Only with GPU.

Does 2.60 not leak shares to backup pools anymore?

Also e.g. on linux you can:
echo -n "gpuintensity|2,8" | nc 127.0.0.1 4028 ; echo
echo -n "gpumem|2,250" | nc 127.0.0.1 4028 ; echo
echo -n "gpuengine|2,900" | nc 127.0.0.1 4028 ; echo
N.B. YMMV
That's an interesting way of fixing it up. echo -n "gpuintensity|2,8" | nc 127.0.0.1 4028 ; echo
echo -n "gpumem|2,250" | nc 127.0.0.1 4028 ; echo
echo -n "gpuengine|2,900" | nc 127.0.0.1 4028 ; echo
N.B. YMMV
I haven't used the API yet but I may try that as a workaround for now.
Thx.
edit:
Yup. That worked nice.
I added it to my startup script as a background job with a small time delay.
It's odd that using the API works but conf settings don't.
Thx again.

I had a GPU hang/crash long ago that seems to have damaged one of my 3 GPUs.
After that crash I could never get cgminer to auto set the intensity, engine and memory speeds on this one GPU (though the other 2 are fine). I can omit the values for the 3rd GPU in cgminer.conf and cgminer will start that GPU fine with defaults I=4, M=1000, E=800.
After that I can manually use the screen to set I=8, M=250, E=900 and it will run great.
But always, always if I try to put those same values in the conf file and have it set them upon starting it always hangs the machine. I'm a bit tired of manually setting the values whenever the machine restarts.
Anyone recognize why this happens or ideas how to fix?
(btw that GPU is more fragile too. It won't run as fast as the others. It used to need a small voltage bump to even come close.)

Then have something that runs after it's ready:
java API "gpuintensity|2,8"
java API "gpumem|2,250"
java API "gpuengine|2,900"
Obviously the script you have those 3 commands in and how you run it will vary depending on OS and OS version.
Also e.g. on linux you can:
echo -n "gpuintensity|2,8" | nc 127.0.0.1 4028 ; echo
echo -n "gpumem|2,250" | nc 127.0.0.1 4028 ; echo

Check the new readme included it has lots of information. Try --shaders 2048 and -g 1 to begin with, then slowly increase -g if it doesn't crash.
Sure! I've read that... And played with those numbers, always same result...
I'll try a old cgminer-2.5.0 compiled from git that I have in some flashdrive around here, it was working before... I was getting +500kH with this same 7970 card... Same drivers/sdk/etc...
Thanks anyway!
Cheers!

New release - version 2.6.0, July 29 2012
- Limit total number of curls recruited per pool to the number of mining threads
to prevent blasting the network when we only have one pool to talk to.
This is the fix for those who keep asking if the bug with failover-only mode where it sends out lots of requests has been fixed. But of course, run 2.6.1, not 2.6.0 since that has the silly fake sick bug. - Limit total number of curls recruited per pool to the number of mining threads
to prevent blasting the network when we only have one pool to talk to.

Hi!
I have 1 7970, running cgminer 2.6.1 for Bitcoin smoothly.
When I try it for Litecoin, it just crash...
Even if I halt and start the machine, it doesn't work...
I'm using CGMiner 2.6.1, Ubuntu 12.04 64 bits, Catalyst 12.6 and SDK v2.6.
I appreciate any help!
Thanks!

I compiled 2.6.1 for Windows and I've got it running now with 2 BFL Singles.
It looks like it tries to restart now if I pull the power plug on the Singles. It's a little touchy if it tries to restart while the BFLs are still booting up (the first time I tried, only one of them restarted). On a second try they both restarted, though.

... and a Xubuntu 11.04 executable in my github downloads:
https://github.com/kanoi/cgminer/downloads
For anyone who didn't realise, it's just the executable file to put in place of 'cgminer'
Nothing else needs changing
First get and extract the full binary release from ckolivas and then copy my file in place of 'cgminer'
Running fine on my 3 setups:
1) 1xBFL (hashing at 873 MH/s)
2) 2xIcarus (hashing at 379.x MH/s each)
3) 1x6950
Edit: and yes I compiled in scrypt support also - the same as cvolivas' binary version
In case anyone was wondering:
CFLAGS="-O2 -W -Wall" ./configure --enable-icarus --enable-bitforce --enable-ztex --enable-modminer --enable-scrypt

New version: 2.6.1 - July 30, 2012
Quick hotfix to prevent devices being labelled SICK when they're really not.
Changelog
- Remove the low hash count determinant of hardware being sick. A low hash rate
can be for poor network connectivity or scrypt mining, neither of which are sick
devices.
- api.c poolpriority changes
- Display scrypt as being built in as well.
- Fix build warning about KL_SCRYPT when built without scrypt support.
- Documentation updates.

No, they're incompatible, hence the version number update...
Damn, guess I'm stuck with Diablo then.

I left my old phatk .bin in the folder from 2.5, but every time I start 2.6, it generates a new one anyway. Is that supposed to happen?
Oh and it looks like dynamic intensity is fixed again. Sweet.
Yep - they have new date stamps in the *.cl filenames ...Oh and it looks like dynamic intensity is fixed again. Sweet.
