Hi Ket,
I have flashed my P5Q with your last 2209.rom and the mobo work great.
Thank you for your work man.:up:

Hi guys!
That is right , I didn't get it to work using 100k vr connected to FB pin,but using a 50k vr is working fine:up:.I recommend you to get last bios update from gigabyte.com for better...

any idea ceemic?

yes i turned it to the end in clockwise.

When i touched the wire coming from FB to VR actually have 99k between FB and GND and must nothing happened(only when start turns VR) , but the card is shut down like a protection thing

Another Pic

first pin (our look) is unused ,midle pin is conected to GND and last pin i used to go to FB
yes i checked with DMM and have 00.4 ohm on scale 200ohm between FB pin and that resistance
I dont...

The first pic is from Duncanoc , i just put my card in case
94555
and this is vr but no wire , i just remouve it
94556
i hope is clear , if not tell me and do more pics

ceeemic , is not working;i solder to the first resistor from FB a VR 100K to GND.
card not even start and i set the VR to 100k before connect.

CEEMIC, the circuit between FB and COMP is closed with no connection to GND
Whatever the default resistance between FB and GND is 7.24Kohm mean i must use 145Kohm VR.
Here the circuit.
94495

Thank you Ceemic.Only one more thing is necessary:measure point vgpu.
If i get that i will start do work and came with results.

I like hardmode. If you know were must solder a trimmer res. I be glad!

If I give you a detalied schematics of controller(npc5392) pin 17 can you tell me what resistor or ceramic cap must pencil?

Hello DuncanOc!
I have the same video card Gigabyte hd4850/zalman
Please tell me if you identify what rezistor must pencil and were is the point
for measure final GPU voltage.:shrug:
We can't...
