Thanks for explaining all this slickric21 !
From your above statement I conclude that for the overclock to be active all the time you need to have Trixx running or at least run it once on every startup. Correct?

Correct mate,but just run it once per bootup is all thats needed

There is an option to "load at start up" but i dont use it, as i only OC for BF3 i just set it manually - i dont want a OC for every 3d app !!!!

Special Note:

Edit: Well I just installed it and using Custom, it confirmed that it is a newer driver than the official RC beta. No release notes that I can find yet either. No issues so far... maybe MSI gotta hold of a new one before AMD put it out to the rest of them. Interesting politics behind the scenes there in that case... I wonder what the other "top tier" partners will think of that lol...

Its an old driver from Dec repackaged

Edit: Both problems fixed, just disabled ULPS in regedit. (I'll leave the questions there in-case someone else needs them)

I need some help guys, both questions and pic here smile.gif

Just got my second powercolor 7950 and the oldest one is just 1 week old. Super happy with them, but got some questions/problems with crossfire.

1: I can't change voltage on second card in trixx, why ? Afterburner i have tried but no luck.
2: Why is the stats sifferently on the pic below ? Its card number one and 2, see the underlined stuff...

beggenyekorta.jpg


Lastly i just went mental on the plate under the second card...haha. With my mobo the psi slots are 1-2 places down, so the bottom card go so sandwitched so i just bent the hole middle of the case... works like a charm biggrin.gif

Thanks alot for your help mate, I now understand the program abit better.

I know tried some mild overclocking in Trixx setting my sapphire HD7950 OC to 1000 core and 1500 memory and raising the voltage in Trixx to 1175. After testing with GPU i can now see clearly that my volts are higher.

I can see the following after couple of minutes doing the render test in GPU-Z :


Temp 65 @ fan 47%
GPU load around 97-98%
12V - 12,06 V
VDDC - 1,129 V
MVDDC - 1,602 V
VDDC Current - 77,5 A
VDDC Current In - 8,4 A

Can someone explain me these voltage settings?
Is this any good? And can these numbers tell me how much I can push further?

Thanks for explaining!

I have powercolor 7950, using 1100/1500mhz @ 1200mv... do you have the dual fan one or reference one ? You could probably go higher than that with that voltage

Thanks for the reply. I was wondering where all the excited responses were! :)

So hopefully no harm done, at least I haven't noticed anything different yet. I shall try and run Crysis later on, which so far won't run at all without a hard system lock after about 1 second of major screen corruption, even on stock clocks and voltages. I also get the same problem after about 30 mins - an hour of Farcry 2. And can't run Metro Benchmark or 3DMark11 at all go figure...

 

If this driver changes anything I shall report back. I'm an optimist hehe

Thanks for your help (and slickric !)

I have the dual fan one.
After testing 1 min in Furmark at 1000/1500 and 1175mv my max. GPU temp is 75 ...
Is that something to worry about? Or is that pretty "normal" at these settings?
