So, the title already says everything by itself.
[/size]i have been trying to mine litecoins with my [/size]Sapphire Vapor X R9 280X with the BIOS 15.040, however, it barely reaches 565khs.[/size][/font]
[/size]If you want more information, I have Windows 8, 8GB of RAM, my CGMiner is 3.7.2 and my command lines are the following:[/color]
[/size] [/color]
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer --scrypt -o stratum+tcp://usa.wemineltc.com:3335 -u CardellB.1 -p 1234 --thread-concurrency 8192 --lookup-gap 2 -w 256 -I 13 -g 2 --shaders 2048 --temp-cutoff 90 --temp-overheat 85 --temp-target 70 --gpu-engine 1090 --gpu-memclock 1500 --expiry 1 --scan-time 1 --queue 0 --gpu-powertune 20
pause
 
I would like to know ways that I can achieve at least 700khs (I saw people with more than even 750 with the same VGA) but [/size]WITHOUT CHANGING THE BIOS, so if this is the only alternative, tell me and I will just do what I know some people did.
 
I thank everyone that helps me!
