yeah I edited my post a few minutes ago...lol. I found the pdf for the chip but I'm no expert, I want to see what the real modders say to check, I'm sure a mod is possible but I wouldn't want to give you the wrong advice.

Whats the FB? Which part needs shading in?
Heres a quality picture taken while the card was still in the PC:
I've found this, its an x1950 but its the same Nexsem 2415 chip

In most places stealing is a crime. With Paypal it's a 'business model'.
the FB Pin is the Feedback it controls the Vcore on your card the pic is correct this is the Fb pin so now you have to find the resistor that is connected with the Fb pin on your 3850 for start and then i will tell you what to do![]()
just take a multimeter and see witch resistor measures 0Ωhms with the FB pin
post a good pic of your card it will help us a lot
ok try measuring those resistor and see witch one shows 0Ωhms with the FB
if you cant put you multimeter prob on the FB pin because the are tiny you can put it on the capacitor that is connected to the FB see the trace line in the image that leaves the FB pin and goes on the tiny brown smd capacitor

Have anybody got meassure and voltage point to Gigabyte HD3850 256MB ? (Red PCB)
hey, no problem, i completely understand.![]()
the thing about pencil mods is that if your card blows up, erase the mod and rma it! while some may call this irresponsible or unethical, i believe that since we paid for it we should be able to rma it. the big manufacturers have money to replace it, we don't.

thx!
I used 100k ohm set to 90k ohm and my card is burned...Do I have to use 500k ohm and what is resistance for let's say 1.5v?
HAHA i am very very happy guys..pencil mod done! now i am testing..later i put my result..THANK YOU Random Murderer you are the BEST!

You must have done the mod wrong mine 3870 can handle over 1.9v without burning and i am using 100kohms

Finaly I got it.
I voltmoded my PowerColor HD3850 512 PCS and applied a "little" bump to 1.38V VCore. I changed the bios to the HIS HD3850 ICE3 (ver 071).
I also changed the "two wire" Zerotherm by an original "3 wire" Zerothem 810.
Now I got my HD3850@864Mhz Core and 1080 MEM. (about 30% core OC). 45° idle and 65° full load.
With my P5B Deluxe, e6600@3.6Ghz I'm near the 12500 points in 3DMark06 (12247). I'm Happy....![]()
