Problem with my RX5700XT in Light test OCCT

When i start test in OCCT Stability Test 3d Adaptive (Steady Light 20%) i have black screen afte 40-50 sec.

All other graphics card passes okay! (Heavy 50%, Extreme 100%, Vram test passes to all Okay)

How to fix this? Is it a problem with the graphics card?

Probably is… against “other cards”…
