Newer variant of Catalyst (8.892)11.9 out(might fix 100 % CPU bug).

[Beta-coiner1]

       It looks like the Catalyst 11.9 are finally out and some here have mentioned it gives a nice performance boost without the 100% CPU bug being prevalent.

If this post has been helpful donate,lol !

Edit: A newer variant of the Cat. 11.9(8.892) has been released ! Although,when I tried these the bug is still prevalent.

If this works I will make passionate love to any member (or all members) of the development team.

On a 5770 this fixes the 100% CPU bug and a small increase of 2-3MHash/s on poclbm. Nice!

Thanks for letting us know about 11.9 I've been waiting

Am I the only one that the bug is not fixed?

I've got two cards locked down to one core of the four cores I have, other wise if not locked down, each card maximizes one core per card.

Two 5830's.

Reduces cpu usage massively on my 6950s and gained about 5mh/s.

I won't be rolling it out on all my machines as I don't really trust rc drivers.

unfortunately this did more harm then good just spent an hour fixing the computer but maybe its just me i never had the 100% bug my comp always sit around 50%. lol you guys are happy bout 3mhash

Perhaps it sat at 50% because you have a dual core cpu and it was only using 1 core? Also, I'm not massively thrilled at a 5mhash increase, but over 10 workers that's potentially 50mhash, and I'm certainly not complaining at that.

Also, an hour? really?

The bug make a core run at 100%, if you have a dual-core cpu of course total cpu usage is 50%.

Been using it since yesterday. It's good stuff.

[pekv2]

Even though it's a RC, it doesnt look to damn good. It is the same as 11.6, 11.7 and 11.8.

For the ones stating "it is fixed for me", can you post what hardware you are using, OS, everything.

See, I never had this problem with 10.11 drivers with 2.1 sdk, but moved to 11.8, 2.5 sdk and newest guiminer for more mhash/s, a while back.

dub0matic, what do you mean, "spent an hour fixing the computer" what happened? BSOD? Did you not click allow driver signing install button upon 11.9rc installation?

I would like to see these specifics for all that it worked and didn't.

direct link to 11.9rc on amd's website please?

[fcmatt]

thanks. i prefer downloading such software directly from amd.
i will just wait for a few more people to chime in with their results before taking the plunge.

Yea for the time stopping the miners, then uninstalling, then running driversweeper in safemode, reboot back into safe mode to clean the registry with registry cleaner, then boot back into windows normally, install 11.9rc, then reboot again is not worth the hassle atm.

I highly doubt this bug fix will be implemented in the final release of 11.9.

This is why i leave miners running unless something BIG happens, they're running now mostly on 11.6 except for rigs with more than 4 cards unless 12.0 brings a huge jump in performance or allows better overclocking/lower temperatures somehow it's not worth the effort, how long does that 4mh boost take to cover an hour of downtime when you're already at 1gh per rig?

[dub0matic]

what mean by an hour is i installed it checked to see if it ran didnt seem like much of a difference so i rebooted then had trouble restarting. then when it actually started up guiminer would just say connecting not shares or whatever so then i had to go back to 11.8/2.3. cool story bro ill try it again when the official release is out

[deslok]

uninstall and reinstall cleanly is about 20 minutes including a reboot getting things overclocked again plus any issues with the new driver that have to be dealt with i'd give an hour

It takes an hour to install a driver?

to do it "properly" does take some time.
now if you just slap the new driver over the old and reboot.. well that takes less time but sometimes
causes a lot of havoc.

and deslok makes a really good point.. of just how long does it take for an extra 4 mh/s to make up for
a 1 gh/s box being down for an hour?

i think it would be about 10-11 days.

1000 mh x 60 seconds x 60 minutes = 3,600,000 mh/hr
4 mh x 60 seconds x 60 minutes = 14400 mh/hr

3,600,000 / 14400 = 250 mh/hr

250 mh/hr / 24 hours = 10.41 days at 4 mh/s

rough math. i prob made a mistake. dunno. need to think it through more.

[deslok]

Seems in the ballpark i was thinking, changes to the mining programs are one thing and usually simple to install driver changes can be hell and require complete reinstialls if things go sour enough
