Anyone got a good config file for my computer?   Roll Eyes
I found that under clocking the core increased my khs. My stock core clock is 1040 on my Gigabyte R9 290, but saw improvement by lowering it until it reached 967, then it started dropping.

Try MSI Afterburner for this. start your miner and Afterburner. Then make tiny changes in Afterburner and watch the result in real-time in your miner. Keep going until you find the best core clock.

On TC, I suggest you use a multiple of your # shaders, +-1. Not sure why the +-1 helps, but it does.

Here's my config if it helps, it does 845khs.

"intensity" : "20",
"vectors" : "1",
"worksize" : "256",
"lookup-gap" : "2",
"thread-concurrency" : "30719", 

"gpu-engine" : "967",
"gpu-memclock" : "1250",
"gpu-powertune" : "20",

"temp-cutoff" : "90",
"temp-overheat" : "85",
"temp-target" : "80",
“auto-fan” : true,

"api-port" : "4028",
"expiry" : "120",
"failover-only" : true,
"gpu-threads" : "1",

"log" : "5",
"queue" : "1",
"scan-time" : "60",
"temp-hysteresis" : "3",

"kernel-path" : "/usr/local/bin"

Add to beginning of your batch file:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

Better if you start your own thread next time so people can easily see what you did and what was offered for you to do.
