just what is "intensity"?

Did you see this?

--intensity|-I Intensity of GPU scanning (d or -10 -> 10, default: d to maintain desktop interactivity)

and what does that mean? how does it affect miner output?

GPU-README (yeah another of the files people don't read)

INTENSITY INFORMATION:

Intensity correlates with the size of work being submitted at any one time to
a GPU. The higher the number the larger the size of work. Generally speaking
finding an optimal value rather than the highest value is the correct approach
as hash rate rises up to a point with higher intensities but above that, the
device may be very slow to return responses, or produce errors.

NOTE: Running BTC intensities above 9 with current hardware is likely to only
diminish return performance even if the hash rate might appear better. A good
starting baseline intensity to try on dedicated miners is 9. 11 is the upper
limit for intensity while BTC mining, if the GPU_USE_SYNC_OBJECTS variable
is set (see FAQ). The upper limit for sha256 mining is 14 and 20 for scrypt.

well, the intensity was set a -1 on the little machine that i am playing with. moving it to 5 raised the hash rate from 6Mhash to 10Mhash. moving it to 6 looked like it caused the rate to drop a little, so 5 it is.

I tried to setup cgminer 3.1.0 with the simpliest settings

cgminer.exe -o http://pool:port -u username -p password -scrypt

Try --scrypt instead of -scrypt

I AM AN IDIOT!

i think i can figure it out an post the result here.

Having big problems with cgminer 3.1.0 on windows 7 64 bit.

Using HIS HD 7970 x2 with catalyst driver 13.1

Direct 3D 9.14.10.0945
OpenGL 6.14.10.12002

I tried to setup cgminer 3.1.0 with the simpliest settings

cgminer.exe -o http://pool:port -u username -p password -scrypt

Cgminer directly crashes with the windows screen, that the programm is not working any more.

I have absolutely no idea what i can do :/

The HIS control center is installed too, should i deinstall?

I recently changed from nvidia to Ati card.

Hy,

i have a Sapphire 7970 and try to mine LTC but i come in the best case to 400 to 500 kh/s has anyone an idea what i am doing wrong?

First i was on Sabayon 11 Linux with the amd beta driver 13.3 and sdk2.8 somehow i managed to change the driver to 13.4 and also tried sdk 2.7 no change.
Once i started to try other drivers like 12.10 my system crashed totally, right now i switched to xubuntu 12.04, with sdk 2.6 but still with very low kh/s

when i try to change the engine clock and memory clock it has more or less no effect at all, kh/s does not really increase or decrease, the only effect is that at some point th gpu crashes and thats it.

with these options i start, which do bring the best result so far
--scrypt --auto-fan --temp-target 70 --intensity 13 --worksize 256 --thread-concurrency 22272 -g 2
Another question i have is, when i change the sdk and or driver, do i need to recompile cgminer or can i use the same binary?

thanks a bunch for any help.
cheers

Hei!!

I am having strange problem. I use CGminer 2.11.3 and on my 5970 I do not have a display after starting to hash. On the pool site I have a output for khash / s but I cannot see and change anything on the fly in CGminer.

Has someone an idea, what could be wrong?

Tnx in advance ...

Is it possible to use cgminer with HTTP proxy that have username and password autentication?

Yeah there was a time when we could ONLY use 1 11.x driver.

If the driver is broken for mining, what do you expect cgminer to do about it?

no idea, its why I asked. Despite what my search said, I couldnt be the first one with the problem. I was genuinely hoping for a workaround or fix I missed.

The readmes go to great pains to say many times over that drivers and sdk are everything. I really wish people would pay attention to documentation.

updated to catalyst 13.4 from 13.1 last night. now cgminer (301 and 310) hangs on start. i get as far as this:

Code:

[2013-05-03 16:18:35] Started cgminer 3.0.1
[2013-05-03 16:18:35] Loaded configuration file cgminer.conf
[2013-05-03 16:18:36] Probing for an alive pool
[2013-05-03 16:18:37] Disabling extra threads due to dynamic mode.
[2013-05-03 16:18:37] Tune dynamic intensity with --gpu-dyninterval
[2013-05-03 16:18:37] Network diff set to 10.1M
[2013-05-03 16:18:38] Thread 1 being disabled

and it just sits there indefinitely. tried a few different .conf settings, and get ther same. without a .conf and specifying url and such, it crashes a few seconds after hitting return after entering password.

any ideas?

nobody? I'm to the point where im mining with guiminer, seeing ~150Mhs slower than i should be Sad

Read your first line ... that a hint?
Downgrade.

Yeah, I was hoping for an actual solution rather than just reverting and ignoring the problem.

Well I tried to search for this but came up empty. Currently solo farming for feathercoin when I see this:

Code:

Rejected 000001f9 Diff 8.49M/5432796 BLOCK! GPU 1 pool 0

What does this mean? I solved for higher than the current diff. Did some one else beat me to the punch?

If blocks come in quickly on your altchain, and you were mining solo on your *coind then it doesn't have a way of telling you blocks have changed (like longpoll or stratum), so you risk mining on old blocks and increasing rejects. Lots of ways to improve this, someone else might have time to tell you.

Thanks for the reply. I wondered if it was something like that. Must've been bad luck because I actually put in a second pool to get the longpoll... must've missed it by that much... Thanks for the great app

Its like priority in the windows task manager, it sets how important the hashing is to the GPU. 'd' setting is good for computers being used while mining, while most dedicated mining cards see performance benefits in the 9-15 intensity range, from what I've seen.
