11.6 (or 11.9/11.10) are fine if i am right
Topic: could someone who is not a newbie repost please (Read 651 times)
Try the Catalyst 11.06 version
http://www2.ati.com/drivers/linux/ati-driver-installer-11-6-x86.x86_64.run
This is the latest version that doesn't suffer from the "100% CPU use bug"
Also check out(if you haven't already seen it)

Hope this helps, I see that it as a few of weeks old. Good Luck!

Hi. I am new to the forums but not new to bitcoin mining, win, linux, programming, etc. Any change at a promotion so I can post this myself? If not,
please repost this in the thread: poclbm using CPU 100% even though using GPU?
I have some relevant information here that has not been mentioned yet. I am running identical mining rigs and had a mobo failure and replaced it. both HAD an asus p5k se (read-- cheap) motherboard with miners running sdk 2.1 and catalyst 11.7 for linux (on ubuntu 11.07). replaced dead mobo on miner2 with a gigabyte GA-EP43T-UD3L figuring I could upgrade a little. kept same processor, same GPUs, just upgraded mobo and ram to go with it. now miner2 takes 100% of a core per GPU running. EXACTLY the same everything else. Upgraded to sdk 2.4, reverted to sdk 2.1 and upgraded catalyst 1.8, still no improvements. Tried all these configurations on both poclbm and phoenix miner.
I think the problem is motherboard specific. the gigabyte mobo has 5 pcie slots in total, so I think it may have something to do with the way the Catalyst driver interacts with the south bridge architecture on more advanced motherboards.
Basically, this is solid proof that if it's not working, even on linux, it's not because something is configured wrong, we basically just have to wait for an AMD update.
on a related note, it's ironic that the $10 refurbished mobo from ebay is the one giving me the best performance. heh.
