It happens to Linux users too. And it happens with NVIDIA cards. So it's a bit more complex than "Catalyst is doing this". I STILL suspect something weird in the OpenCL kernel or the way it's being executed.

Linux lovers will accuse you of great blasphemy and badspeak for this. I am constantly told of the Linux mining utopia.

I wish them good luck with accusing me of blasphemy when I've been using Linux as my primary OS longer than many of them have been alive. Grin

in win the only work around ive come to so far is under clocking and core affinity. if only you could throttle a core or process's usage to keep the heat & cpu fan down...

yes it is not specific to any drivers/sdk version, normally occurs with windows and >1 card/gpu

Trying out the 11.7 preview drivers:

When I mine with 3 GPUs, I have 3 CPU cores running 100% and good hashrate.
When I mine with 4 GPUs, I have almost zero CPU-load and hashrate is 3-5% below normal.

Anyone else seeing this?
I'm on 64-bit Windows 7.


Sure that isn't a PSU issue?

Yes. It is happening to many Windows users regardless of PSU.

Egh.. Sounds like the insanity will continue. Though I'd have to say I would buy an extra card and lose 3-5% hashrate for near-zero CPU-load right now.

100% CPU will cost you additional power bill so that's actually a reduction in mining profit (or mhs)

If you stop your guiminer via remote desktop, it'll stop seeing opencl. Cannot restart mining because of that...

100% CPU is really annoying. Just added second card - now I have that... Tried using SDK 2.1 - hash rate was total shit and it was still using 100% CPU Sad

verified remote desktop works (although MSI afterburners still doesn't show up the card in a remote desktop session). 100% CPU is annoying. So downgrading it to Catalyst 11.6 + SDK 2.1

Despite the version of your driver, don't use CrossfireX - use those dummy plugs; those little bastards need to survive!

I might be blind... I see 11.7 all over but I can't find a direct download link? I want to try to get some of this fabled performance increase.

Hmm, interesting. I already have tons of dummy plugs but it'd be nice not to have to worry about such things in the future. I'll give 11.7 a whirl later today and report my findings Smiley

I look forward to that. Also, are you using the release candidate or am I somehow missing the full version download?

I'm running 11.7. Runs fine minus the CPU issue with phoenix. Very stable and does eliminate the need for a dummy plug. Found out about 11.7 minutes after I ordered 20 resistors. Smiley

Ouch, at least they're cheap, I guess.

$2.50 for 20 68ohm resistors, shipped. Whatever. Smiley

Re: 11.6B, I've had issues with phoenix using 50% of my CPU PER GPU. The fix is to set affinity to just one core. It'll use 100% of it but that will minimize other cores being used.

I believe 11.6b also does away with the needing dummy plugs...

http://support.amd.com/us/kbarticles/Pages/AMDCatalyst116bHotfix.aspx

Just tried 11.6B and now both OpenCL and Phoenix use 50+% of my CPU in GUIMiner. Previously only Phoenix had been eating up my CPU resources... I heard this is a common error.

Sadly I don't know anything about that, haven't had any issues so I had not read into solving it.
