Is this coming from gigabyte?How are u suposed to perform this mod and not destroy your card...Every step is more dangerous than the previous!

yeah..its from Gigabyte..and I would say..5/5 for difficulty..I'd be sweating a little for sure..but its all perfectly do-able. I would not want to sit down and go through the whole process in 1x session, either .

*gonna pickup 4x 16v 1000uf caps for input phases on Bastiaan's GTX275 this week Adding 7x 6.3v 1800uf caps to output phases [6x-GPU and 1x vMEM]. From what I have read on the datasheet..the input phases will be the critical component in the G200's ..they dont have much capacitance and are limited to a set amount of total amperage, without further mods. Hopefully keeping voltage trim tight, on both 'sides' will boost stable clocks...seems to be the trend with every factory OC'd version featuring more power phases for GPUv..and getting moar speed.

Doc and CL, I'll get you guys updated here soon. One question, do your VID patterns have a spreadsheet? There should be something like this to go along with the marked layout.

OK, here are today's updates. If anything looks wrong plz say so. thx again for your contributions.

GeForce GTX 260 non-reference PCB (Gigabyte v1.0): GPU GPU info (Click to show)
Pls exchange A (R1025) and B (R1022). A->B; B->A

And you can use the adjustable resistance on C (C157). I tryed resistors from 100 Ohms - 470k Ohms, best results i have with 10 kOhms trimmer. Card works perfectly with 1,52V on GPU and was fully stable in 3DMark Vantage ... at 1098 MHz ... no OVP/OCP triggering ... tested on GTX 260 and GTX 275, working really great!

Here are some support pics for the reference series GTX275..like the one I am modding for Bastiaan .


Input phases = yellow
Output phases = red
Mod points = purple


OP needs a MEM mod for the 275.

Updated the 285 info.
What size VR for the 7200GS?
GPU link broken for the 8400GS.
Oh, and need the VID table for the 9600GT VID mod. lol, you actually found a 96GT I haven't figured out yet.

Otherwise, I think I got everybody updated.

@ Pizza- the 96GT VID mod for the RT88 is in the datasheet..bout halfway down..I'd paste it, but Im driving

..I'll get the vmem for 275 later too!
