GPU Performance Problems HELP!

[Navardi]

hey so every since i updated to 14.7 beta driver for my AMD R9 270, i have experienced performance bugs, now without a restart 3 times in a row my gpu will stay at core clock of 300MHZ and 150MHz for the memory clock (this is generally the setting for the card at idle) so when i launch up BF4 or Dota 2 my fps will range from 1-5 15-27 or 0-3 it wont matter what the settings are or resolution nothing fixes it. but after going to back to 14.4 and using the amd cleanup utility i was abe to get it working temporarily and now the only way to fix it is to restart 3 times in a row. i havent changed any other software or hardware settings and everything is still the same before this glitch occured. i have overclocked the card but only to the settings Slick said to use which is basically max out all the settings. the GPU stays around 15-20 degrees celcius and underload which now only occurs when i run msi kombuster it sits at 50-60 degrees celcius. so i need your help i have also contacted amd but who knows how long it will take for them to reply.

try this

do a clean uninstall of the drivers

 

then re-install the 14.4 drivers

 

revert back to stocks clocks using MSI Afterburner

 

and use GPU-Z ID to check load and temps

 

use Unigine Benchmarks or FIreStrike

 

last resort is to re install the OS to clear out any troubles relating to software
