Title: Sapphire 11221-00-20G 280x can't break 700 kh/s Post by: vargoneti on January 27, 2014, 04:50:27 PM hello ,
i bought one of these 2 weeks ago , after playing with various settings and clock speeds the best i could get ist around 690 kh/s. Could anyone tip me how to go above ? settings i use currently : --shaders 2048 -g 2 -I 13 -w 256 --auto-fan --gpu-fan 30-75 --temp-cutoff 90 --temp-overheat 85 --temp-target 72 --gpu-powertune 10 gpu clock 1040 , mem clock 1500 , vddc 1225 (if i try to go lower than 1200 it crashes ). gpu powertune 10 or 20 did not improve anything. Any help is much appreciated ! Title: Re: Sapphire 11221-00-20G 280x can't break 700 kh/s Post by: Silvano on January 27, 2014, 05:38:40 PM try to add: -g 1 --auto-fan --thread-concurrency 22528
delete: -g 2 --gpu-fan 30-75 if you want to undervolt, download TriXX from AMD site, and try it, card wouldn't be voltage loked :) Title: Re: Sapphire 11221-00-20G 280x can't break 700 kh/s Post by: mezza550 on January 31, 2014, 05:01:02 AM hello , i bought one of these 2 weeks ago , after playing with various settings and clock speeds the best i could get ist around 690 kh/s Hey Vargoneti, and luck with this, were you ever able to go above 700?
