I mean on GPU your clocks?

And how to put "setx GPU_MAX_ALLOC_PERCENT 100" & "setx GPU_USE_SYNC_OBJECTS 1" in config for cgwatcher?
I have warning that i don't have them.
I tried:
"GPU_MAX_ALLOC_PERCENT" : "100"
"GPU_USE_SYNC_OBJECTS" : "1"
But it doesn't start...

sorry.....

both rigs:
core clock-1090
memory clock-1500
auto fan
no under voltage
and I don't use cgwatcher,so I can't help you with that.......
I got my R9 280x to ~771 Kh/s with 1090 core 1500 mem using sgminer 4.1 kernel zuikkis with undervolt to 1.100 and i use CGWatcher

nice,thank you for sharing......I must finally try that cgwatcher,seams no mining without him.....

can you please tell me witch 280x you have,because my asus is stock voltage 1075.....
Im using PowerColor R9 280x 3GB TurboDuo BF4 edition.
Actually i'm not really sure what the stock voltage is, but everytime the card crashes, the voltage set to it is 1.163, so i assume thats the stock voltage. lol.
