[QUOTE=kracker;352023]On my HD 7770 in Catalyst CC there [B]is[/B] a fan control option... also MSI afterburner works very well.[/QUOTE]

What's the sequence of choices/clicks to get to the fan control option?

(A --> B --> C --> D)

Right now, I am not at home so I can't say. But if you don't see it, MSI Afterburner works very well.

In Afterburner you go to the Settings (red circle). In Settings, go to the Fan tab and check "Enable user defined....." Click on points to drag them, or on the line to add a point. Hit Delete to remove a selected point. Click OK.

Back on the main control panel, note that User Define is selected (green circle) and the speed control is surrounded by a green box. If desired, you can uncheck the Auto button, also in the circle, and drag the fan slider to set speed manually. You must press the Apply button for this to take effect.

There are many more setting possible in Afterburner. You can customize the Monitor panel and choose what parameters are displayed. You can set the range of these parameters. Note that if you want your settings to be applied at every startup, you must enable the "Apply overclocking at system startup" item at the lower left of the main panel, [B][U]and[/U][/B] check "Start with Windows" on the General tab of the Settings.

If you click on a numerical parameter on the main panel, you can enter desired numbers. Press Enter key, and click Apply button to put the change into effect. Pressing the Reset button at the bottom sets all values to defaults, including fan control. Click on User Define to re-enable your custom fan curve. "Default" means factory settings for your particular card, including factory OC.

Isn't that easy? :smile:

That's interesting, thanks! Does the MSI Afterburner work on (1) AMD cards (2) that were not not made by MSI?

Fortunately, the weather's turned cool and the problem hasn't come back (yet). But it won't hurt to open the case and look around...

Now, I don't seem to have this AMD Vision Engine Control Center. The only thing I have that's AMD-related is the Catalyst Control Center, which of course doesn't have any of the settings you describe. :unsure:

I have Kracker's word that it works on AMD, but no personal experience.

On nVidia GPUs, it definitely works with cards other than MSI. I am using it with a Gigabyte and an Asus as I write.

Wow, that MSI Afterburner is VERY cool. :cool: And it did enable me to control the AMD Radeon 7770's fan manually. First time I ever heard it blowing!

Unfortunately, that didn't solve the problem (which came back today, with a vengeance -- the card wouldn't run for more than 5 minutes at a time before crashing, even with the fan whooshing). Next thing I did was to update the driver via AMD's website (Windows Device Manager kept claiming that my driver from a year ago was up to date). That, plus a reboot, does seem to have solved the problem, for now anyway.

The machine is still due for an interior dusting; that's coming soon.

Thanks guys for the advice and info.

Rodrigo

Glad to hear you got access to the controls. I hope you can resolve the crash problem. Indeed, dusting never hurts.

I just tried 12.10 with mfakto, still a no-go. [SIZE=1](however clLucas runs fine)[/SIZE]

There are noticeable speed differences between the bitlevels/kernels as most people may have noticed.

On my HD7950 with settings:
SieveOnGPU=1
GPUSievePrimes=82486
GPUSieveSize=64
GPUSieveProcessSize=16


2^65 - 2^68 gives ~250 GHzdays/day uses cl_barrett32_76 (more bitlevels at once)(horrible on 7xxx cards)(LMH range)
2^68 - 2^69 gives ~405 GHzdays/day uses cl_barrett15_69 (DC TF range)
2^69 - 2^70 gives ~365 GHzdays/day uses cl_barrett15_71 (DC TF range)
2^70 - 2^71 gives ~330 GHzdays/day uses cl_barrett15_73 (DC TF range)
2^71 - 2^72 gives ~330 GHzdays/day uses cl_barrett15_73 (LL TF range)
2^72 - 2^73 gives ~330 GHzdays/day uses cl_barrett15_73 (LL TF range)
2^73 - 2^74 gives ~295 GHzdays/day uses cl_barrett15_82 (LL TF range)
