@arielbit - With 14.9 driver finally the problem was solved, BUT the hash rate is twice low as yours - my 5850 card (clocked at 780 MHz) shows 15.5 MH/s, and my 5870 ( stock at 850 MHz) - 17.2 MH/s. Any idea what i miss ?
The *.bat file looks like - sgminer.exe --no-submit-stale -k lbry -o stratum+tcp://lbry.pool.mn:8878 -u user.1 -p xxx -I 20 -w 64 -g 2
Thanks !
P.S. I 20 is the maximum intensity - after 20 the driver crashes. My 5870 is Gigabyte card, locked and i can`t play with core freq and voltages.
P.P.S Tried with -w 128 - the same result... tried also :
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
del *.bin
sgminer.exe --no-submit-stale -k lbry -o stratum+tcp://lbry.pool.mn:8878 -u user.1 -p xxx -I 20 -w 64 -g 2
pause
the result was the same
