Vmod 3850 through BIOS apparently IS possible....

[Bo_Fox]

This time, I made sure it's from your ORIGINAL GeCube bios, with everything set at 1.33v--even in low-power mode it will be running at full voltage, so your card will be warm all the time. Make sure to set the fan speed to 60% or higher in Rivatuner.

Here's the BIOS with 3870 voltage all the way.


Description:
HIS GeCube 3850 X-Turbo III 512MB 725/900 default clocks
MODDED BIOS WITH 3870 LOAD voltage (2-D: 1.327v, 3-D: 1.327v)
