ATI 3850/3870 Voltmod thread

Here it is



I had 0.1v increment by reducing it to 1.3 KOhm, so you can count if you want

Ps: obviously there's a K missing between 2.26 and Ohm

I've A GeCube 3850 512MB Turbo 3 Card with an AC S1 and dual 92mm fans

the ressistor is 2.44 kohm on my card default and i measured a vcore of 1.26V

this is a pic of my card



green marked are my measured vcore points
blue is the ressistor i penciled

if i penciled it down to arround 2.00 kohm or 1.8 kohm my measured vcore is lower than default

(around 2kohm it was 1.18volt)

do i measure the vcore on wrong points?

it seams that this is the wrong resistor but my layout is a little bit different what resistor i've to use?

what to do with this card help...

i get 780Mhz gpu clock my card need more vcore
