Been having random crashes ever since I upgraded to 2.9.5 from 2.4.x. My install is 1½ years old Ubuntu 11.04, with 11.6 drivers and 2.4 SDK I believe. Runs fine for a day or so, and this happens on both a 4x 5970 machine and a 5x 58xx one.

It screws up the screen output a bit when it crashes, and looks like this:
Any ideas? Should I just downgrade back to 2.4 as that seemed to work, I mainly updated due to stratum but I suppose that's not really necessary atm.
Absolutely do not downgrade please. Are you running with a pool, backup or otherwise, with GBT at all? There is still one bug when mining on GBT which is only fixed in git. Alternatively run a debug build with core dumps enabled and get a backtrace if you know how.

Sorry, I'm pretty much clueless around linux/cgminer Sad

Primary pool is eclipse (GBT), secondary is btcguild with Stratum.

EDIT: It seems git has a newer version, will try if that helps.

Yes please try the git version then since you have a gbt pool. I also recommend connecting to EMC's stratum pool instead.

New version - 2.9.6, 2nd December 2012

Minor bugfixes.


Human readable changelog:

Fixed further crashes with GBT mining.
Scrypt mining now shows more of the relevant hash portion and higher diffs than just 65.5k.


Full Changelog:

- Make gen_stratum_work more robust by using a dynamically allocated array for
the header in case bogus data is sent by the pool to avoid overflowing a static
array.
- scrypt_diff now returns a uint64_t
- Support monitoring and reporting much higher diffs for scrypt mining,
truncating irrelevant zeroes from displayed hash.
- Pass ostate values around in scrypt to be able to extract full hashes if
needed later on.
- Since we will be using calloc_str to put a string into it, convert the
function to calloc_strcat which does it automatically.
- Revert "Handle crash exceptions by trying to restart cgminer unless the
--no-restart option is used."
- Count longpoll and GBT decodes as queued work since the count otherwise
remains static.
- Use the string helper functions to create gbt blocks of any length.
- Provide helper functions calloc_str and realloc_strcat to create and extend
arbitrary length arrays based on string length.

cut/paste ...

2.9.6
An Xubuntu 11.04 x86_64 executable is in my github downloads called cgminer-2.9.6a
https://github.com/kanoi/cgminer/downloads
(it also works on Fedora 16 and 17)

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'

No problems so far on my GPU or 'BFL+2xICA'

Since I'm no longer GPU mining, I just run it for a while on my single 6950 to see what happens
- the other 6950 is waiting to play minecraft with my kids Smiley

BFL+ICAs (1.6GH/s) on OzCoin Stratum with fixed 8 diff

(MMQ is ... still ... doing new code testing)

The same configure options as cvolivas' binary version
In case anyone was wondering:
CFLAGS="-O2 -W -Wall" ./autogen.sh --enable-icarus --enable-bitforce --enable-ztex --enable-modminer --enable-scrypt
make clean
make

Alright, I will try stratum, because I still had a crash just now with the newest 2.9.5 git version. I suppose 2.9.6 doesn't include additional fixes since my yesterday's post?

Anyways, hopefully stratum will help.

--gpu-fan <arg>     GPU fan percentage range - one value, range and/or comma separated list (e.g. 25-85,85,65)
--gpu-map <arg>     Map OpenCL to ADL device order manually, paired CSV (e.g. 1:0,2:1 maps OpenCL 1 to ADL 0, 2 to 1)
--gpu-memclock <arg> Set the GPU memory (over)clock in Mhz - one value for all or separate by commas for per card.
--gpu-memdiff <arg> Set a fixed difference in clock speed between the GPU and memory in auto-gpu mode
--gpu-powertune <arg> Set the GPU powertune percentage - one value for all or separate by commas for per card.
--gpu-reorder       Attempt to reorder GPU devices according to PCI Bus ID
--gpu-vddc <arg>    Set the GPU voltage in Volts - one value for all or separate by commas for per card.
--intensity|-I <arg> Intensity of GPU scanning (d or -10 -> 10, default: d to maintain desktop interactivity)
--kernel|-k <arg>   Override kernel to use (diablo, poclbm, phatk or diakgcn) - one value or comma separated
--ndevs|-n          Enumerate number of detected GPUs and exit
--temp-hysteresis <arg> Set how much the temperature can fluctuate outside limits when automanaging speeds (default: 3)
--temp-overheat <arg> Overheat temperature when automatically managing fan and GPU speeds (default: 85)
--temp-target <arg> Target temperature when automatically managing fan and GPU speeds (default: 75)
--vectors|-v <arg>  Override detected optimal vector (1, 2 or 4) - one value or comma separated list
--worksize|-w <arg> Override detected optimal worksize - one value or comma separated list

What are the best flags to use for ATI 5830?

I'm only using -w 128 and I-9 right now, any others?

I'm only getting 210 MHash, but before when I was using phoenix I was getting 270 MHash

Try this:

--auto-gpu --auto-fan --gpu-memclock 300 --gpu-engine 600-900 --gpu-fan 25-80 -k phatk -v 2 -w 256 -I 9

I thought -w 128 is best for 5xxx cards, not 256?

I always had good luck with 256 on SDK2.5. I believe those using 128 were using SDK 2.1. Try both and see what you get!

It takes about 24 hours for the hash rate to fully stabilize, additionally, for ozcoin use the address http://stratum.ozco.in:3333 to gain the benefits of stratum over LP.

It may also be network issues between your location and the server.

I've got 4  5830 cards mining on 1 PC

Before I switched to cgminer each was getting 270 MHash

Now with cgminer, and only using -w 128 and I-9 flags, 3 miners are getting normal MHash but when I start the 4th miner it's only getting 150 MHash

Any idea why?
