r9 290x only 500khash?

[CoinPN]

turning on my cgi miner for 1 minute and the card get's heated up to 80C instantly. And it's only running on 550khash?

sapphire version, no overclock, 450w psu and good running fans.

-gpu-platform 0 -d 0 -w 256 -v 1 -I 13 -g 2 -l 1 -T  --thread-concurrency 11264

your thread-currency is a way too low for your 290x.

here is a list of cgminer examples for r9 290 & r9 290x

My card keep crashing with high thread concurrency. Btw will my motherboard melt if I go above 90C?

Remember to use these commands before you run CGMiner:

export DISPLAY=:0
export GPU_MAX_ALLOC_PERCENT=100
export GPU_USE_SYNC_OBJECTS=1

Then ramp your TC up as high as it will go. You will crash your driver/computer a few times, but once you dial it in, it's fine.

Those are the low usage settings from guiminer-scrypt.  You can use high usage, but >90C is dangerously hot.  You need to turn down your card voltages and adjust your card clocks.

guiminer-scrypt also includes the latest cgminer version, so you should get the same speeds in it you do with cgminer itself.

AMD support has stated that 95C is no issue for the R9 290/290X so I wouldn't be too worried about the heat. My 290 ran at 96C when mining at 820kH/s and had no problems except a damn loud fan.  
Now it's watercooled and running at 65C on full load. And use 1 GPU thread in the settings, not 2. But with intensity 13 that kH/s is normal.
