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

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

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

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.

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.

Sure that isn't a PSU issue?

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

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.

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...

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
