In the first pic we have the voltmod its very easy to do any of the 4 points marked in red can be used its just a 500 ohm trimmer to ground set to max resistance. Note for Brad this card is blue I think its a 8800GS it only has 2 phases as do the cards we are doing noted by the three missing components to the right of the mod the three components above the missing ones are for the second phase. But its exactly the same.   Next pic is of the OCP mod you have to solder 1.2k ohm resistors on top of the capacitors to lower its sensitivity. You can use values up to 4k ohm as long as they are all the same values. This pic is of a 8800GTS and has the three phases hence there are three resistors that have to be soldered on and the missing components in the first pic are there. Brad you only have to do the 2 caps that are in the positions on your card if you do this mod. I haven't done this mod as yet its coming.  Here is a pic of how I actually done my card.  |

Vmem mod is a 20K ohm VR to pin 4 and Ground of the P3459 as in the picture below I just used the end of the ceramic Capacitor for ground. I have also put red arrows pointing to the caps that you solder the resistors onto the top of for the OCP mod. I got my resistors off of a old 478 board they are 2.7K numbered 272. When finding the resistors the numbers on them go like this. The first 2 numbers are the values and the third number is the amount of Zeros 272 = 2700 ohms or 2.7K ohms. You can use any value from 1.2K ohm up to 4K ohm. closer to 1.2 will give greater headroom though.  I also like to add a tail to my cards so I can just leave the meter connected its just a female connector out of a molex plug with a bit of heatshrink on it. Saves having to hold a probe on the card while adjusting.  |

Thanks, will have my soldering stuff out this weekend. Been awhile will have to check what's in the box for VRs.
There is a FX4600 mod up on the Bot.

added the OCP finally to my 8800GTS those look like 2.2k ohm resistors, post above noted 1.2k ohm (Brown, Red, Red) Vin |

I read it, but somehow missed that.

got a 9800GTX+ gonna be modding soon this thing is pretty damn good hit 1400mhz with the mem no mods not even gonna mod that since most dont get over 1300mhz  |
