Gigabyte Tutorial: Vmodding GTX2xx Lighting

rev1.0
Basic GPUv:

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!

Please update for the Lightning GTX260/275

Nice mod CL3P20, I like the VR on the OCP, I used that on my 8800GT and can definitely verify that it works. You have some serious skills my man, very impressive with the gun, solder slinger indeed

thats not mine! I linked the source in my post..[XS] a user there got some info direct from Gigabyte, for their recent GTX260/275 Lightning contest.

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

Samsung .8ns ...great for speed and can handle voltage over 2.15v..unlike some other IC's.
post #78 of 1500
that PCB looks almost identicle to the 8800GTX, I wonder if a full cover block could be interchangeable and if the mounting holes are in line

I'll get this updated soon.

CL, there is normally a spreadsheet with a VID layout like that. Did he post one?
