yes i know but we`ll just get the adresses when we readout the bus protocol

Now do you imagine readout of protocol with two devices on same address?
There is magic resistor for address selection on PWM

i can`t find magic resistor
just found some 0 ohm jumpers and some resistors but i`m not sure witch resistor is for adressing
does adressing works from 12Vinput to magic resistor and current flow over magic resistor to adresspin = adress?

from 3.3V
Try pin 20 300ohm is for stock addr, 1.02k for +1bit, and so on

i think thats the smb going into the gpu, not linked with the rest of the devices on vga if not like tin said mobo + vga conflict may arise. better to solder to the controller smb

no there isn`t a smb connection to mabo they don`t added jumpers
you can see it here on first pic http://kingpincooling.com/forum/show...6&postcount=33
now i`ve connectet the wires right to the controller to keep wires short won`t get bad signals

i removed the resistor and added a VR to find right resistance
right now i`m sitting here and try doing my homework

need some help from the master
i`ve tried to get it working but no way
i`ve tried all possible resistance between 1,02k and 20,5k but no way
than i desoldert the adressing resistor from the 2nd 1165 controller (12,1k) on pcb and set resistance to 340ohm
retry 1,02k to 20,5K no way evbot would`nt work
but some strange things would happen with 6,49k and 12,1k @ R_sel0
3sec after startup VCC rais up to 1,66V
VGA is getting realy hot with stock cooler but still alife
