Title: XFX r9 270x low hash problem Post by: BigNiggaTigga on March 06, 2014, 04:09:43 AM 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! Title: Re: XFX r9 270x low hash problem Post by: gsrcrxsi on March 06, 2014, 04:40:38 AM I have the same card and get 465+ with it. Download the Kalroth modified cgminer
-X 4 (xIntensity) -g 2 -TC 8193 -gpu clock 1060 -mem clock 1490 Title: Re: XFX r9 270x low hash problem Post by: BigNiggaTigga on March 06, 2014, 04:54:50 AM wow that worked!!

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 Title: Re: XFX r9 270x low hash problem Post by: gsrcrxsi on March 06, 2014, 11:49:29 AM 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.
