AMD R9 270 goes to 300 MHz clocks after a while of playing heavier games, help?

[Maatuuu]

Sooooo, might be the 4th forum i'm asking this from, but into the thing: My AMD Radeon R9 270 goes to so called "2D clocks" after playing a little heavier games, like Battlefield 4 or Mad Max. Just drops frames ALOT.
Only solution to this is to restart the system, after that the same happens if I play the heavier games. I was on 16.1 drivers, tried 15.7 and all between these. It is all random when it happens, sometimes i can play 2 hours or sometimes only 10 minutes. Temperatures are normal (gpu 60-75 and other components around 50-60) I need to have this fixed ...

Could you try to change the fan speed. Here is how I managed to do it.
First, install MSI afterburner - it comes with riva tuner. Then go to settings (don't touch the GPU's voltage and other things) -> Monitoring tab -> find the "GPU1 Temperature" and select it. Then scroll the big windows and find "Show in On-Screen Display" and mark it. Find "GPU1 Usage" in the small windows and scroll the big one and find "Show in On-Screen Display" and mark it.
Second go to Fan tab and modify it. I did change mine to 0-20Degrees -> 20% fan speed, 30 Degrees ->30% , 40 Degrees -> 45%,50 Degrees -> 60% , and so on. Once you press Ok, just minimize the "MSI Afterburner".
Once you start a game , you will see in the top right corner GPU's temperature and how much it is loaded.If you want to modify the message location or color - go to the rivatuner settings.

Once you complete this , test again and post your results.

Ummm.... Now when i did this my GPU temperature goes to 100 celsius when palying battlefield 4 and the heavy games and the lighter games go up to 85 what is not normal, this happens even when i disable the settings from msi afterburner... what happened?
Restarted the pc, temperature still goes 100 celsius... after i close the game the fans are going from 50% of power to 20% and bouncing up and down.......... i think this just did some damage to my pc

Just remove the MSI afterburner - you probably modified clock, voltage or any other setting. This is not recommended unless you plan to overclock.

But the fan speed was 100% and tempeature still 100 celsius... Even when i set the automatic fan speeds the gpu gets very hot.

This is due to the chip overheating over time forcing the computer to downclock the chip in order to avoid destroying the silicon.

Try setting the fan speed to a static %100, and see if ti helps.

It is not natural for any GPU to run at 100% fan speed. Like kwa-e said , set the fanspeed to 100% all the time and test for a short time. If it's the same there is something wrong. it could be some kind of "bitcoin mining virus" , or hardware fault.
