Card core clock and memory clock spike

[Oniel100]

i have a radeon 7950 gigabyte with a amd quadcore athlon x4 640 3.0ghz with 8gb of ram 800 watt powersupply and 1tb hardrive. Card is average while playing the game 300mhz core clock and sometimes spikes to 510mhz for a second. memory clock spikes to 1250mhz (which should be the constant clock). none of this is constant don't know why. have played games and tested at the same time with same result. newest drivers so should work fine. don't know whats wrong any ideas? thanks. (also no viruses already scanned twice)

I've seen many cards spike their clockspeeds at idle, usually it corresponds to an application loading for the first time. the 300mhz core clock is the usual idle clock, and while gaming the card should clock up to about 1000mhz. if the spikes only happen while idle i'd say that's pretty normal, but if that's happening while gaming, the issue here is that the card isn't clocking all the way up as it should.

what games are you playing?

was playing Garry's mod maxed out and only getting 30-45 fps and drops to 12 when intensive things in game happens.

what kinds of temperatures do you get? I've seen two reasons why a card would run on its 2D speeds.

It's running too hot: Try cleaning it off as best you can and make sure temperatures are below 80.

The driver crashed: This might be caused by an unstable graphics card. Try dialing your core/memory clock speeds down 25MHz, then restart.

what program would i use to dial it down and restart? could you give me some steps or instructions? That would be very helpful.
