I bought a used XFX Radeon RX 480 8GB GTR Black Edition, before buying i saw a Cinebench test, so the card should be fine.
Now when i use the card i my own computer, it crashes if i play any games or run benchmarks.
Tried to undervolt the card in the AMD Whatman App, Stage 5+6+7 to 1050 mv and Powerlimit to -50. Now the card will run but the performance i terrible.
Computer: Lenovo ThinkCentre Edge 92 Tower
Processor: i5 3470
Motherboard: Generic Lenovo N1995
Ram: 8 GB
PSU: Thermaltake TR2 600W
Early i used a AMD Radeon 7970 with no problems, even overclocking it.
Tried updating BIOS, Chipset, drivers.
Any idea what the problem is?
