RX 460 crashes and crazy changes of activity and memory

Hello, couple days ago i bought an RX 460, after 5-10 minutes in the game my screen gone black and only thing i could do was to end the task and restart.
I was playing World of Warcraft but after search i 've read that people got problem in Dota2 too. I found a solution by getting GPU frequency down to -16 or even -18 but it's a shame that i have to do that in order to play...

My settings were not that high, mid to low. With my previous 7800 series i had no prob with those setting and it's a 4 years old card!

Besides that, what i am more concern about is that my activity and memory are going like crazy. Activity goes from 0 to 100% and down again and memory is either on 300 or 1750MHz and they both go up and down in those 2 numbers each as you can see in the image below.

If underclocking fixes your issue, then you could have a faulty GPU that is not stable at stock clock speeds. Before you consider an RMA, try using DDU to remove your current driver, update to Crimson 17.2.1, set the Power Limit via Wattman to +50% and click apply, then check the issue status.

Hi amdmatt,

Raising the power limit sounds very scary to me. I have a 460 with the same problem which draws power exclusively from the mobo. Are you sure raising the power limit won't damage my system?

Re: RX 460 crashes and crazy changes of activity and memory

Raising the power limit simply allows the GPU to work at its full capacity. At stock default settings with the power limit at 0%, the core clock of the GPU may not maintain its highest boost frequency. Increasing the power limit simply removes this fluctuation and it may give you a small performance boost.
