Vmod 3850 through BIOS apparently IS possible....

This is very interesting!

So the 3850 has a 2D value of 1.014V ..and the 3870 1.241V ?

They both run at 300MHz in 2D, so why can't we have the lower value on a 3870?

If I try edit the bios to my 3870 and the voltage for some reason is to low, would that mean that I can no longer boot up the card again...meaning bricking it?

My 3850 256Mb is running on 1.014V in 2D, and it's flashed to 770/1000 for default clocks. I think that 3870 must run at 1.014V in 2D. It's better GPU (XT version) and it must be capable to run at lower voltages + it's PCB is much better than PCB for HD3850.

Yes, this sounds logical.

I will try tomorrow, hopefully I get a much cooler card when idle
