Title: Problem OC Sapphire 5830 Post by: xof7 on July 28, 2011, 06:22:33 PM I'm running an ubuntu 10.04 server with xfce.
The server has an athlon 140, 2gb ram, and 2x5830's. I have them both overclocked to about 950mhz core. I tried to underclock the memory but everytime i do so it locks the machine up. I have this same exact hardware also running under windows xp sp3 and I get the same results. ANY modification to the memory clock speed on either GPU and it locks the machine up... Any ideas? Thanks. Title: Re: Problem OC Sapphire 5830 Post by: bitminersunion on July 28, 2011, 06:56:33 PM i have never figured a way to underclock mem in linux.
and I know its not available in any non commerically available util better go to windows 7 and use msi afterburner Title: Re: Problem OC Sapphire 5830 Post by: jh1523 on July 28, 2011, 07:02:09 PM It's very easy to over/underclock both core and memory in Linux. Use atitweak. Example:
atitweak -A 0 -f 100 -e 900 -m 300 will set for adapter #0: fan to 100%, core to 900 and memory to 300. Code: atitweak -h Title: Re: Problem OC Sapphire 5830 Post by: Bloodred on July 28, 2011, 07:06:58 PM Have you tried older/newer driver versions, especially on Windows? Also make sure you don't have some weird BIOS preventing OC.

Title: Re: Problem OC Sapphire 5830 Post by: plastic.elastic on July 28, 2011, 07:23:25 PM Does the AMDOverdriveCtrl in linux let you overclock your card? If so how? I tried it from the GUI and it can only let me set clock the the maximum of my default clock ... strange. However i have read in other threads that ppl have been using it to overclock their cards. Any clues?
FYI, its 5850 black edition with default clock at 775/1125 Title: Re: Problem OC Sapphire 5830 Post by: jh1523 on July 28, 2011, 07:25:25 PM Read the thread I linked to, it doesn't and that's why the author of atitweak decided to write his own.
Title: Re: Problem OC Sapphire 5830 Post by: xof7 on July 28, 2011, 07:27:38 PM I was able to overclock the core with overdrive but underclocking would lock the machine up.
I'll give atitweak a try. Thanks guys. Title: Re: Problem OC Sapphire 5830 Post by: plastic.elastic on July 29, 2011, 07:16:44 AM But according to this thread : http://forum.bitcoin.org/index.php?PHPSESSID=24170fa90fad3338d4b40a9c5143c1d1&topic=29021.0
Which i have been following, the AMDOverdriveCtrl should let me overclock my card. I read the atitweak thread, and it seems ppl complaining about over-volting, How do i find which driver version i'm using? I'm running linuxcoin 0.2b-final Title: Re: Problem OC Sapphire 5830 Post by: plastic.elastic on July 29, 2011, 07:58:39 AM I decided to try atitweak, and boy it was much simpler, cleaner as well
So i finally can overclock my card. However, i just try phoenix miner with phatk kernel on linuxcoin for the first time and i got this msg/warning right after executing the command Code: [29/07/2011 07:54:50] Phoenix r111 starting... Does anyone know what it means? Title: Re: Problem OC Sapphire 5830 Post by: jh1523 on July 29, 2011, 10:19:58 AM Sorry can't help you there. It appears there's something wrong with the version of phatk you use (did you install diapolo's version without updating __init__.py as well?)
That's probably a question to ask in the Linuxcoin thread. Alternatively you could give BAMT a try, been using it with great success for a week now. http://forum.bitcoin.org/index.php?topic=28967.0 Title: Re: Problem OC Sapphire 5830 Post by: plastic.elastic on July 31, 2011, 11:39:17 PM Thanks for your help
I still cant post in regular section :( ... newbie restriction Also i'm having problem booting Linuxcoin with 4 x 5850. As mentioned above, i successfully ran Linuxcoin with a single 5850 (mining and everything seems to work fine) But i cant boot into Desktop with 4 x 5850. It hang after the splash screen, seems like X-server got stuck during the initiation. I can boot fine with 4 x 5850 to Windows 7, so i know its not the hardware. I really want to post in Linuxcoin thread, when can i pass the newbie restriction? Title: Re: Problem OC Sapphire 5830 Post by: dime on August 01, 2011, 06:05:09 AM I installed amd drivers from ppa:ubuntu-x-swat/x-updates and aticonfig never lets me go outside the configurable range, but afterwards, I manually install amd drivers from their site and the new aticonfig command lets me set it to whatever I want.
