Changing profiles(power states) on a 7950

post #1 of 2
Thread Starter 
The profiles of my sapphire 7950 ref:( http://www.newegg.ca/Product/Product.aspx?Item=N82E16814202007 ) are giving me a little trouble. I have just started OC's on GPU's and excuse me if this seems a bad question, but I have looked everywhere I could trough the forum, googled for an hour and got to nothing ! While doing some benchmarks in a few different applications I noticed my 2D performance results were significantly low compared to much less performance oriented or older cards, decided to investigate. Answer was quie simple: at some times the profiles wont switch, I either get the 300MHz low power profile, or my max state 925 (either stock or OC'd both do the same). Personally, only 2 states isn't a bother at all, I tried to check if the switch happened too fast for me to notice so I made a log and indeed it only uses 2 profiles, lowest or maximum.

My problem is: While it should be in 2D state much higher, it stays on the lowest, low is 300Mhz, and I believe by memory 2D graphics profile is 600Mhz (don't quote me on numbers here !! a user posted all 4 profiles wattage and MHz recently but I am unable to find those again to specify what those are.)
Is it possible to override these in any way ? As I said before I'm not bothered by running on high profiles as heat isnt a problem with the card,
more info:
Stock Settings:
on low power state the card shows 0.950V and while at max power 1.250v
temps never went >42 while testing on stock settings (ran some short benchmark utilities as they enabled me to see the issue pretty fast and note differances)
same results using overdrive in CCC or having it disabled
although I didn't mention it clearly, the memory does exactly the same, it is also following the power profiles low: 150 high:1250

If I forgot anything or you any any ideas/answers/questions, well thanks !

Also, I stumbled on: http://www.overclock.net/t/1313813/new-bios-update-for-gigabyte-hd7950/10 and some user explained there were no profiles in this BIOS version, anyone thinks this could solve my issue ? Im currently running the 015.023.000.001 version.
