I'm not sure whats wrong, but i kept my core at 1150, and my mem to 1375 and got a score of 1911 on valley which was the highest yet, then i tried it on 1400 and the score dropped to 1700 something so i thought i had gone over its limit.


So i set it back to 1375 and cant get above 1800 again now. Not only that i'm looking in msi and the whole time i run the benchmark the core doesnt seem to be going quicker then around the ~900mhz speed, its throttling badly for some reason.

Use 13.12 drivers and ensure you have +50% power tune set. If you get a crash make sure you restart the pc and reapply clocks before trying again.

Current settings :-

fans auto - volts (mv 1275)power limit +5 % 1115 + 1725 - temp =77 = score 2160

Is the temp are fair temp or it running too hot ?!

Where should i be going from here MV wise , Core and memory speeds....what is the max score i am likely to achieve ? as i may just leave it set as it is if for example , i am only likely to achieve a 2 % or so further improvement.

I do not want to over stress my card , as it is 2nd hand with no warranty , but i would like to overclock to a good speed but not over stress it :)

One thing i have noticed is that if the fans are on full or on auto at the current settings the temp remains pretty much the same.

Advice please ...

Just got a 7950 and noticed gpu-z reports voltages wrong ? I put in 1.00 volts and it's reporting back as it's hitting 1.498 volts when I run heaven bench and click on max voltage hit sensor on gpu-z VDCC.How can it hit 1.498 volts the limit is 1.3 on msi afterburner ?

Does anyone know if the overclocking method on post 1 is still current for overclocking crossfire 7950's on win10? I have sourced the latest versions of the programs mentioned there. Since I want to start playing about with this.

Hi Matt,

Thanks for letting me know. Is there an official stance on 1 bridge or 2? as when I went to 2 bridges, the firestrike bench just seemed a bit smoother and got a small 11 point bump (which could be a fluke).

It's been a while since i tested it to be honest, but from memory i don't recall there being any difference. If you have two bridges attached only one is used.

My card seems to be voltage locked but I can bump it from 945 MHz to 1000 MHz. Got driver crashes at 1025 MHz unfortunately. Haven't tried to find max VRAM clock yet but a bump from 1400 MHz to 1450 MHz works. Was stable for a 4 hour Dying Light session. :D
