i redownloaded and got the same error as above.
my command to run miner is :
GPU_MAX_ALLOC_PERCENT=100 GPU_MAX_HEAP_SIZE=100 ./mmc-miner MNafBQWjxf6t2moSuRbpUkG7Uo8m8twWwX
I have another update, would you please try again? (I am trying options that are likely to help blindly as I do not have hardware to test myself, my apologies if it bothers you).

I duplicate that most recently reported error with my R6670 card on Ubuntu 12.04.

But the card is a wimp for mining anyway, I discovered mining scrypt on Windows with it . . . finding a better option :)

hi friends when i try to run miner on ubuntu 13.10, i got following error, does anybody know what the cause is?

Hi! I have made a typo which prevented miner from starting on 2G cards, it is fixed now. But also for many people here the miner does not work in Windows on 6xxx and 5xxx platform. Would you please redownload it from the same place, try it again and tell us if it works now and if you get anything but rejects from the pool?

Check the temperature with:

Code: [Select]
aticonfig --adapter=0 --od-gettemperature
and fan speed with

Code: [Select]
aticonfig --pplib-cmd "get fanspeed 0"
If the temperature is too high, try setting the fan speed like this:

Code: [Select]
aticonfig --pplib-cmd "set fanspeed 0 80"
In Windows world they have all those fancy GUIs ;)
my problem is I get
PPLIB command execution has failed!
ati_pplib_cmd: execute "get" failed!

and with cgminer i have no problem with these cards runing at 70% fan speed with 76 degree
thanks for all your help!!

could you add an option to control the vents rotation on card

thanks in advance
Perhaps, in future versions. Driver's autotune might work just as well in most cases: card's cores are not always loaded to 100%, during periods when most time is spent accessing memory, cores have a chance to cool down.

thanks a lot I fear only that 94 degree ist too hot for my 290
Some people have reported a much cooler operation than with scrypt, and a lower power consumption.
yes you are right on my saphire its 67 but on ASUS card its 94 which is very sad
Figure you have to check its fans and thermal grease.. 94 is not healthy at all.

does anyone know why it takes so long to load block index?
I haven't had this happen to me before.

Hi,

Are there any flags I can add to the .bat file to maximise hpm for my 7950? Sorry if this is a nooby question.
Short answer - no. You can only try overclocking, but the algorithm is not tunable by its design.

Thanks for the quick response. Does the algorithm favor memory clock speed?
It depends on both core and memory clock. Like with scrypt, there is a sweet spot you could find tuning both frequencies (but not the same one as for scrypt). In case you wonder, for my 7870GE it is 1080/1250.
