What phm-sgminer settings are you guys finding to be most relevant for the darkcoin kernel? Here with a 7850 the only setting changing my hashrate noticeable is the intensity -I. Other than that using something other than -g 2 seem to very slightly impact negatively the hashrate, but thread-concurrency for instance is making no changes at all...
For the record, i'm getting 910kh/s for -k darkcoin with the 7850 (standard bios and clocks), which seem fine in comparison to the reported rates in the DRK thread, but I would like to know if anyone find a setting to be of relevance.
clock settings are a major factor
I ask what your settings are?
ASUS 7850 1G
Win7 X64, 4G memory, AMD_Catalyst_13.1
Settings:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
sgminer.exe -k darkcoin -o stratum+tcp://stratum1.suchpool.pw:3335 -u lengx7.user2 -p x --gpu-fan 70 --gpu-engine 1000 --gpu-memclock 1100 --worksize 256 --lookup-gap 2 --thread-concurrency 6016 -g 2 --intensity 13
sgminer.exe -k darkcoin -o stratum+tcp://stratum1.suchpool.pw:3335 -u lengx7.user2 -p x --gpu-fan 70 --gpu-engine 1000 --gpu-memclock 1100 --intensity 11
sgminer.exe -k darkcoin -o stratum+tcp://stratum1.suchpool.pw:3335 -u lengx7.user2 -p x --gpu-fan 70 --gpu-engine 1000 --gpu-memclock 1100 --intensity 11 --thread-concurrency 8192
The results are all wrong HW
o.O
see above on this page.....
https://bitcointalk.org/index.php?topic=475795.msg5736704#msg5736704also 2 6850 and 2 7750
sgminer.exe --gpu-engine 900,900,950,950 --gpu-memclock 1000,1000,1400,1400 -I 16,16,14,14 -g 2 -w 256 --thread-concurrency 3200 --lookup-gap 2 -c dark.conf (<--only pools in here anything else crashes the computer for some reason)
gets about 800kh/s and 350kh/s
my 6850 1G,default tc=6016
sgminer -k darkcoin -o stratum+tcp://stratum1.suchpool.pw:3335 -I 11 --thread-concurrency 6144
