The combination of two mid-range graphics cards offers the same power as high-end graphics cards. However, this solution also has its own advantages and requires readers to understand computer hardware. There are a few things you should know about dual graphics technology.
Upgrading the graphics card more powerful will significantly improve the processing power of the computer, especially players have the opportunity to “icebreaker” more games. However, in terms of financially limited or simply improving the multi-processing capabilities of existing configurations, the solution runs dual graphics cards with CrossFire or SLI technology, no less. However, “the craft is also very elaborate,” so that the CrossFire / SLI system effectively requires users to have the knowledge and experience of computer hardware.
Dual graphics technology
- AMD CrossFire and Nvidia SLI.
Basically, AMD’s CrossFire and Nvidia SLI (Scalable Link Interface) technology helps the PC run and utilize the power of multiple graphics cards in graphics and imaging tasks. This technology provides up to 4 cards on CrossFireX / Quad SLI or 3 cards with 3-way CrossFireX / SLI and 2 cards with CrossFire / SLI. Hybrid CrossFire / SLI graphics combine with integrated graphics (IGP) and discrete graphics (GPU), which is commonly used in notebooks.
- Hardware setting
Crossfire / CrossFire / SLI cards are quite simple. Use a bridge (included motherboard or graphics card) and activate this technology through the driver (card). However, check the following points before doing so.
- Motherboard Support: Bypassing older motherboards that support the outdated AGP 8x interface, Digital only mentions the upgrade of existing PCI Express x16 PCI Express graphics cards. . Specifically, the motherboard design must have two PCIe x16 slots and support either CrossFire / SLI technology or both.
- Choosing the right power supply: In addition to ensuring the power required for the entire system, the power supply must have a power supply line + 12V (for graphics cards only) to the manufacturer’s recommended level. You can rely on the hardware specifications or use the utility as eXtreme Power Supply Calculator or Thermaltake Power Supply Calculator to calculate the power required to meet.
- Configure the software
Download and install the latest driver from the manufacturer’s website. With the AMD graphics card, launch the Catalyst Control Center utility in the right corner of the screen, select Performance and check the Enable AMD CrossFireX option to enable this technology.
Similar to Nvidia graphics card, start up the Nvidia Control Panel, select Configure SLI, Surround, PhysX in the 3D Settings section and set it up as shown. Next, click on the 3D Settings item on the menu bar and check the Show SLI Visual Indicators option; this is also a way to test software, games that support SLI or need to update the driver (or profile) accordingly.
The born of dual graphics technology has brought a lot of change and benefits to computer users. Thanks to the information above we can have a deep understanding of this technology. However, in order to apply this technology, you need to achieve necessary knowledge to master it.
