hey guys, not sure if i have a serious problem here or not,

bought a 7950 about a month a go and all is well and its working great, but today i notice it makes a whine when under slight stress, for example when i open minecraft and log in it makes a constant whine, then the moment i close the program it will instantly stop.

i have also noticed that it is idling at around 55 degrees now, which i know isn't an awful lot but until not it idled at around 40.

the card i have is the MSI Twin Frozr

what do you guys think, should i be worried? :(

Thanks
 
Are you running the 12.11 beta driver? If you are it's probably because your idle clocks are borked. The whine is coil whine, run Heaven overnight and it should lessen the whine.
 
Coil whine seems quite normal with AMD cards (I am guessing that is what you are hearing). The idle temps do seem a little hot though. You should give everything a good dust down and blow the card out with some compressed air. If that doesn't improve temps, you could try reseating the heatsink whilst replacing the thermal paste.
 
It's normal to hear slight whine in game menus but should be silent in the game itself,idle temps should be around 28c,so my guess is it isn't entering idle clocks as stated above
 
are you running single screen 60hz?
is it clocked or standard,
And in gpu-z are the clocks returning to idle states and the v-core too?
 
I'm running the 12.10 drivers, although i only updated them recently so it could be that?

i just ran the render test on gpuz and the temp is at around 70 which i think is normal? so i don't think its a cooling issue, and i don't hear the whine under full load either!

yeah its a single 60hz(i think) screen, 1920x1080 and its clocked at 1000mhz core and 1575 mem, although i tried at stock too and its the same.

i think ill roll back the drivers and see if that helps, cheers guys :)

ill try rolling back the drivers and hope that fixes it

Leave the driver, open CCC and drag your memory clock to 150mhz and click apply. This will keep the 2d memory clock low at idle and ramp up as normal in 3d mode.

okay it looks like that works the clock goes down to 300mhz instead of 500 when idle and its running cooler thanks! :)

one question though, under load the memory runs at 1250mhz now instead of the 1575 i could previously have it set as, is there any difference in performance having it lower? the clock speed is still at 1000mhz

thanks :)
 
Click on defaults in ccc overdrive,I've had to do that a few times on older gpu when it sticks on 3d clocks

Click defaults a few times as said above, and if that doesn't work roll back to the 12.8 driver. AMD are aware of the idle clock bug on 12.10/12.11 and are working on a fix and should either be released as a beta5 or whql.
 
no luck with the defaults, keeps going to 500/1250 idle, but I've rolled back the drivers and its now working properly! sitting around 35 degrees!

thanks for the help guys i appreciate it :)
