Can cgminer set GPU/MEM frequencies out of BIOS ranges? For example, something like MSI Afterburner in Windows can do?

cgminer uses ADL (AMD Display Library, written by ... AMD)
If ADL can't do it, cgminer can't do it.
The expected answer to your question is 'no'

I would love to see an expanded version of this that goes down to 100 (or lower) memclock using latest version of cgminer, latest drivers, and SDK 2.1.

Here is some tests

Wow, now that are very nice graphs ... it would be so cool, if you could add the diakgcn kernel into that (-k diakgcn). Not because I think it is faster, but it would be great to know how it performs in comparison to the other available kernels.

kano,

intensity has an even bigger influence than CPU speed, at intensity 'd', same 800 MHz CPU speed, cgminer uses around 50% CPU time

Code:

...

spiccioli

Actually - logically as the intensity drops, the CPU must increase.

When the intensity goes down, it means the work is broken up into smaller pieces.
More pieces means more CPU processing and transferring for the same amount of hashes.

I run 2x6950 on a 3.07GHz i3 CPU running at 1.2GHz and -I 9 and get ~2% CPU (hmm 2 seems low - I would have guessed 5 ...)
(that % number means of a single core in linux coz if you e.g. have 2 cores - total is CPU 200%)
So it's not totally surprising getting high CPU use with 5 GPU's and low power CPU and lower intensity.

You sir, are full of awesome. Will we be able to see the other test results soon?
Do you have a 5870 to test with?

@tenzor Were you running this on linux? And are you willing to share the script you used to generate these results?

So either my CPU is too weak to handle 5 GPUs or cpu usage can be lower, but it does not depend on catalyst/amd sdk.

BTW I've tested catalyst 11.12 (11.11 gives problems installing) and 12.1 on xubuntu 11.10 64bit this morning with more or less same levels of CPU usage.

While it's running at 60% CPU ...
cat /proc/cpuinfo

Note it says CPU MHz 800.00 so I think I've being chasing the wrong problem for two days, if CPU is at 2.8Ghz cgminer uses around 10% of CPU

Thanks for your help!

You could simply try another kernel, as there are 4 of them Cheesy

. Have you installed the latest NVIDIA drivers?

Add one of this switches to your command line:

-k diablo
-k diakgcn
-k poclbm
-k phatk

Dia

Thanks for the tip. Drivers are up to date, and I tried all 4 kernels. On all 4 kernels, the display driver still crashes immediately.

Code:

cgminer -o http://localhost:9332 -O user:pass -d 0 -k (kernel)

If I run the poclbm executable from the guiminer package, it seems to work just fine. GPU is pegged and things appear to be running at ~25M. Guess I'll just do this for now and wait a new release of cgminer.

Is there anything I can do to actually help figure out what's happening?

Thanks,

-Prayer

Lets start simple.
Delete (or move) any bin files in cgminer folder.
Return all cards to stock.
Don't run any third party utilities (Trixx, AB, Catalyst Control Center). If they are set to run at boot change that temporarily.
Do a reboot try running cgminer with code above. Does it still crash? Is so well then you stumped me.

If not then you have a starting point.

The only two things I can think of is
a) cgminer is very efficient. It pushes a card harder than other miners at a given clock thus you can't always run same clock. What matters is MH/s (or more directly shares/min) not clock so cgminer can still be the best miner
b) you got some other junk utility like afterburner which is causing a conflict.

It would be interesting to know, if any .bin files are generated at all ... perhaps it's a compilation issue with the OpenCL compiler.
You could try to add -v 1 -w 64 to force no vectors and worksize of 64 (perhaps CGMINER autodetection messes something up), I guess this should be save on NVIDIA, but I have really no mining experience with their GPUs.

How about doing a search of queue_request inside cgminer source code?

Code:

static bool queue_request(struct thr_info *thr, bool needed)
{
(...)
	applog(LOG_DEBUG, "Queueing getwork request to work thread");

	/* send work request to workio thread */
	if (unlikely(!tq_push(thr_info[work_thr_id].q, wc))) {
		applog(LOG_ERR, "Failed to tq_push in queue_request");
		workio_cmd_free(wc);
		return false;
	}
(...)
}

Some nVidia-specific bug? The hash rate is obviously bogus, it looks as if the kernel failed to perform some check and treated garbage as valid shares. Which kernel did you try?

Hi,

I don't know if this is the correct forum where ask my question, but since it is cgminer related I start from here

I've got a five 5870 rig I've just set up, it runs xubuntu 11.10 with catalyst 11.8 (the one that installs using xubuntu proprietary drivers applet) and I've installed AMD SDK 2.4.

If I don't use GPU_USE_SYNC_OBJECTS=1 CPU usage goes to 90%, If I use it, on the other hand, cgminer uses from 20 to 35% of CPU and CPU is a sempron 2.8 Ghz

Dud catalyst driver. Use 11.6 or 11.11+ on linux.

Sorry ckolivas,

but there is something else, I've just reinstalled everything using kano recipe, now I have xubuntu 11.04 64bit, catalyst 11.6 and AMD SDK 2.4

without GPU_USE_SYNC_OBJECTS=1 either cgminer 2.1.2 or 2.3.1-2 use around 90% of CPU, with sync objects they're around 30-40% with 2.3.1-2 using around 5% more than 2.1.2

So either my CPU is too weak to handle 5 GPUs or cpu usage can be lower, but it does not depend on catalyst/amd sdk.

BTW I've tested catalyst 11.12 (11.11 gives problems installing) and 12.1 on xubuntu 11.10 64bit this morning with more or less same levels of CPU usage.

If you're using linux + git, try the current git tree please to see if it fixes it.

Worked like a champ. Thanks very much! Sent a couple coins your way.

Thanks for testing. I'm considering wrapping up the few minor changes since 2.3.1 and releasing 2.3.2 before I take my break. Likely the only people who would notice a difference are those with twin GPUs going from 2.3.1-2 to 2.3.2. I'm not making any changes that might break something at this moment in time.

What do people think? Should I bother?

A fix that work is a fix no one cries for during your break

. I hope you accept my last pull-request befor the break, anything wrong with it?

I tried this but the engine clock on the first gpu get stuck at 850. That's the stock speed for the card, the other clocks get changed correctly. If I change it from within cg miner it works.

"auto-gpu": true,
"auto-fan" : true,
"gpu-engine" : "600-850,800-800,800-800,800-800,800-800",
"gpu-fan" : "100-100,0-85,0-85,0-85,0-85",
"gpu-memclock" : "150,150,150,150,150",
"temp-target" : "80,70,70,75,75",

You're telling it the upper limit for gpu engine is 850 or 800 depending on the card, so yeah it's listening to you.

gpu 0 should drop clock speed below 850 if the temp reaches over 80. How would you have written it?

Your settings are fine for that. The threshold where clockspeed goes down is 3 degrees over the setting (see temp hysteresis) to prevent the clockspeed being changed too easily when it takes a few seconds for the fans to catch up.
