Title: XFX r9 280X and hashrates Post by: sevoque on January 23, 2014, 11:37:24 PM Hi guys,
I posted this in alt coin section but unfortuantely no response and its been a few hours.. I'm hoping someone here can chime in.. a fix would be MASSIVELY appreciated I have probably tried about 100 different command lines ... i have somehow once managed to get my cards at a solid 710khash each and now for some reason i cannot get it over 650 can anyone with some experience of these cards give me some insight.. i have no idea what i did that time to achieve the stable 710 per card so I'm open to ideas. I Can tell u what I have tried so far... you will be shocked :~ I'm currently using this on my 4 card rig.. ' cgminer.exe --scrypt -I 20 -g 1 --thread-concurrency 24000 --gpu-engine 1020,1020,1020,1020 -w 256 --lookup-gap 0 --gpu-fan 90' and getting a stable 640-650khash but its not good enough and i know these cards can do more and on my 3 card rig -I 13 -g 2 -w 256 --thread-concurrency 8192 --gpu-powertune 20 only achieving 550khash... i've messed around with the clock in 5mhz incriments up and down like you would not believe... no joy im basically losing between 70-200k hash per card at the moment across those 7 active cards.. much appreciated to anyone who can help Sev Title: Re: XFX r9 280X and hashrates Post by: -ck on January 23, 2014, 11:39:01 PM Doesn't change the fact you're in the wrong forum section.
