Vmod 3850 through BIOS apparently IS possible....

[eva2000]

And here is the modded bios from the same one in my last post, but with 3870 voltages. It is the same as the one that the-strokes edited for me, but I fixed the checksum so that it's exactly the same as default (no need to 'force' flash).

(Keep in mind that it does not allow for overclocking within CCC but can be overclocked just fine using Rivatuner). This one gave me a 50Mhz stable core boost over the default one.

Description:
HIS Radeon HD 3850 IceQ3 TurboX 512MB 736/982 default clocks
MODDED BIOS WITH 3870 voltage (2-D: 1.241v, 3-D: 1.327v)
