A rookie becomes a master! AMD/NVIDIA graphics card overclocking tutorial

If you want to significantly improve the game performance of the platform on June 28, the video card channel of Paobao.com, undoubtedly adding or upgrading a sound graphics card, will get immediate results. If you want to play better on the existing platform Game performance, How to overclock GPU, we naturally think of overclocking. It is also a necessary way for some DIY players to create world records.

Compared to many years ago, both manufacturers and users have realized the importance of graphics card overclocking for performance improvement. The current graphics card overclocking solutions on the market can describe as a lot of flowers. Both develop by non-profit organizations, and some manufacturers give away with graphics cards. According to the overclocking method, there are many, but we divide it into software overclocking and hardware overclocking (refreshing BIOS).

We know that AMD and NVIDIA occupy almost 99% of the market for discrete graphics cards on the market. This article will also focus on AMD and NVIDIA graphics cards to do some overclocking introductions to their respective products. At present, AMD and NVIDIA graphics card overclocking tools are not universal. , Especially hardware overclocking, but the general principle is similar.

The first introduction is the hardware solution. Although the operation has specific risks, it is still straightforward as long as the process master. Here I also recommend users to use hardware overclocking. It has the characteristics of once and for all and not affect by platform changes. Performance can only be achieved through transformation.

The hardware overclocking steps are roughly as follows:

-The first is the test of the graphics card’s physique. If you don’t know the physique of the graphics card, blindly applying voltage or frequency can easily lead to overclocking failure. To test the physique of the graphics card, you need software overclocking and copying software.

-Next is the BIOS preparation stage, users can choose to extract from the existing graphics card or the BIOS provided by the graphics card manufacturer

-Editing of the graphics card BIOS, such as frequency, voltage, fan speed, and other parameters (Don’t add frequency and voltage blindly, control it appropriately)

BIOS import is referred to as refresh. Currently, AMD/NVIDIA graphics cards have more reliable refresh tools. Such as ATIFlash (AMD graphics card). NVIDIA (NVFlash), both software have Windows and DOS versions, although Windows has the characteristics of convenient operation. But it still recommends that users use DOS refresh. The refresh success rate is higher.

At this point, the entire BIOS refresh work is ready. And then the computer can restart. The new graphics card BIOS information will read when booting. And the modified frequency can detect by using GPU-Z after entering the system.

  • Precautions for graphics card overclocking

After refreshing the BIOS (no matter in Windows or DOS environment), you need to restart the computer, and after entering the system, users should not just ignore the graphics card. We have to do a more critical task, which is to verify the graphics card’s stability. Since the unstable work of the graphics card mainly occurs in a high load state, it is best to use a large-scale 3D game or a burning tool. The author recommends that you use Furmark.

Too high a frequency will cause the graphics card to hang or even blue screen restart.

 It is worth noting that even if the graphics card passes tests such as 3D games or burn-in tools, it does not mean that the graphics card will have no worries. A particular game or other application may encounter a screen or hang to avoid this. When overclocking, one problem occurs: we do not choose the maximum frequency that the graphics card can work stably but slightly reduce the frequency to keep its work stable.

Another problem is the power supply-demand and heat control from the overclocking band. Therefore, overclocking should try to choose some graphics cards with surplus power supply, especially those without external power supply ports. It would help if you were cautious when overclocking, and the frequency should not be increased too high.

External Power

In terms of heat dissipation, the increase in frequency will inevitably increase the total load power. To maintain the stability of the heat dissipation of the graphics card, it is recommended to replace the more powerful graphics card radiator. External GPU for laptop, However, at present, most of the first and second-line graphics cards have more heat dissipation. Rotation speed can be satisfied.

The tools used by NVIDIA graphics cards to refresh BIOS overclocking include NVFlash, NiBiTor, FurMark, and GPU-Z are all free software. 

Follow the steps. First, we will verify the stable overclocking frequency of the graphics card. The tested graphics card is GeForce GTX 480, NVIDIA’s first graphics card that supports DirectX 11. Next, we will use Furmark for stability verification.

The core frequency is set to 800MHz

 After some debugging, set the frequency of the graphics card to 800MHz. Of course, the user can also adjust parameters such as the video memory frequency.

The graphics card finally stabilized at 109 degrees Celsius.

Next, we will do the stability verification work. The copy tool selected FurMark. After a long full load, the graphics card is stable at 109 degrees Celsius, and there are no rendering errors. We believe that the graphics card is stable at this frequency. , But we also noticed that due to the immaturity of the early 40nm process, the temperature of the graphics card had reached 109 degrees Celsius. If used at this frequency, it is recommended to replace a radiator with excellent heat dissipation performance or directly use water cooling. Modify the video memory and stream processor frequency parameters under Clock domains

Graphics Card BIOS

After the above frequency verification, we will start to refresh the graphics card BIOS, use NiBiTor to load the original GTX 480 BIOS, and then enter the parameter page to set the frequency, voltage, and fan speed of the graphics card. After editing, you can save the new BIOS. Remember to back up the original BIOS.

Put the new BIOS and NVFlash in the bootable device, and then use the NVFlash command to flash the new BIOS into the graphics card. (Command: NVFlash xxx. com, you can add some control characters such as -4, -5, -6, etc.)

The 3DMark 11 results before and after overclocking were P5637 and P6253, respectively, and the improvement is still pronounced.

The tools used by AMD graphics cards to refresh the BIOS overclocking include ATIFlash, Radeon Bios Editor (RBE), Furmark and GPU-Z are all free software.

 AMD graphics card refresh BIOS overclocking choice Radeon HD 5870, AMD’s first graphics card to support DirectX 11, and the world’s first DirectX 11 graphics card.

The core frequency is set to 900MHz

Graphics card stabilizes at 88 degrees Celsius

Before flashing the BIOS, it is also the best overclocking frequency verification for the graphics card. Use the soft overclocking tool to set it to 900MHz and pass the FurMark copy machine. The final temperature is 88 degrees Celsius, and there is no rendering error.

 Next, load the BIOS extracted by the graphics card into the Radeon Bios Editor editing tool and adjust the frequency, voltage, speed, and other graphics card parameters in the parameter settings. After the adjustment complete, save the new BIOS and also remember to back up the original BIOS.

Finally, in refreshing the BIOS, put the new BIOS and ATIFlash tools in the bootable device and then use the ATIFlash command to flash the new BIOS into the graphics card. The refresh command: ATIFlash -p 0 xxx. rom, you can also add some control Symbols such as -f and other parameters.

The 3DMark 11 results before and after overclocking were P4655 and P4843.

Compared with hardware overclocking, software overclocking has the characteristics of easy operation and convenient overclocking. Still, it is affected by the restrictions of each bootload and lack of platform migration, which affects the user experience.
