    No CrossFire option in Radeon Settings 3x RX Vega 64 Liquid Cooling



      I have rig with win10 1803 and 3 videocards Vega 64 LC


      CPU: Core i7 6900k

      MB: Asus Strix x99 latest stable bios (non beta)

      PSU: EVGA SuperNOVA 1300 G2

      RAM: Corsair DDR4 64 GB

      NVME: Samsung 960 Pro 1 TB

      Videocards (all): AMD Radeon RX VEGA 64 LC (100-438284)


      In radeon settings no option crossfire, in other rig with 2x Vega 64 LC (same videocards, pcie 3.0 x8-x8) this option exist and work normal.

      All videocards placed in full PCIe 3.0 (x8 - x16 - x8), manual set in bios pcie 3.0 for all slots.

      DDU all drivers and trying different version (18.3.4, 18.4.1, 18.2.1) - no luck.

      In compute tasks all three videoards works without problems (windows and linux).


      Thank you in advance.
