hi, i've got a miner finally working on linux (ubuntu 10.04 64-bit) on my HD 4850.  i'm using this command:

Code:
python ./phoenix.py -u http://user:pass@pit.deepbit.net:8332/ -k poclbm VECTORS FASTLOOP=false AGGRESSION=9 DEVICE=1

but i see on https://en.bitcoin.it/wiki/Mining_Hardware_Comparison some have gotten it to be 101 Mh/s  but i can't figure out how to get my clock/mem speed like they say (817, 500).  aticontrol doesn't let me set those values, since they are both outside the "Configurable Peak Range":

Code:
$ aticonfig --odgc --adapter=all

Adapter 0 - ATI Radeon HD 4800 Series       
                            Core (MHz)    Memory (MHz)
           Current Clocks :    625           993
             Current Peak :    625           993
  Configurable Peak Range : [500-700]     [750-1200]
                 GPU load :    99%

hmm.  i thought there was a useful post here explaining exactly how to unlock it, but now its gone.....  i was just able to get the necessary hardware together to install windows and try unlocking.  please repost or PM the instructions.


edit: found it using google cache.  supermine, not sure why you removed the useful information:

1) boot into windows (i kno it sux0rs).
2) install gpu-z
3) pull bios
4) install atiwinflash
5) start->cmd-> ATIWinflash -unlockrom 0
6) install RBE from techpowerup
7) start RBE and load bios you pulled earlier with gpu-z
8) in RBE change clocks, etc..
9) go to acquire flash and browse for path of ATIWinflash
10) flash the device
11) reboot into linux and be happy about the changed range in aticonfig tool
12) send 0.1 BTC thank you fee to 15DNbzruPy6b6MDutAqRE6BnruhpktGbiH

Well, i've gotten to the part where i am in RBE and ready to change the clock settings, but i'm confused by all the places.  what am i supposed to change in order to increase the range that i can see with aticonfig?  here's a screen shot:

i tried changing the "Clock info 03" to 800 & 500, and that didn't work, the card wouldn't work, so i had to reflash my backup.  any suggestions?

after installing the catalyst 11.6 drivers (instead of using fglrx), i was able to adjust the cpu and mem speeds outside of the range.  however, none of the reported settings on that bitcoin.it article worked, they all caused the card to freeze.  the best i've been able to get so far is by just increasing the clock to 700, yielding an extra 7 Mh/s or so.... screw this

I wasn't able to drop my 4850 any lower than 620MHz memory, and currently I'm running with a core of 735, and netting about 82MH/s... but that's using RivaTuner in Windows.  I'm going to mess with the MSI Afterburner build later tonight... but I need more cooling I think.

thanks, this setting works for me, but only nets about 71 Mh/s here, however no increase in power consumption (still only using ~70W).  i'm using an ASUS EAH4850 @ stock voltage (1.123V i think)

but I need more cooling I think.
that's for sure... even at just 71 Mh/s and manually setting the fan to 100% the temp is still 87.

i thought it would be nice to max out the existing hardware i have w/o investing in a higher-end card, but it's looking like there isn't much interest in this card anymore.  maybe i get 0.07 BTC/day from its mining...
