Thank you from S.Korea!

Well I tried the DDU again, It's so strange that it only happens in LOL but yet it just crashed again.

Not giving up yet, Thank you for the reply!

I'm having the same problem too.

It crashed every 7 minutes and 7 seconds.

Known methods have been applied, but they are still unresolved.

I still having the same problem, I tried to ask the LoL support team but they didn't solve anything. Does anyone here solve the problem and can share with us? Many thanks.

did you use DDU in Safe mode. also watch temps when playing league of legends set your metrics to on in Radeon software / performance / metrics tab Goto overlay and show metrics overlay, watch your temps for video card and cpu.. another thing to look at is your CPU voltage i have an issue with my mother board sometimes where the voltage sets itself to offset and won't have enough voltage and runs really slow and would crash sometimes just go into bios and set it back to manual or auto  auto better. I use CPU-Z to check voltage as the metrics from the amd software doesn't show my voltage for the CPU

I think i finally found a solution, It's from reddit.
Played 2 games each with 20+mins it went smoothly.
God it took me that one whole month.

Thank you.

Thanks for the advice, I tried but it not work for me...

Well.. yes, now I'm getting the same crash too.

Played 10+ rounds smothly and then same thing happened all again.



oh... I feel bad for you, anyone else in here solved the problem and can share to us?

I finally find the solution of it!!!

Go to the League of Legends Client > Setting (on the top right) > In- game > GAME > Tick the Prefer DX9 Legacy Mode

It completely solve the problem and I played for 2days without having any crashes!

Hope it helps you

Thank you ! I had the same problem and it was fixed this way... Strange solution, in my opinion


Edit : In fact, it did not work for long, but working the game with DX9 seems to have sold the problem
