple check using CrystalMark. Only after using such software and obtaining a positive result regarding the stability of the PC, a further increase in the frequency of the system bus is recommended.
Speed increase
Overclocking the Core i5-750 allows you to raise the clock frequency of this CPU from 3.2 GHz to 4.0-4.2 GHz. That is, in percentage terms we get almost a 25% increase. In reality, the latter value may be even greater. For example, in the WinRar test, such an increase in frequency allows you to gain 3325 points instead of 2363. That is, an increase in the speed of work by almost 40% is already obtained. Therefore, overclocking such a chip is still relevant and justified.
Conclusion
In this material, the i5-750 overclocking algorithm was described in detail. In essence, it is universal and can be used with any microprocessor of the LGA1156 platform. But to newer chips from Intel, it is already impossible to apply. Starting with the LGA1155 socket, this eminent manufacturer has blocked the possibility of increasing the clock frequency on most CPU models.
