![]() ![]() You do require drivers for CrossFire for setting up a multi-GPU configuration for AMD Graphics Cards. AMD Radeon Graphics cards that do not require CrossFire communicate through PCI Express Lanes or Bus. But most of the older generation AMD Radeon graphics cards require CrossFire Bridge for working in Crossfire. Not all AMD graphics cards, especially the latest ones, require CrossFire Bridge for CrossFire Configuration. Not all motherboards having multiple PCI Express x16 graphics card slots support Crossfire as some of them support SLI only. The other major requirement of Crossfire setup is Crossfire Ready Motherboard or Motherboard that supports CrossFire. You can look at the compatibility list below of CrossFire graphics cards showing which AMD graphics cards are compatible with another in CrossFire configuration. Unlike Nvidia SLI, two graphics cards having different GPUs may work together in AMD CrossFire mode depending on their compatibility. The first requirement for setting up a CrossFire configuration is two or more CrossFire Ready AMD Graphics Cards (up 4 GPUs). In any case, we are not responsible for problems with your system.Here are the various requirements for setting up a CrossFire setup on your computer using multiple GPUs. Use this code only if you know what are you doing.

In the end, disable CrossFire and enable Compute Mode with a one-click patch. Use AMD/ATI Pixel Clock Patcher if your cards have BIOS modifications. AMD driver – Install fewer things to get more stability Use OverDrive’N’Tool to overclocking and undervolting your cards. Select ‘Custom Install’ and check ‘AMD display driver’ only to get more stability. Radeon Software Adrenalin Edition 18.6.1.Radeon Software Adrenalin Edition 18.5.1.Radeon Software Crimson ReLive Edition Beta for Blockchain Compute.Newer Adrenaline drivers, like 18.12.3, can cause instability issues or ‘invalid share’ errors under miners like XMR-stak. The best way to have a stable mining rig under Windows is to use the Radeon Blockchain driver with Compute Mode enable by default and disable CrossFire only, or using the Adrenaline 18.5.1 or 18.6.1 driver, disable CrossFire and enable Compute Mode. Specifically for the Windows system, the best way to do it is by using the Registry Editor. Learn how to do it in a simple and easy way. To have a stable and fast mining rig with AMD cards and Adrenaline drivers, one of the basic things to do is disable the CrossFire option and enable the Compute Mode of the driver. ![]()
