If you set the 7950 to dynamic intensity mode, you will be able to game without a problem without needing to disable it.

How do I set up dynamic intensity mode on GPU 0, but leave GPU 1 at 16? (using scrypt) I checked the readme again and nada.

I want to assume it's --intensity 12-16,16 but don't want to try that before asking here.

--intensity d,16
(but I have no idea how well dynamic intensity works with scrypt Tongue

)

Does somebody have similar issues and if yes what can be done to resolve them?

And as always it happens at night:) I know that it can happen randomly but never during day Sad

I run my cgminer in a loop
http://pastebin.com/Z4pG26uF
(my cgminer is just another script 'cgminer.sh' that runs cgminer with the options I want)

Thus if it ever crashes, it leaves a core and then restarts

Do something like that - if it actually crashes - so it just restarts (with a 5 second sleep)

Obviously, in my case, I certainly want this to help find bugs and help with fixing them
(so I also compile -g and without -O2) but yeah it makes it easy to find bugs and also keep mining

Is this something that can be done in windows 7 64bit? whit some program/scripts that loop and restart would be great..........When cgminer stop mining for some reason..........pool or others...........
Also i use task manager to set priority 2 real-time. ist there a permanent way to do that?

i have C:\cgminer\cgminer.exe

anyone know? i can offer 2btc for working solution

PS you are doing great work kano & ckolivas

Thanks to dlasher, SAC, burger, and especially ckolivas and kano; my BFL single is now running on my R-Pi! Soon I will re-post dlasher's guide with the corrections I used to make it work for me. (First I will test with a fresh Raspbian install.)

Is there a way to make mining on a PC that has a AMD 7950 and Intel HD Graphics possible?

My Motherboard is a Z68, I would like to connect 1 or 2 Computer Displays to the HDMI and DVI on Z68 motherboard and 1 or 2 displays to my AMD 7950.

When I start Cgminer it says too many gpus or something along those lines.

Yes there is, but you will need to use a combination of parameters to these options: -d, --remove-disabled, --gpu-platform and --gpu-map. Start with 'cgminer -n' to read what cgminer finds and then read the advanced section on gpu-map in the readme.

So this allows me to use the 7950 to mining when it's not doing much in windows 7?
I can have 2 displays connected to 7950 and 2 displays connected to Z68 HD3000 and just before I start gaming I just disable 7950 in cgminer?

Obviously primary display in windows 7 needs to be connected to 7950 so that games start on 7950.

If you set the 7950 to dynamic intensity mode, you will be able to game without a problem without needing to disable it.

Ok if you need the HD7950 for gaming you can't mine on it at the same time without a noticeable lag. Disable lucid MVP and connect a cable to your mobo and then use just HD3000 for gaming. Mine on the 7950.

Thanks for suggestion but I do not want to game on HD3000, I want to mine on the 7950 only when I'm not gaming (I'm not gaming 90% of the time.)

When compiling you need the development package of the library when it is not found so...

Code:

apt-file search libudev.h
libudev-dev: /usr/include/libudev.h

Thanks but that did not work for me:

Code:

root@raspberrypi:/usr/src/cgminer# apt-file search libudev.h
bash: apt-file: command not found

- The linux n00b

Edit: I hope this is not too off-topic but I believe it will be useful for other (n00b) users to get cgminer working on their Raspberry Pi. Or at least those that want to compile from source. Now that I think about it, didn't someone offer pre-compiled binaries for the RPi? Or was that for one of the Bitcoin clients???

can't you just do:

Code:

apt-get install libudev-dev

Never built on that - but the ./autogen.sh should work that way fine with 2.7.6
I guess there's more to getting it working - you'll need to ask P_Shep I guess?
He seems to get it working on the usual hardware

While I see r-pi listed in the subject, I see no instructions or downloads provided. Am I missing something?

For Raspbian, my steps went something like this:
<... snip ...>

Thank you VERY much for this guide. I did encounter a problem with this step:

Quote

root@raspberrypi:/usr/src/cgminer# bash ./autogen.sh --enable-scrypt --enable-bitforce --enable-icarus --enable-modminer --enable-ztex --with-libudev
Running autoreconf -if...
Configuring...
configure: WARNING: you should use --build, --host, --target
configure: WARNING: invalid host type: --enable-modminer
checking build system type... Invalid configuration ` --enable-modminer': machine ` --enable' not recognized
configure: error: /bin/bash ./config.sub --enable-modminer failed
root@raspberrypi:/usr/src/cgminer#

Then I remembered I did not need modminer (no HW for me - YET) so I trimmed it down to the command that I needed:

Quote

root@raspberrypi:/usr/src/cgminer# bash ./autogen.sh --enable-bitforce --with-libudev

... and it worked. But then "make all" also failed:

Quote

root@raspberrypi:/usr/src/cgminer# make all
make: *** No rule to make target `all'. Stop.

root@raspberrypi:/usr/src/cgminer# make
make: *** No targets specified and no makefile found. Stop.

root@raspberrypi:/usr/src/cgminer# ls -l M*
-rw-r--r-- 1 root root 2470 Sep 27 20:31 Makefile.am
-rw-r--r-- 1 root root 91117 Sep 27 20:47 Makefile.in

Now I'm stuck. Damnit - I hate being a n00b at new stuff! Wink

Hey Kano,

Yep - thanks. The line doesn't explain the problem - but it shows it's at least in findnonce when it crashes for you - so probably a bug I introduced.

I've also thought of a easy (should have thought of before Tongue

) way to try reproduce it myself.
Add 1 to each nonce value returned should give me LOTS of HW errors to hopefully get the same result.

I'll try sort that out later today - thanks for the info.
If I can't get it to happen I'll ask for more help to run a debug version I'll put up for you.
But I'll let you know first.

Thanks kano, --no-restart worked, you are right, the fan reading on gpu 3 fails, even though
all three cards are 5970s, so there is actually just 1 fan on each card..

Strange that it works with card 0 and card 2, but not card 1 ?!

Maybe a BIOS error of the card ??

I actually only have the problem on this particular rig..

here a screenshot:
http://imageshack.us/a/img685/3752/bildschirmfoto20120927u.png

My only guess now, as I mentioned before, you may need --gpu-map
It looks like it not associating the fan with both GPUs ... but I don't have any dual GPU cards so I've no idea other than read the README

I've had few H/W error before also, but cgminer 2.7.6 seems to "freak out" and crashes randomly when a h/w error occurs.

thats not the case with good old 2.4.2, it just counts up the errors

As per the README FAQ ...
Add "-T -D --verbose"
and post a log

However, it's better with a core dump to show exactly where the problem is.
Before you run cgminer:
ulimit -c 2097152

However that won't give much details about where it crashed without:

If you compile it your self, then (as I said 2 pages back):
CFLAGS="-g -W -Wall" ./autogen.sh --enable-icarus --enable-bitforce --enable-ztex --enable-modminer --enable-scrypt
make clean
make

And of course you don't have to include all the options on the end you don't need ...

Once it crashes you'll have a core.nnnn in the directory
where nnnn is the process number.
Find it with
ls -ort core*

Then:
gdb cgminer core.nnnn
bt

and bt will tell you where it crashed ... to add to the pastebin

~~Edit: however, with that many errors, it's likely to just be in the ATI driver and you probably need to clock it down more?~~
Nope - it doesn't look like it's lots of error in the HW: counter ... anyway as above ...

Weird, I've been getting HW errors after upgrading to 2.7.6 also. I thought my GPU was on the way out because I've never gotten any before.
