SLI with different cards

[cyberphy]

Is it possible to SLI a GTX 1050 and a GT 730?

 

[CommanderLake]

Legend has it in you look in the mirror and say SLI 3 times the hexadecimal offsets show up on the mirror. Don't believe me?
Proof:

430.86
=====================

000000000027E872: BA 00
000000000027E873: 6B 00

Offset for 430.86 Windows 7 version begins at 25C9A5.

We may have a breakthrough!
I just replaced every instance of 0F BA 6B 24 and the following byte with 90's and the driver works and I get an SLI option but with a GTX1080 and a Quadro P4000 I get a BSOD, could anyone with some other combination of cards test this?

DO NOT DO GLOBAL REPLACEMENTS LIKE THAT.

You messed up a bunch of routines of your driver so naturally you will BSOD. Never blindly patch code like that unless you know what you're doing.

Holy crap calm down, I'm not the one who started all this driver modding.

Has anyone gotten this to work on a supermicro h11ssl-i motherboard? It's an AMD epyc build.. so I know I have the pcie lanes. I've installed everything correctly 3 or 4 times, maybe it has to do with windows 10 pro?

 

[P!nkpanther]

With the launch of the RX 5700 XT, having good price/performance but lacking crossfire, could this trick be used with these cards to have four of them working together?

Using a patched nVidia driver on an AMD card?
AMD Navi actually supports CrossFire in explicit multi-GPU mode in DX12/Vulkan. Just not in implicit mode (legacy stuff using DX11 or less).

...trying to SLI two 970s one from zotac one from gigabyte. They both are at the same clock and everything has been updated driver wise but DifferentSLI Auto doesnt work. None of the stuff ive tried works to get them to run in SLI what should i do?

It probably works using the old patcher/driver (1.7.1 & 388.71), as outlined in this post (start reading below the video):

Nope. Different microarchitectures

 

[Arkanggel10]

hey guys, can anyone provide some tutorial for the 430.86? i am trying to get it to work but without success

 

[P!nkpanther]

It's basically in this post:

SLI with different cards

yes, when i look at the certificate in the driverstore it changed to differentsli and there is no error during the install script, and by the way, if it not copied i think it not say you than your system is sli capable and you not have the option to switch in sli performance mode

www.techpowerup.com

Remember that this new method no longer supports different cards.

 

[Arkanggel10]

I have one gtx 680 and 670, i cant sli them with this 430.86 verison?

 

[P!nkpanther]

I have one gtx 680 and 670, i cant sli them with this 430.86 verison?

Nope, the 'new' method only bypasses the MoBo compatibility check, but not the check about different cards.

You need to use the old patcher/driver (1.7.1 & 388.71), as outlined in this post (start reading below the video):

SLI with different cards

Okay, so the steps you explained above should work for 388.71?

thanks for the help pink

@Pretentious

Can we get updated offsets for 430.71? Please

 

[FractalParadox]

@Pretentious

436.02

Sorry Typo on the driver version number and I can't edit my old post for some reason.

update:

Good day! My attempt with 418.81 drivers was also unsuccessful; offsets were used for different video chips. Please tell me what can I do wrong?
UPDATE: the error was found, I will highlight in red what was not written to the 418.81 driver. But performance is very frustrating.

Hello all.. I have an issue I not able figure out.

My monitor is saying no hdmi connection on both HDMI port and on my spare tv is the same issue.
I tested both TVs with a virgin media v6 box, a free sat box and the monitors show picture fine on tv's.

I have 3 NVidia GeForce cards, 1. 560 ti - 2. 560 super clocked - 3. 540 ti.

each and every card worked fine before..

I have a spare pc and tested all the cards and the same issues on both TV's. I have many adapter's and HDMI cables tested all fine.

My pc powers on, I strip down the pc and rebuilt it, I am very pc technical minded, but for life of me I look all around the net and have I kill the switching over chips on the 3 cards ?

I did a dual graphics configuration with onboard Radeon graphics and a GeForce expansion card added to the pc/system, installed all the drivers...
on the outboard graphics only the vga port is working on the TV's - only with the ati Radeon card. not any of the GeForce cards working on either... vga - or HDMI still blue screens on both tvs.

next step: was to load up GPU-Z_ASUS_ROG_2.24.0 the ati Radeon has all information in text boxes, now I switch over to the GeForce card, now it says vga compatible card, no bios string, no gpu clock , no memory clock ect.

another step: I load up HWiNFO64 go to GeForce card has a bios string of the cards and load over information showing up..

I never have had were I can not get both my pcs working on hdmi ports.. anyone can help me.. I order 2 new cards and will test pc in the week as don't know what else I can do..

White pc is only working on the out board ati Radeon . not working on hdmi. not working with 3 GeForce cards..
black pc has no outboard graphics.
not working with 3 GeForce cards..

both pcs were fine over day and switch on pcs, blue screening . weird issue never encounter before ..

@Zabi
Cards without an SLI bridge are known for bad SLI scaling, even more so if your second PCIe slot has only PCIe 2.0 / x4
And some of the bad results are also due to some games themselves, which do not work well in SLI.

@sabre
Your post is very hard to understand to me. You describe the symptoms, but not what you have done with your system.
Looks like a blue screen on boot, which means HDMI seems to work fine, but you may have a driver/hardware error.
Does it have anything to do with the DifferentSLIauto patch which this forum is about?

It was hard for me to understand the issue as well as try explained what's the matter with TWO computers.

I use my black pc sli with
DifferentSLIauto patch.... every think was fine and working with this computer.
I am not getting a signal from both the graphics cards. hdmi, dvi. the cards have their fans spinning around.

The pc boots up, the harddrives spin round.

Ive taken Bios out the ram, clean and rebuilt the pc. I didn't do anything ! that's the whole point for some odd reason my cards stop displaying.

I use my white pc just for light multimedia use. on the same very day my black pc went down also
for some odd reason my cards stop displaying on this white pc and all that works is the VGA output on the onboard graphics. no hdmi working, no dvi working.

The 3 GeForce cards were all working and I can not now get signal output from any of these cards I own.

Just uncertain why I have no display, using windows 10 both pcs.

So what I am doing is fitting new cards in my black pc soon they come and be sli with
DifferentSLIauto patch
if my system display fine and works. then I kown it all my 3 cards are dead.

Update. just received mini - hdmi cable now . before used dvi on all pcs. My black pc displaying output with the new
mini - hdmi cable . yes happy can start to test system - cards - outputs.. woohoo.

so further testing to do and see if all cards still working, check dvi to on cards.

 

[Himbeere]

I know, its a bit old but @Pretentious can u please upload the hex strings for Nvidia driver version 342 i would highly apprechiate it mate btw. know you from Linus

 

[sabre]

with some testing of the 3 cards all dvi's on all cards stop working.

Ent a clue why that is, have many cables and adapters.

all work 3 cards work with the mini hdmi cable.

Now, i can suggest to anyone with difficulty's use a mini hdmi on cards if you have same problems as I did.

My setup.. what I used and power supply.

The GeForce works in Sli with... 1. 560 TI - 2. 560 super clocked withDifferentSLIAuto1.7.1 and
DifferentSLIAutoLoader and 391.35-desktop-win10-64bit-international-whql.

Used a
kl-c700 kolink core atx power supply series.
700w output.
all fine, games work great.

The 540 don't work with both 1. 560 TI - 2. 560 super clocked. The pc would just crash out with DifferentSLIauto patch and system rebooting.

New setup.

2 gtx 580.
kl-c700 kolink core atx power supply series.

got into about 1hour of gamming with wildlands game and the pc had reboot itself and the power supply fan stop spinning around. power supply gone dead.


So I order...
Novatech Power Station 1000 Black Edition 1000W Modular ATX Power Supply.

hope it does the job on my small buget.

I think it's more of a Compatabilaty issue than PSU problems.

I get this error in install.cmd. Help?

The process cannot access the file because it is being used by another process.
        0 file(s) copied.

EDIT: Fixed it

 

[P!nkpanther]

install.cmd has to be run in safe mode.

Follow the instructions or your chance of success is low:

SLI with different cards

This new patch does no longer allow for SLIing different cards. Instead of 'SLI with different cards' you might call it now 'SLI on any MoBo' @P!nkpanther We can happily say again that SLIing same type of non-SLI GPUs is possible, that too on latest drivers. This means GT 1030, GTX 1050, GTX...

[RafeeSamith]

I did run it in safe mode but that didn't work, It worked after I disabled the GPUs in Device Manager. Thanks for the help though!

Hi there! Managed to SLI 2x970 (with SLI bridge) on Windows 10 2019 LTSC, driver ver. 417.71.
As I know F1 2018 and 2019 is SLI supported, but unfortunately I've got lower fps in SLI mode (with 99% usage on the 1st card, and about 70% on 2nd one) .
Also benchmarked Unigine Heaven 4.0 with extreme preset on 1080p and got around 100fps/2500 pts, GPU scaling while benchmarking was 95-99% on both cards.
Any thoughts on this? Maybe this is low wattage PSU problem? Maybe I should try 3xx drivers or even Win7 install?

Thank you in advance!

P.S: my rig is i7 2600, Z68 motherboard (pcie 2.0 x16/2.0 x4), 520w PSU.

For some magical reason with the 430.86, Windows 10 and two GTX 1060 (NO P106) it doesn't work for me.
Steps I did
1. Locate the nv_dispi.inf_amd64_b49751b9038af669 folder.
2. I replaced the offset in the file correctly.
3. Error proof mode with network functions.
4. Run the install.cmd (where I replaced the folder name).
5. It was signed well and gave no problem.
6. Restart

I open the nvidia control center and I still don't get the option ...
somebody help me...
