1 x Saphire Toxic 280x with CGMiner running @ 410K
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer.exe --scrypt -o stratum+tcp://s.eu.vertcoin.org:3333 -u xxxx -p xxxxx -g 2 -w 256 -I 13 --thread-concurrency=8250 --gpu-engine=1160 --gpu-memclock=1860 --auto-fan --gpu-powertune 20
Ok I managed somehow to achieve decent speed 180KH on my 270
-I 12 -w 256 -g 2 -v 1 --thread-concurrency 4648 --lookup-gap 2 --gpu-engine 1050 --gpu-memclock 1500
I had to change thread concurrency to around 4000 , thanks for help
Is there any way to make it work faster?
Your on the 270 so - up your thread-concurrency to 8192 (-/+20). Save a copy of your .bat file and play with the numbers, gradually upping them until you get the best out of your card. Down -12 to 11 (until you get higher speeds then change +1 each try)
Good Luck x
