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.

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. atitweak -h Usage: atitweak [options]
Options: -h, --help show this help message and exit -l, --list-adapters Lists all detected and supported display adapters. -s, --status Shows current clock speeds, core voltage, utilization and performance level. -e ENGINE_CLOCK, --set-engine-clock=ENGINE_CLOCK Sets engine clock speed (in MHz) for the selected performance levels on the selected adapters. -m MEMORY_CLOCK, --set-memory-clock=MEMORY_CLOCK Sets memory clock speed (in MHz) for the selected peformance levels on the selected adapters. -v CORE_VOLTAGE, --set-core-voltage=CORE_VOLTAGE Sets core voltage level (in VDC) for the selected performance levels on the selected adapters. -f FAN_SPEED, --set-fan-speed=FAN_SPEED Sets the fan speed (in percent) for the selected adapters. -d, --set-fan-speed-default Resets the fan speed to its default setting. -A ADAPTERLIST, --adapter=ADAPTERLIST Selects which adapters returned by --list-adapters should be affected by other atitweak options. ADAPTERLIST contains either a comma-seperated sequence of the index numbers of the adapters to be affected or else contains the keyword "all" to select all the adapters. If --adapter is missing, all adapters will be affected. -P PERFORMANCELEVELLIST, --performance-level=PERFORMANCELEVELLIST Selects which performance levels returned by --list- adapters should be affected by other atitweak options. PERFORMANCELEVELLIST contains either a comma-separated sequence of the index numbers of the performance levels to be affected or else contains the keyword "all" to select all performance levels. If --performance-level is missing, all performance levels will be affected.

Have you tried older/newer driver versions, especially on Windows? Also make sure you don't have some weird BIOS preventing OC.

where do i get atitweak? thanks

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

Read the thread I linked to, it doesn't and that's why the author of atitweak decided to write his own.

I was able to overclock the core with overdrive but underclocking would lock the machine up.
I'll give atitweak a try. Thanks guys.

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 [29/07/2011 07:54:50] Phoenix r111 starting... [29/07/2011 07:54:50] Connected to server [0 Khash/sec] [0 Accepted] [0 Rejected] [RPC]kernels/phatk/__init__.py:415: DeprecationWarning: 'enqueue_read_buffer' has been deprecated in version 2011.1.

Does anyone know what it means?

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

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?

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.
