GeForce to Quadro modification Guide

On a gamers' point of view, there's no use to modify their GeForce since most games won't take advantage of its extended capabilities....but you still get a higher core frequency (135Mhz vs.120), a higher mem. freq. (333 instead of 300) and the Sideband addressing enabled as default. 

And there's still one good point : 
If you flash Silicon Graphics' BIOS ( http://support.sgi.com/nt/product/330/ VR3 is for GeForce DDR and V3 for SDR), you can use their optimized drivers...same story with ELSA and their cracked drivers, available at http://zoiah.m3dzone.com

Hope this helps...

If you compare the 6th line to the 8th, you can see that a modified Geforce 1 can beat a GF2 GTS when using professional 3D applications.

One more time...the Quadro results are still far better then the GF2GTS'

User Comment:

Hi Patrick, I really found your article on converting the GeForce very
informative, best I've read so far, I know very little about the technical
side of setting these card up but I know a bit about electronic hardware as my friend and I design and build miniature electronic devices.

The mod instructions are very good but I would strongly advise anyone doing this mod to buy and use new resistors which only cost a few pence/cents.

The reason is that it is very easy for solder to contaminate these tiny
resistors when they are removed, it's good practice to discard them and fit new.

It's possible for a fine thread of solder to bridge the contacts on each end
during removal thus changing the value from say 10k ohms to virtual zero with possibly disastrous results.

Also before replacing the resistors the pads and surrounding tracks should be examined with a strong magnifying glass to ensure no bridging with solder has occurred during the removal process.

We use a stand with an adjustable magnifier which I bought off a cheap tools stall in the local market for £2/$3.

It's also important to use a grounding wrist strap to remove the risk of
static shock to the card when handling, I use one for peace of mind!

When you look at the picture, you can see damage to the PCB surface and artwork local to the mod, any stray solder or damage to the tracks due to using pins etc to prise off the resisters could kill the board.

Also prising up the unsoldered end of a component can cause the other end to lift the pad off the board surface easily resulting in an invisible break in the connecting track, the card won't work and you can't see why!!

Don't get me wrong I'm not saying you didn't do it properly, I'm trying to
warn others that these surface mount components are difficult to handle as they are really meant for robotic assembly, perhaps something like this could be posted.

Thanks for a good article.
