Topic: Mining with Catalyst 11.9rc (Read 1896 times)

Gone for more than 1 card?

the cpu bug is gone. already installed cat ver 11.9 

Installed 11.10 preview: no cpu bug with a single gpu.

Yay!

Yep, 11.9 are out!

11.9 release out.
Win7 ult x64.
Single GPU = no cpu bug up to aggression 10. Aggression 11 = 40% cpu, 12 = 80%, 13+ = 100%.
2+ GPU = 100% cpu bug, can't be fixed at all by miner settings.

11.10 preview out too, havent been tested yet.

Hi,
Someone tried the 11.9 in seven x64 ? (I am a 400mh / s with 5870 @ 0,9GHZ, sdk 2.5, driver 11.6)
Thanks 

Anyone could pop in here stating that because they forgot to mention they are not on these drivers on Win7.

Using something like 11.5 & Linux?

I heard the 100% CPU bug wasn't actually a bug, but a feature. At high GPU usage, the card offsets some of the load to the CPU. I'm not claiming this as fact. This is just what I've heard.

Anyway, I just restrict all my GPU miners to a single CPU core and that keeps them from eating up all my resources. They still mine just as fast.

I am running with 3 cards, no issues at all.

mine still runs at 100% with 11.9 

What I think is going on, is, the bug is fixed for a single card setup, but a dual or + more cards, the bug remains.

I've got dual cards, the bug remains.

No change at all here.  Still 100% CPU.   Win7 64bit.  4 cards.

I am getting mixed results:

Geting 100% on an AMD Athlon X2 3800 with 5770 and 5870.
On Intel Quad Q9550 with just a single 5750 it is back to almost zero.

This 11.9RC seems to be the first driver release that doesn't definitely have a CPU bug since 11.6 original. I'm only running single GPUs per machine, and one advisory that ATI had was for CPU usage with multiple GPUs, so it may be different on multi-GPU rigs.

The mining software seems to make a difference, for example, running phoenix source off of python 2.7 and the mix of libs I was using caused cpu usage around 5%, but running the exe and it's included python distribution is less than 1%.

Also to note - the XP install doesn't work correctly, after a driver wipe, reboot, and reinstall of the newest and another reboot, XP still came up with the VGA driver installed. I had to manually install VC++ 2010 and manually browse using device manager to the driver, and then it complained that a file was missing during install. Ignoring the missing file seems to have gotten everything going.

Good for another mhash/s.

Confirmed 100% CPU bug gone.
setup WIN7 64bit, single 5850@960/322 1.15V
also 1-2% more Mhash AND a little higher temps
As espected Afterburner shows an increse in GPU utilliasion from 97-98% to solid 99%.
i know "solid" is a burned word in bitcoin comunity. lets burn our cards at 99% GPU and 0% CPU
 

Something else I've noticed, on 11.6 while mining and watching flash videos, my gpu used to clock back from 1GHz to 300MHz. Now it only clocks down to 900MHz. This could've been done in .7 or .8 I guess, but I jumped them because of the 100% cpu. 

Okay, I figure it's worth mentioning: those noting 100% CPU usage (an issue I originally thought was deep embedded in the miner program itself), you do realize that CPU usage is directly related to "aggression" sorts of setting, right? Some clients don't even offer aggression tweaking and will inherantly over-utilize the GPU, causing high CPU usage. Those using phatk variants, Phoenix, etc., with aggression settings, have you tried playing with those yet?

I'm going to give the 11.9 a try (currently using 11.6 with settings tweaked just on the very edge of provoking CPU usage), but I figure I should throw that out there.

edit: Mhm... well, I installed the 11.9, and I saw... well... precisely zero difference whatsoever. Still exactly the same 211Mhash/sec as always, and a dead-cold 0% CPU usage. I wonder if I can push up the aggression factor a bit without increasing CPU usage, though... but hey, this is still better than the 100% CPU usage others have whined about. Although I do wonder if that, itself, was related to pushing aggression up too high... =P

edit: Ooh, shiny! Managed to push it up from 8 to 9 with 0% CPU, but 9 to 10 sparked a 10% utilization. Going from 8 to 9 boosted Mhash/sec from 211 to teetering on 213 (bouncing between the two), so hey, it's a start! 9 to 10 with 10% CPU had it bouncing on 213-214 pretty steady, but the additional power consumption would probably negate that benefit - I closed down TeamViewer just to see if it was affecting it, and it didn't make a difference: 10% steady. So it's back down to 9 for me, but still a good boost. Yay, progress!

Usually yes, but I've used driver sweeper and registry cleaner, I still have this 100% core cpu bug on 11.9, few others have confirmed the same, the bug is still there.

Has anyone tried 11.9rc with linux?

I just installed and mine not long ago, the CPU usage is in fact quite low.
