Hi dejjin
If I interpret your post correctly, I already did what you suggested:
I tried this:
1) uninstalled driver
2) changed voltage in 6850 bios
3) reboot - no BSOD
4) installed driver - reboot - BSOD
According to powercolors tech support, AMD drivers check if the clock...
I found a way to change both clocks and vCore: "Ati Tray Tools".
After uninstalling CCC (and deactivating AMD polling), I was able to set the low power state 150MHz/300MHz/0.95V as well as the standard-clocks at reduced vCore: 775/1000/0.95V.
It is stable and considerably reduces the heat...
Update:
Changing bios settings without a driver being installed does not seem to change the clock/voltage settings. Here is what I did:
1) Uninstalled drivers (system settings - express uninstall)
2) Changed bios settings: clock info 01 (100MHz/150MHz/0.95V) to (200MHz/300MHz/1.1V). This...

From reading the RBE tutorial it did not become absolutely clear to me how this bluescreen comes about. Does the driver compare the bios settings to the values...
Update:
Changing any of the clock settings via RBE results in BSOD when booting windows (i guess that is to be expected due to AMD drivers).
Changing voltage settings via RBE results in BSOD.
I can change the fan settings via RBE without triggering BSOD => modifying the bios and flashing...
Dear Experts!
For the passively cooled 6850 SCS3 it would be most desirable to undervolt. But when I change any voltage via RBE1.28, I get BSOD after reboot.
So far I found no tool to undervolt this card, but TRIXX can overvolt it so it might by possible.
Is this problem caused by this...
