So is it possible to overclock a 5850 in linux more than 775Mhz without modifying the BIOS?

EDIT:
btw why can it be done in windows and not in linux?

There are several different types of Bitcoin clients. The most secure are full nodes like Bitcoin Core, but full nodes are more resource-heavy, and they must do a lengthy initial syncing process. As a result, lightweight clients with somewhat less security are commonly used.

Hi!
I have the same problem.
I have got a XFX 5850 black edition:

Code:
user@linuxcoin:/media/usb$ aticonfig --adapter=all --odgc
Adapter 0 - ATI Radeon HD 5800 Series
                            Core (MHz)    Memory (MHz)
           Current Clocks :    157           300
             Current Peak :    765           1125
  Configurable Peak Range : [550-775]     [900-1125]
                 GPU load :    0%

Adapter 1 - ATI Radeon HD 5800 Series
                            Core (MHz)    Memory (MHz)
           Current Clocks :    157           300
             Current Peak :    765           1125
  Configurable Peak Range : [550-775]     [900-1125]
                 GPU load :    0%
user@linuxcoin:/media/usb$

I am able to overclock from 765 to 775, or anything within the "Configurable Peak Range".
Whith AMDOverdrive I can change the range to set memory to 300, but I can't configure an higher value than 775 on core.

I have tried to cange the pcie mhz in the bios from 100 to 110, but the card still runs with 775 mhz...

Depending on which card it is exactly you should be able to set the clock to 875 on a stock card. I had to load a modified BIOS with 1.088 voltage to be able to run 900-975 stably.

Installing the ATI 11.6 Linux drivers (remove fgrlx packages first before installing) will let you set out of bound clock and memory settings with aticonfig.

export DISPLAY=:0
aticonfig --odsc 875,300 --adapter=all
