The only way to avoid that from happen is to manually set your GPU fan profile either using Trixx or MSI afterburner. You have to increase the fan speed and maybe try to reduce the voltage if possible in order to drop the temp during full load/furmark.

another way is open your sidepanel casing . The best is to adjust fan speed of course.

so its suppose to throttle at 82c?

Yeah I think so...your card throttle itself when reaching 82degC. tbh I personally dont recommend you to use furmark to check stability as it will ramp up your card's temp very quickly. I prefer you let your GPU stressed with 3dmark game test loop and Heaven 4.0/Valley 1.0 loop for couple of times.

Now that Crysis 3 out, I would suggest you to play crysis 3 for an hour or two while monitoring your cpu/gpu temps in the background. Make sure to log max temp on gpu/cpu and VRMs. May I know what 7950 brand/model you currently have?

edit: I saw you're using sapphire..is it Dual-X fan one?

i see kk will try out 3dmark and the rest but for now i think i go play crysis 3 and try it out

Yeah im using the dual X one which comes pre-clocked at 950mhz

Hmm I thought an oc'ed 7870 XT can at least scored 40FPS+..is it bottlenecked by your cpu? I've never tried single 7970 with valley though, might wanna test it at stock to compare, btw which driver version you're using now? For valley benchmark you have to install 13.2 beta 6 or beta 7..

My CPU is overclocked at 4.6GHz and RAMs at 1866MHz 9-10-9-28@1T Is it possible that my card somehow reached 82 degrees like another forumer here and got throttled? 82 seems to be quite a low threshold number compared to CPUs at 105 degrees

Yup, now running Catalyst 13.2 beta 7. Maybe I'll rerun Valley at stock and post back

[EDIT] At stock clocks...
FPS: 33.8
Score: 1416
Min FPS: 17.0
Max FPS: 64.6

Created a profile in CCC and set CF mode to Optimize 1X1 with 13.2 Beta7

if driver crash means overclock too high is it?

yes, what you can do is either reduce the core clock or raise Vcore...please monitor your temp closely though. Angain dont forget to monitor your GPU temp using MSI AB osd feature during benchmark/gaming/stress test.

using trixx
currently 1090/1250 voltage(VDDC)-1050"used to be 1012" (so far no driver crash)

My max temp when letting unigine valley on highest setting(in 1440x900 reso monitor too small) is 76C with auto fan speed.

Sapphire 7950 OC edition 950mhz

new to overclocking so advice is really really appreciated xD

Hmm..I dont think you need to OC your 7950 too high if you're just gaming at 1440x900. You can throw any games at it without much issue, set everything at max and I believe 60fps+ is almost guaranteed. Anyway, you may bump the core/mem clocks a little bit and stay there for 24/7 gaming system.

most 7950 will do 1100/1400 with just a small bump on voltage so you can try these clocks, run valley/3dmark/heaven and if no crash or artifacts after couple of hours you shoule be good to go. Unless you wanna play with benchmark then 1200MHz core is achievable on most 7950 but of course with at least 1.2xV needed.

how small of a bump to voltage?

Is it Good or Bad?
7970 Ghz Edt 1150/1600, CCC 13.2 beta 7 with Heaven Benchmark 4.0

ok since you said your default VDDC was 1.012V, then set it to 1075mV in Trixx and set core/mem to 1100/1400 respectively..you can perform stress test or benchmark loop for stability after that. If stable at 1075mV, try to reduce it to 1050mV and rerun the test, It's good to set "board power Li" to 15-20% in Trixx..check max temp during stress test. If 1050mV also stable then you're good. I suggest to play Crysis at Max setting to test those clocks as it's a good cpu and gpu stresser.

Your score is good bro, mine with 2x7970 @ 1150/1600 scored as below. Your score is almost half of my score so it proved that your system is running just fine..the good thing is that Heaven 4.0 CFx scaling is amazing which is 100% improvement over single card

oic, thx, now gonna test my setup on far cry3..

Tomb Raider Benchmark 2013

2x7970 @ 1325/1850
3770k @ 4.8GHz
1080p Ultimate setting + TressFX

alright thanks everything is stable right now running 1100/1400 thanks so much

Did you increase the voltage of gpu? An overclocked card with stock volt wont go that high during max-temp test like using furmark.

I tried upping GPU volts all the way to 1.3V (default 1.187V), but improvements in max clock speed wasn't much... So I just settled with stock volts and pushed as far as possible without artifacts.
