What is good settings for my ATI R5770?

After driver restart app can't continue. It will either take 100% CPU core or just hang.
And driver restart itself just consequence of low GPU usage => too long kernel execution => Windows thinks driver hang => windows restarts driver.
You can try to get rid from these driver restarts by disableng watchdog in windows registry.

I never get a driver restart ?
Mostly it cures itself on the next task.

[Raistmer]

yes, next task will be OK cause it creates new OpenCL context.
But after driver restart current app instances become invalid cause their OpenCL contaxts become invalid.

This low GPU usage bug is driving me nuts

Right now I cant get my GPU to crunch anything AP at full speed.

The last many WU's have been the 30% for a few seconds, then 0% for 10 seconds patterne. WU's take forever.

Making it crunch 2 or 3 at a time gives same the results.

Any number of starts and stops of the boinc client, doesn't help.

The funny thing is I didn't have this bug before i began to tamper with the settings, to make it go faster.

Are there any tricks to make it work better? Never Boinc, other drivers (I'm on 12.3), or anything. This is more than mildly frustrating...

A reboot of the system cured it, but well see how long it lasts.

I am running a absolute stock settings from Lunatics installer, to see if it lasts.

I'm not sure that any app settings connected with this issue anyhow.

[KarVi]

I'm not either.

But as I hadn't encountered the issue before starting to tamper with settings, I thought it worthwhile to at least try to run with original settings again.

Its still working, but I need a little more than 1 and ½ WU to see if its cured, or at least reduced.

If suspend and resume dont work you need to restart.
