Problem OC Sapphire 5830

[xof7]

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.

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

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
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

[jh1523]

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

[xof7]

I was able to overclock the core with overdrive but underclocking would lock the machine up.

I'll give atitweak a try. Thanks guys.

[plastic.elastic]

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

[plastic.elastic]

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...

  self.commandQueue, self.output_buf, self.output)
[29/07/2011 07:54:57] Result: 167a2583 accepted         

Does anyone know what it means?

[jh1523]

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.
