Hello,
I want to make v-mod on the reference HD4850 simplest way possible. I do not trust my soldering skills and I do not like pencil mods, because they change their properties after some time. However, I ran an idea:
What do you think about this:
1. I change BIOS voltage values using RBE 4 units down (instead of 1.158V will be 1.006V, etc.)
2. I would flash the card with the modified bios.
3. I would paint a resistor with conductive paint using method similar to pencil mod (method for below 1.4V)
4. I would OC and change the voltage in bios.
What I should get:
Since the pencil mod on the resistor provides a maximum of 1.4V under stress, I will reduce this value in the BIOS to 1.24V. I could peacefully (without the use of potentiometer) flash card to voltage that I like (maximum of 4 units higher, so 1.28V, 1.32V, 1.36V and 1.4V). Resistance will not change after a month, because mod will be executed by paint instead of graphite pencil.
What am I afraid:
- That the short-circuit resistor hurt anything.
- That a maximum of 1.4V at the method of the resistor is fake, and indeed it is a much higher voltage
- That despite the settings in the BIOS, the card will receive the maximum voltage (> 1.4V)
- That no one never tested it and it is madness.
Can anyone allay my fears before I burn my HD4850
