This is my card

MSI RX Vega 64 | TechPowerUp GPU Database

The room temperature is 26 С.

In balanced mode ( BIOS 1 and BIOS 2) does not pass the stress test 3D mark Time Spy after 10 minutes, the test hangs and crashes with the error "0%,test not passed".

Firestrike stress test is "96%, test not passed". Also, RX Vega 64 hangs in many heavy games (The Witcher3 or Hellblade).

GPU temperature  in stress tests - 83 C

  The tests 99% passed only when  the fan speed is set to 3300 rpm, or P5 is selected as maximum (1310 MHz in applications) at a fan speed of 2400rpm (default), that is, at a GPU temperature of 76 ° C
  This is on all versions of the drivers up to 17.11.4

 

This is normal?
