Topic: Newer variant of Catalyst (8.892)11.9 out(might fix 100 % CPU bug). (Read 7626 times)

Installed 11.9 on my 2x 5830 Win7 32 bit system and the cpu bug remains. No changes in performance.

I did just slap the new drivers over the old though so I'm not sure if that makes a difference.

11.9 final installed on two systems (Win7 x86 w/ 5750, Win7 x64 w/ 5830). 100% bug is gone on both.

already used 11.9, and it works. removing cpu bug but not improved performance 

Yea one system has a 6850 and the other a 5750. Both no longer run a cpu core at 100%, total cpu usage stays around 1-3% now.

With 11.9, I can verify that at least w/ one GPU...the 100% mining bug is GONE! yes! FINALLY.
Bet that saves me a few watts =)

Im runnin Vista 32bit, i3 550 @ 4ghz 1.175v, HD6950 1GB @ 890core 150mem

No change in mhash(373mh/s) from previous 11.8 version! yay!

Single GPU?

It fixed the 100% bug on both of my systems.

I'd go so far as to say the keys are mislabeled on his keyboard... that'd be 10+ typos lol
But yeah, surely he's referring to an unlocked 6950...

installed it on my htpc with single 6770. works, 1-2% usage. vista 32 bit. cgminer.

method: express uninstalled 11.6, ran drivercleaner in safe mode, installed 11.9rc.

Windows 7, 2 nos. of 5870, 11.9RC (sep 9)release & APP 2.5, don't solve 100% or less CPU usage.
Each phoenix uses 25% of CPU usage.

I agree, DeathAndTaxes. I have 2x5870 with 100% cpu usage. And I have single 6970 cards on a few PC's, on which 11.9rc fixed 100% usage.

I *think* the newest beta version ONLY fixes the bug with single GPU (or maybe it is single card).

Looking on AMD support forum it looks like there are actually two bugs. One bug only affect multi-GPU and the other affects all cards.

I suspect AMD only fixed the later.  

Anyways those saying it did work indicate how many GPU (and/or cards if you have multi GPU cards) you have.  Same for those who don't.  I suspect everyone who says it works has only one card (maybe only one GPU).  Everyone who says it doesn't has multiple GPUs (or maybe multiple cards).  Also include OS.

I'll go:

My system has the 100% bug running 11.9

The newest variant still doesn't fix the bug for me..

I found by express uninstall CCC removes everything, I found that using custom uninstall CCC removes everything except the CCC manager.

If you used custom, you might find CCC manager stuck in programs and features, and cannot remove, throws an error about uninstalling.

If you used custom and find yourself stuck with CCC in Programs and Features, I had to use Windows Install Cleanup program to remove it from Programs and Features. If you try to install a new ATI/AMD driver with that older version of CCC manager, you will have two CCC managers and/or will cause headaches.

Now that is out of the way, and you haven't uninstalled yet, uninstall CCC by using express uninstall.

Download Latest version DriverSweeper-phyxion.net

After uninstall of CCC, boot into safemode and run driversweeper, Driversweeper removes left over residue registry keys and ATI/AMD file/folders. It will ask to reboot, so reboot. You can also run some kind of registry cleaner tool like ccleaner or registry cleaner expert.

Boot into windows regular, install your version of CCC that you want, reboot, on regular boot into windows, re-run the CCC driver setup .exe, install the sdk that is packed with that setup, no reboot is required.

I would avoid everything in the setup except for CCC install manager, AMD Display Driver,MS C++,CCC and for the last AMD APPSDK RUNTIME. Avoid everything else in the setup and you will most likely receive a failed install ect.

Hope this clears up some of the questioning you have.

Installed and it didn't fix my CPU bug , i have two 6870, still didn't try to do driver clean up as some one mentioned here ,
is the cleanup only removing the catalyst from the windows control panel or also from the device manager  ? do i have to reinstall the SDK ?
Thanks guys !

Actual power consumption might differ some but the TDP for the 5750 is just 86 W compared to 108 W on a 5770.

And as for efficiency, I can say that after some comparative testing done by adding and removing my 5750 into my part time mining rig next to my 6850 I got a total system wattage increase of ~108 W (at the wall).I'm not sure how much of that is due to the extra CPU cycles but if I assume negligeable increased CPU power consumption and factor in my power supply's (in)efficiency, my 5750 is using up ~86 W.

That's 86 W while overclocked to 955 MHz and pumping out a nice 200 MH/s. 2.3 MH/J is not exactly garbage in my book.

I'm not good with numbers, but if it's doing 150 to 175 Mhash/s at ~100 watts, that's 1.5 to 1.75 Mh/J, right?

The 5750 was $100 at a local store, and there was a $25 mail-in manufacturer's rebate (HIS brand). A new 5750 was purchased and taken right back: the store kindly applied the rebate price to it plus knocked more off for being "used", so I got to purchase it for extra cheap.
I used it to upgrade an old system that had an 8600 GT (6 Mhash/s).

Don't let the hate get to you.  I'm not sure what the wattage is on a 5750, but on a 5770 it's about 2:1 mh/j.  They're small but stout.

Really? $55 for a card that gets 175 Mhash/sec seemed pretty nice to me. It turned an old box of mine into a nice miner for cheap.

Still bugged for me
