Hi guys,
I posted this in alt coin section but unfortuantely no response and its been a few hours.. I'm hoping someone here can chime in.. a fix would be MASSIVELY appreciated
I have probably tried about 100 different command lines ...
i have somehow once managed to get my cards at a solid 710khash each and now for some reason i cannot get it over 650
can anyone with some experience of these cards give me some insight.. i have no idea what i did that time to achieve the stable 710 per card so I'm open to ideas.
I Can tell u what I have tried so far... you will be shocked :~
I'm currently using this on my 4 card rig..
' cgminer.exe --scrypt -I 20 -g 1 --thread-concurrency 24000 --gpu-engine 1020,1020,1020,1020 -w 256 --lookup-gap 0 --gpu-fan 90'
and getting a stable 640-650khash but its not good enough and i know these cards can do more
and on my 3 card rig
-I 13 -g 2 -w 256 --thread-concurrency 8192 --gpu-powertune 20
only achieving 550khash... i've messed around with the clock in 5mhz incriments up and down like you would not believe... no joy
im basically losing between 70-200k hash per card at the moment across those 7 active cards..
much appreciated to anyone who can help
