SLI with different cards

[helloWorld]

In order to install this correctly, should I uninstall/reinstall the original 290.53, put both the GTX 580 and 570 in, install the original driver and then the modified driver?

[Cold Storm]

It's probably best to do a fill driver sweep and then install the modded drivers. That way there isn't a conflict between the two.

[anatolymik]

it's enough to install original and then install modded driver. if you already have original driver installed then just install modded driver and reboot the system.

[helloWorld]

So SLI will still have the memory limitatations like the traditional SLI then? Like, even if my GTX 580 has 3 GB, I will still be limited by the fact that the 570 only has 1.2 GB?

For instance, when I had my 570 SLI, I was not able to use Danoc's FXAA Injector, because each card only had 1.2 GB, and according to Afterburner, a lot more VRAM was required, so my SLI would never work and my FPS would almost immediately drop to around 30 FPS. Whenever I disabled the FXAA Injector, the SLI would work flawlessly.

First off, awesome work anatolymik! Second, don't try to mix match different shader model cards as you will most likely get erratic behavior (7900GT+9600GT just as a quick example). Say you have an 8800GT and don't want to bios mod it, you can add a 9800GT(x) to it.

But it's worth to try. Nothing will damage the system

[newtekie1]

I'm so subbed to this!

No I wish I still had my GTX460s so I could try the GTX470 and GTX460.

[KingPing]

I have a GTX570 and a GTS250, i'll try this later. For Science!!!

[DeAtHWiSh]

I'm gonna try this ASAP.

I have a gtx 580 and a gtx 560ti.

[overclocking101]

ill load up a fresh windows and try it with my 560 and 8800gts 320mb, id try it on this windows but i've had way to much bad luck with windows and modified drivers.

Awaiting results dude!

Well it didn't work with my GTX570 and a GTS250

It also Proves what a money grabbing bunch of bullshits Nvidia are.(forceing you to buy matched cards for sli)
How many Nvidia card owners would have bought a second card to upgrade to sli (hi-bred sli) in the same way many ati owners crossfired mixed cards such as 6950/6970.
How many card sales did Nvidia/partners lose to ATI due to this
ATI/AMD knew their cards could do this and publicy acknowlaged and supported this and so they " MUST HAVE GAINED SALES"

SHAME ON YOU NVIDIA YOU DESERVE TO LOSE SALES

They have been losing sales thanks to contract with Intel being broken after Skt 775k, plus only being able to produce the NF 200 SLI bridge for both intel and AMD boards just to support SLI since Crossfire is all driver capability and auto supported by AMD and Intel chipsets.

okay i got them in now idk what to do after step 3

idk what UAC is

do i add the files to the Display.Driver folder or where

[eidairaman1]

UAC is user account control, its the lil prompt that appears before making any changes to the Operating system which darkens the background and you get a prompt asking for confirmation...

I doubt it'll work for my GTX280 and GTX570 then...

This is still huge!!

Any idea how it manages load balancing and differences in memory??
or does it run everything at the slower card's speed?

[Mussels]

really interested in results from people with mismatched cards and how it works (different DX levels, etc)

post a screenshot of nvidia cp. also go to c:\windows\system32\drivers folder (use native windows explorer for it) and find there nvlddmkm.sys file. send to me this file.

unpack DriverWinVista7x64.zip file. go to DriverWinVista7x64 folder. run install.cmd. reboot. that's all

[ViperXTR]

if only i have a 2 slots for graphics card, i would have tried this on my idle 9600GT lol for science!!!
