    I'd recommend fixed 20ohm resistor and I really hope that you have water cooling at least. 20ohm ~ 1.5-1.6v. And be careful, that vddc solder point is really tiny.

    Yes, I think so. In the RBE it has high profiles at 3 and 9. 4 to 6 are UVD profiles. I've changed the 3 and 9, both to the same voltage I mentioned before. Now I have it at 1.363 (exactly 0.1v above normal) but no success again. Even people from XS forum didn't have any luck with BIOS voltage...

    Radeon HD 4870 Voltmods

    Hi. What do you mean with the "in 4 steps" ? I've modded the 4870 BIOS using RBE 1.11 but it doesn't seem to have any effect on voltages. I tried increasing it from 1.263 to 1.276 and 1.302 but without success. The vcore was not changed. So is there another way to up the GPU voltage by 0.1v? Thanks.
