True, but aren't CCC and AB/Trixx all "authorities"? Do people disable or uninstall CCC when running other O/C programs?

 

I also wonder if having multiple programs accessing the temperature sensors at the same time affects anything eg CCC, Trixx, GPU-z , Speedfan.

 

Thanks

Uninstall everything, Catalyst, Trixx, SpeedFan, Afterburner. Select no to keep the settings then go to delete the install folders. Becasue each application set and keep a set of profile with instructions linked at drivers/registry level. If you have more than one = crash.

Clean it with Atiman Uninstaller v.6.2.0
 

Install in this order;

-Catalyst

-Afterburner if you decide to use Afterburner.

-Disable ULPS if crossfire.

-Enable unofficial overclocking if you OC with Afterburner.

Do not override Afterburner with CCC Overdrive or Speedfan or others.  

It does and you don't want to do that. Because all hardware monitorings will hurt performance. It will access the hardware level at a certain period of time to display the readings and that takes resources. If you have more than one, it will hurt more if not crashes.

When it happens, blaming the drivers will not fix it lol.

Thank you for the great reply. Be it luck or good fortune, I deleted AB, stopped running Speedfan, and rebooted. Just using CCC to set the Power, then leave it alone, and Trixx for everything else. set at 1100/1500/1200. Just got some really impressive benches with Dirt 2 DX 11 and Far Cry DX10. Not the latest or most demanding of games I know, but the drivers for them seem relatively stable.

Since doing the benches about 30 minutes has elapsed. It's a very hot day here, well into the mid 30's now. Not one issue in Windows... yet!!! So thank again perhaps it was AB or perhaps it was Speedfan.

I'll do some more benches later, Batman AC, maybe Metro and do you recall whether Mass Effect 2, Crysis or Deux Ex HR have built-in benches?

At 1175, if I added 1.22 on the voltage, it would crash in OCCT in about 3-4 seconds with hard lockup of the computer where I had to reset it. I lowered the voltage down a notch each time and it lasted longer in OCCT. My goal was to reach 30min without more than 10 errors. I had more than 10 errors at 1.187 and then only 4 errors on a 30minute run at 1.181.
I cannot go any higher than 1175 with any voltage right now -- I get mad errors to a crash in a short amount of time. I kept my fans running 100% and never went over 72c so temps were not the issue. Does anyone else have any recommendations on the chip to get it that extra 25mhz?

I'm sure you know way more than me about these things, but just a thought: No denying OCCT is popular, but in a similar way to Furmark it puts the card through some loads that are rarely experienced in real-world gaming. Isn't it quite an old program that people primarily use because of its error-reporting function? Correct me if I'm wrong.

Have you considered, or done, some game benches for testing instead. I wonder whether you might actually get better results with no artifacts or problems doing it that way. I'm not thinking Batman or Metro, since the drivers are too immature to rely on their beches, but say Dirt 2 or 3 with the built-in DX11, or Farcry Ranch Ultra DX10. My 2c :)
