Thread Starter 
I believe the the 8800 gtx and the gts will be g80s and the XFX 8800gt is going ot be g92, I can't wait to try the G80 again because they have a real easy OCP mod, the only problem is their PCB won't fit on my waterblock so Im contained to my accelero and suicide runs but this g92 should be an easy fix so I'm going to be able to run SLI at 850+ core clock and 1200 mem clock when the previous best for SLI on hwbot are still in the 700s and 1100s I believe

okay almost finished researching the 260GTX and Im looking for the data sheet for Vmem which is the uP6161N, so if anybody has it or can find it, thanks! Ive narrowed down the Vgpu which is the ADP4100 which I have the data sheet for and pix, just need to edit pix with info.

Also I have another link for datasheets:http://www.datasheetdir.com/

@doc-I cant wait to see what you do with those cards, good luck. Im searching now for some cheap cards to torture

EDIT: Ive found the datasheet that I was looking for and I got another datasheet link for you:http://www.datasheet4u.com/

Hi again!
The clocks now are
STOCK:600/400
vMODDED:823/560
@1,54v/2.2v!The core gets more and more...The mem needs more voltsWill give it 2,35v.Nothing past that.
Scores are 06

STOCK:3335
OC: 4658!!!


THIS IS 40% INCREASE!!!

Nice work!!

Care to share the mod info on that 2400PRO for the project?


Oh, and you guys can start posting IC info anytime you feel froggy.

Yeah i will share!I will post fotos as soon as i take some closeups!

2 ICs here!
This is the MOD for the uP6201BQ.
http://www.techpowerup.com/articles/...voltmods/151/2
Its widely used among the mid-high end ATI VGAs

Here is the vMOD for the ST L6788A
Used in the 5770 and 4770 models.It has I2C support too so it supports software adjustment!

This is the same vMEM controller on the GTS250 I was/am still modding [soon as I get a working DMM again :swearing:] I did some prelimb measuring on the IC..looks as if leg 5 is still mod point..and leg 7 ground. Can you confirm with your DMM? You would be doing me a huge favor to post the resistance as well I am 'blind' without my meter

@ pizza- Here are some more for you:

5770- GPUv




vmeasure points for 5870:


OCP mod for 5870: 18k fixed resistor = max 50A/ phase



Diamond 4850- non reference GPUv:



EVGA Dual-slot 9600GSO non reference: GPUv

vmem:




P5B-DLX- vDIMM:


vcore and vdroop:


MCHv:


OVP mod for vcore @ +2v:


ICHv mod for 500+ FSB:

chart for values of above mod:





...ok enough for now
post #239 of 1336
Sure will CL3P20 just give a moment and I will measure it for ya.

@CL-here is the data sheet for the up6161 and it looks to me as if pin#4 is FB and #7 is ground. Pin #5 is LDRV which provides the gate voltage for the linear regulator
pass transistor. But here is the data sheet and tell me what you think. Going to shut her down and measure the resistance. Is this your chip?

Also nice info and pix CL

CL, need VR values for the EVGA Dual-slot 9600GSO.

I'll get yours and theo's data updated either tonight or tomorrow. Leaving for work now and I've got a RockBand party tonight with a bunch of 30+ year old kids.
