I'm not getting any better performance, just higher temps and snarky support. Back to phoenix I go, where my card runs full out without melting.

You do understand the temp rise is simply an indication that cgminer was working the card slightly harder.  Nothing more.

I mean if you reduced the chip's clock by 2% to 3% then temps would fall would you consider that superior also?
Likewise if every time a round was finished cgminer idled for 2% to 3% of the round time temps (and hashing performance) would fall would that be a superior product?

cgminer is simply a more efficient miner.  It drives a card as hard as it is possible w/ very little wasted clock cycles.  If you want lower performance you can always lower clocks or intensity but it seems stupid to consider the less efficient miner to be superior because it is less efficient. Huh

All that extra heat is coming from somewhere. Since I believe in the laws of physics I would have to say it is using more electricity.

Not necessarily. Temperature sensors are in particular places on the GPU. The heat is relatively local.  Moreover, the default sensor is IOdisp, which is not the same as the sensor in shaders and the difference can be substantial (+-10C easily). THe only way to know for sure if one miner uses more electricity than another is by measuring power consumption. Temperature is a very poor proxy for that.

being able to keep my rigs quieter with auto temperature management is a godsend, and it mines faster than phoenix. what was the problem again?

works as designed for me

I guess if a person cannot use the software he is better using something he can...

Thanks for the tool ckolivas... it's beautifully functional and keeps my temps exactly where I put them Wink.

Seriously if you don't want to run your GPU flat out, decrease the intensity... but this is the most bizarre complaint yet about cgminer, that it extracts more out of your GPU.   Huh

Errr... yeah, it can be done, but i think you're missing the point... heh
I just tested with an atitweak of a fixed CPU % (47%) on the .sh starting cgminer.

Phoenix: 69.5C
CG: 75C

Same settings, same fan speed.

CG does make an extra 4Mh/s, but if the 'price to pay' is an extra 5.5C, then it's kinda.. not worth it.



[G]PU management->[C]hange Settings-> [A]utomatic
Make sure fan autotune is enabled, if not, hit [F]an auto to turn it on, hit [A]utomatic again
Hit [T]arget type 70, press enter

Problem solved
To save settings, return to the main menu (any key not reserved by a command, I use space), [_S_]ettings->[W]rite config file

Edit: [_S_] instead of strikethrough

Okay, I'll bite... why?

All that extra heat is coming from somewhere. Since I believe in the laws of physics I would have to say it is using more electricity. The heat isn't coming through my internet tubes. It also reduces the lifespan of my video cards.
Um... that's like the argument of "use a lower power card".

I was feeling generous, so I thought I'd quote from the grossly underused readme...


AUTO MODES:
There are two "auto" modes in cgminer, --auto-fan and --auto-gpu. These can
be used independently of each other and are complementary. Both auto modes
are designed to safely change settings while trying to maintain a target
temperature. By default this is set to 75 degrees C but can be changed with:

[snip]

Fan control in auto fan works off the theory that the minimum possible fan
required to maintain an optimal temperature will use less power, make less
noise, and prolong the life of the fan. In auto-fan mode, the fan speed is
limited to 85% if the temperature is below "overheat" intentionally, as
higher fanspeeds on GPUs do not produce signficantly more cooling, yet
significanly shorten the lifespan of the fans. If temperature reaches the
overheat value, fanspeed will still be increased to 100%. The overheat value
is set to 85 degrees by default and can be changed with:

Set the temp down then?

This... cgminer allows you to set a target temperature if you have ADL support.  Probably your target is higher, so it runs the fan less.

My GPU temps went up 5C when I switched from phoenix to CGminer. Any reason for this?

Before anyone says that you're imagining things... yeah, mine did, too. 5C on one, 6C on another.

having an issue with trying to use multiple gpu-engine speeds. i have a rig with 3 5870's and one 5970.

GPU 0 is 5870
GPU 1 is 5870,
GPU 2 is 5970
GPU 3 is 5970 - obviously from same card above
GPU 4 is 5870

I want to clock the 5870's at 950, 900 if they're not stable enough. I want the 5970 at 800 or 820 if I can get it.

memclock of 300 for everything.

So this is what i wrote at first.

./cgminer -o http://miningpool:port -u (username) -p (password) -I 9,9,9,9,9 --gpu-fan 85 --gpu-engine 950, 950, 820, 820, 950 --gpu-memclock 300

I just got a 100% cpu bug out of it.

Any thoughts or suggestions?
Not sure, but that looks like a space after each ',' in --gpu-engine that shouldn't be there.
