With my R9 290 i cannot seem to get any higher rate than around 7000 to 8000 Khash. Seems kind of low to me Huh

.
Somebody got a clue on how to get a better rate? I tried to play around with the -s parameter, but doesnt realy affect the hashrate.

To be complete:

Intel i5 4670K, 16GB memory, Win 8.1 X64

Any help will be appreciated !! Thanks.

That looks fairly decent. Do you happen to know your card's clock speeds?
Check GPUz while the miner is running: http://www.techpowerup.com/gpuz/
I found out the hard way that cgminer never reset my clock speeds so the memory was badly un-derclocked. It ended up cutting my hash speed in half.

I have same problem with AMD 7790 (2700khs) GPU-Z shows that gpu clock is 1100 but memory stays at 150 instead of 1500, gpu load 0%. Same when I mine Bitcoin and Maxcoin but with max performorance (they dont use memory alot). Looks like memory is not triggered to be used. Not optimized xptMiner works the same.
