I have recently installed a pair of MSI™ AMD™ Radeon™ Vega 56 air boost oc graphics cards to run in AMD™ Crossfire™ on the AMD™ Ryzen™ and MSI™ x370 platform with 16gb of high speed DDR4 memory running at 3200mhz.
I installing the two MSI™ AMD™ Radeon™ Vega 56 graphics cards, I installed the AMD™ Adrenaline™ software,
I then installed Steam™ game client and the epic title of Fallout™ 4 for pc.
I also installed MSI™ afterburner™ software to monitor and analyze the AMD™ Radeon™ Vega 56 gpu's doing the load.
I found that on the first attempt to run the application Fallout™ 4 that i was stunned to see the two cards worked in Tandem and I was pleased to see this happening though the use of MSI™ afterburner™ software monitoring.
the work load of fallout™ 4 was distributed across the two AMD™ Radeon™ Vega 56 gpu's at 1080p on ultra settings.
I then tried to run the application Fallout™ 4 again and found that only one AMD™ Radeon™ Vega 56 was working.
I have been unable to get the Game Fallout™ 4 to run correctly since at 1080p setting.
I tried the application AMD™ adrenaline™ reset settings and run some tests on everything I could and gained nothing performance wise from my efforts, a great deal of time has been put in to the AMD™ Radeon™ Vega 56 Crossfire™ for these results.further more, tests have shown that I can get the AMD™ Radeon™ Vega 56 Crossfire™ to work but does not seem to work at this time any more at 1080p while running the application Fallout™ 4.I have tried to enabled the AMD™ Crossfire™ fallout™ 4 profile, but this did not improve on the performance that the first attempt did receive.
I tried to run the application Fallout™ 4 on AMD™ Radeon™ Vega 56 Crossfire™ at a Virtual super resolution™ of 2160p.I found out it was capable to delivering a shocking 4000mhz on one of the AMD™ Radeon™ Vega 56 gpu's while playing Fallout 4 at 2160p and both AMD™ Radeon™ Vega 56 gpu's would strain to deliver the load at maximum performance.
below is a list of settings you might like to try to attain the amazing thrill of AMD™ Crossfire™ on your system, please be aware that an EVGA™ 1000 G2 psu like mine is recommend.
1. Fist, install your AMD™ Radeon™ Vega 56's in to the two Pci-Express slots one and two.
2.install the AMD™ Adrenaline™ software package,
3.select the option in the driver for AMD™ Crossfire™.
4. install and run the MSI™ Afterburner™ software and select the item you wish to monitor in game.
5.run the application Fallout™ 4.
6.Please enjoy one AMD™ Radeon™ Vega 56 running at 1150mhz while the other runs at 300mhz.
Please let me know if there is more step's you think I should take to enable AMD™ crossfire™ on the AMD™ Ryzen™ and MSI™ X370 platform with high speed DDR4 memory.
