NVIDIA GeForce To Quadro Soft-Mod Guide

According to the guide, the card used is Geforce 8800 (G80) and under the nvdisp.inf file, there are 2 Quadro cards that uses the same G80 core, which is Quadro FX5600 and Quadro FX4600, how do I know which Quadro to chose if both are using the same core? The guide did not explain it well in choosing a Quadro card.

Please help. Thank you

when you chose model always look on same hardware parts on it
example 5600 haves 1.5 Gb of ddr3
and 4600 haves 768 Mb of ddr3

Yes, you can make the drivers and OS recognize it as a Quadro card, but you won't get performance increase in professional 3D applications such as Maya. Try run some professional 3D benchmarks for comparison and you will see what I mean.

EDIT: I think it only gave a slight improvement in D3D based professional 3D applications like 3ds Max (and screws up the driver at the same time, causing it unable to run OpenGL applications properly). It is confirmed that it doesn't work with OpenGL based professional 3D applications.

well it works here
anyway quadro drivers are different than regular driver
it have more optimizations for 3Dmax and it also have additional driver to boost quadro performance in the 3dmax
just take a look on texture fillrate it have been boosted by 4GTexel/s
well regular 4600 works on gpu 700Mhz and 900ddr
and i dident clocked this one

Yeah it should be tested. From what I read, he should be getting up to 30% improvement in certain rendering scenes in 3ds max. OpenGL based applications will not work though, such as SolidWorks.

The last known "perfect" Quadro softmod on GeForce was 6 series. From 7 series onwards, you can only get a partially working Quadro by softmodding.

last good setup was when cards was not laser cuted

It's only theoretical fill rate and we don't know if GPU-Z actually calculates it correctly. I wouldn't consider this as 'working' if there aren't any improvements in professional 3D applications.

Run some pro 3D applications and compare, both D3D and OpenGL based and show us the results.

He meant the last good setup was when the cards were not laser-cut.

[Max_87]

I know, I just don't get what laser-cut has got anything to do with this.

[ChampionLLY]

I was wondering too when I saw the above posts, how's laser-cut going to determine whether the card can be soft-modded or not?

[generalRage1982hrv]

laser cut is done on gpus core to lock pipelines for extra shaders
on older cards you was able to unlock pipelines but now it just sux

I noticed that GPU-Z detects the device ID as 10D-0193 in the example, but then he selects a Quadro card with a device ID ending with 019E. How do you determine which ID is correct?

I ask because my card has an ID ending with 0400, but the closest Quadro card has an ID ending with 040A, if I recall correctly...
