hi predator.
is it possible to use a 10 ohm resistor instead of the 20 ohm? (vgpu-mod)
thank you.

credit goes to shamino at vr-zone he did the mods before anyone knew what a 2900xt was

nice guide tho 10ohm will not work unless oyu have ln2 on the card at -40c min before you post

20ohm is pushing it I use 50ohm myself

As Jason says, 10ohm is too much low you'll need extreme cooling once you hit 3D , i used 20 ohm VR and went out fine

thank you.
i decided to go for 2x10 ohms in series.

Why do that when you can controll it in software?

the software isn't working 100% and this is more accurate
