Current settings: (with latest Vertminer)
setx GPUUSESYNCOBJECTS 1
Vertminer.exe --scrypt-vert -o stratum+tcp://eu.hashing.at:3021 -u Sapphire.Sapphire -p x -s 10 -E 30 -Q 1 -w 256 -I 12 -g 2 --lookup-gap 2 --gpu-powertune 20 --gpu-memclock 1500 --gpu-engine 1070 --thread-concurrency 6912
I've tried a tc of 8192 before, and it's about 10 KH lower on average.
I also have dual-bios so perhaps I should try to flash my card to a Sapphire/Gigabyte 7970 GHZ?
Any advice would be appreciated.
