XFX r9 270x low hash problem

[BigNiggaTigga]

I just got a good deal on 2 270x's but they seem to only run at 375 kh/s each.

form my research these cards should be at 400-450 easy but no matter the setting I cant get any higher then 375

I have tried 2 different pcs with the exact results and it is very frustrating.

This is my current and fastest config

Code:

cgminer --scrypt -o stratum+tcp://stratum.flappycoinpool.com:3353 -u butthole.aids -p xxx --thread-concurrency 14208 --lookup-gap 0 --gpu-engine 1120 --gpu-memclock 1500 --gpu-powertune 20 -w 256 -I 18 -g 1

Anyone have any ideas?

Much appreciated!

wow that worked!!

thanks so much man

1 card going 450+ other just over 400 cant figure out why it wont go same speed

Code:

cgminer --scrypt -o stratum+tcp://stratum.flappycoinpool.com:3353 -u ball.sack -p x --thread-concurrency 8193 --lookup-gap 0 --gpu-engine 1060 --gpu-memclock 1490 --gpu-powertune 20 -w 256 -I 18 -g 2 -X 4

that look right?

edit: ok restarted the machine now im getting 450 each card. Cannot thank you enough! you helped me so much. leave your btc, flappy or kdc address and I send something your way at the end of next week

Glad I could help. Play around with the core clocks and see if you can get more hashes. I suspect you can probably get 470-480 with 1100 core clock. Just watch your temps. Also. Remove the -I 18 flag. It is not needed when running xIntensity.
