Some one please please please please try granola & see at least it reduces your CPU.
Please please try.

So this hasn't been resolved in the slightest ?

All my PC do that.

with my i7 920, I get 38% load, went into task manager and there was an svchost that was taking 13% that I close, and I put affinity to CPU0 to both my miners and they share the 12/13% 6/6 or 7/5 or 7/6

I've got the same problem
AMD + one 5850 consume 100% of CPU
Windows XP

I'm using a 5970 in two systems, an AMD Phenom II X2 555 and an Intel i7 920. Both running Stream SDK 2.2 and the intel avgs about 30% CPU load, the AMD is 100%. This hasn't been solved yet? Weird.

Dual core vs quad core with hyperthreading, each instance of poclbm should peg an entire core, so that sounds about right.

It depends on the model. Any combination of HD 6900 will cause the 100% cpu usage, no matter about crossfire or not.
The only woraround is to disable crossfire and have only 1 card plugged to a monitor, start a miner, plug that monitor to the other card, start the miner and so on. Yep, it sucks big time.

Indeed, that is the work around for making the card active in windows. Although, I'm not sure what it has to do with the extra cpu load. Or are you suggesting that this will get rid of the extra load? Huh

I don't mind taking extra steps for windows to make a card active. I do mind the extra cpu load.

Also, does a 6990 cause the extra cpu load?

This is most likely a driver side issue. From what I gather, bridging the cards into crossfire (or having a dual gpu card) will prevent cpu load, even though you are running several instances of your miner.

It's working exactly the other way.

I'm a bit confused.

In which situation does the extra cpu load occur?

a. Two single gpu cards - crossfire enabled (causes too much hashrate fluctuation to be worthwhile)
b. Two single gpu cards - crossfire disabled
c. One dual gpu card - crossfire enabled (can you even run a dual gpu card without crossfire?)

Or does it occur in all of these?

I haven't seen anyone complain about high cpu usage with a single, dual gpu card, but I could have missed it. If it doesn't, why?

I've experienced b. and I could test a. but that would require shutting down my miner and I'm reluctant to do that! Cheesy

i was testing the RPC miner and i see the same behavior. I wonder if the drivers + windows have an issue rather than the software!
anyone else trying other miners?
i was said that in linux the cpu goes down to 20-30%

Are you guys all using -f 1 or some absurdly low -f?
Set -f to something higher and your cpu util will go down (though hashrate will as well)

This isn't the issue.

Using -f1 with a single card will require very little cpu usage, 0-3%.

Adding the second card, regardless of what you put after -f, will result in much, much more cpu usage for each gpu mining. I get 25% per gpu on a quad.

exactly the same issue here!

rig:
intel 430 (one core)
X38 + 1GB DDR3
5970 + 6970 (3 GPU cores total)
drivers 11.2 with SPP and 11.4 beta, no extra SDK drivers are loaded
win7 x86

when i am running one poclbm for the first GPU (whatever that be) cpu is at 1-4%
with the second poclbm, cpu goes 99%!!!!
with the third poclbm, cpu is devided for the 2 last poclbms (48%+48%)
i think, perhaps a bug with poclbm program?

I just spent 2 hours trying to solve the issue by installing different versions of both the Catalyst drivers and the stream SDK- nothing helped.

Combinations I tried:
10.09 + 2.1 SDK
10.10 + the included OpenCL runtime
10.10 + 2.1 SDK
11.2 + 2.1 SDK
11.2 + 2.3 SDK
11.4rc2 + 2.3 SDK

.. and maybe some others. Every combination still used 100% of a CPU core for each GPU core.

Hope this saves some time from others. Any ideas on how to fix the issue are also welcome

Uninstall every ati driver & sdk using some uinstallers like revo uninstaller.
Also never install sdk from stand alone adk package, instead install from driver package.
If you have 5000 series card, install 10.12 & 2.1 sdk.
If you have 6000 series card, install 11.2 & 2.3 APP.

You haven't mentioned what card you have, what OS & how many Mhash/s you getting.
Instead of going express install, go for custom install & install only these 4.
ATI display driver, ATI catalyst install manager, APP 2.3 or SDK 2.1 & VC++

Thank you for the response. I tried this, but still no luck. I'm going to try some wild stuff, like removing some AMD specific drivers etc next.

Hardware specs:

AMD 880G (3x PCIE slots for GPUs)
AMD Phenom II x4 BE550
1800Mhz DDR III
1x Radeon HD 5970 (about to get another one soon)

and I'm running win7 64bit.

I'll post if I figure out something. I need to fix this before I get the other card or this will be 100% of all my CPU core
