HD 7950 Behaving Strangely

[KingIan95]

Hi, was hoping someone could give some advice or an explanation. Recently purchased a new system and the HID HD 7950 has been acting strangely. Been playing ACBF on pretty much maxed out and getting an avg fps of 39, which I was happy with for a while but got bored of soon enough. So just a basic overclock from 800mhz to 950 with power limit upto 15% and mem clock at 1575 from 1250, stress tested fine in game was getting 45 avg, success. The next day not so good. Sitting around 24fps in game, reset it to defaut sitting at 20fps. Any Ideas what I've done? 

 

Cheers

You not tried running something like Furmark? Just doing an OC then jumping directly into a game isn't the way to do it. You need to stress test to make sure it's stable.

You could always reinstall the driver and see if that does anything though if the overclock was to blame taking it back to default like you have should set it back to normal

Yeah Furmark was the one I used, ran a little hot but was stable till the next day anyway. That was what i thought anyway, may need to re-install the drivers then

If you happened to get "driver stopped responding bla bla bla bla and recovered" shit, you need to reboot your system else you will get some derp performance and also, stop using Furmark.

No not getting any of that, just piss performance in games. Used Unigine as well, getting decent scores but in game its pretty poor. Should I play with the voltage? Never thought i would need to, only 150mhz above stock clock

you should check the gpu usage and frequencies while gaming.it should be a pretty flat graph in GPU-Z or Afterburner.

If you are getting bad FPS after resetting to default but still getting normal FPS with unigine then it's the games fault in some way.
