SLI hack on Intel legacy chipsets (not X58)

[tpp]

I tried it and it seems to work, run 9800GTX SLI on a Rampage Formula.




A quick test with Crysis, Rampage Formula / Q9650@3,0GHz / 2x2 OCZ Blade LV PC-9600@1066 555 15

Hi.Ghostleader

How can you solve the problem? could you tell me?
}} to }) or not

thank you

Will it work on P35 mobos?

[BenchZowner]

Will it work on P35 mobos?

It does.

[ShArKo]

So the think is.......download the 190.62 driver from nv web. Download the nvlddmkm-64bit_rev_2.rar file (to Win 7 x64).......I put the file on the system32 directory and thats it???
I do this cuestion again because the thread is a little disordered for me. Maybe someone can put the hackfiles for 32 bits and 64 in that way it can be more ordered!!!
And we can do a list with the one who make it work. What chipset use, what DSDT file use and what performance gain!!! (Is just a thought)

Well, I really don´t know because I used an other way, insteed of copy, paste and compile I used the "sli string installer", just start the this little app and choose which brand you mboard have and thats it.

Looks like this




I used aGeoM (from techPowerUp forum) guide.

Hi

I just did a clean OS install, this was what I had to do:

Motherboard DFI LP DK 790FXB-M2RSH (0820a)

1 - Install Win7 x64.
2 - Install System and 190.62 Win7 x64 (WHQL) drivers.
3 - Disable UAC.
4 - Restart.
5 - Run SLI string installer as Admin select ASUS certificate.

It's patched driver Windows 7/Vista 64bit for Forceware 190.62

You need to have ASUS valid SLIC in DSDT.

Reboot, and enable SLI.



(Make sure you are using an ASUS SLIC)

Shouldn´t be a problem with your board, just do as the above guide says, it´s rather easy I must say, the things is that you fool the Nvidia driver to think that you run a X58 chipset. (check below with CPU-z)


Here´s some more Crysis tests, pretty good I most say.

So what method is best for Vista X86?

Nice work , I might give it a try on my RE also

I noticed that it show X48 chipset in your CPU-z motherboard tab, in mine it show X58. Which HALmod and slistringinstaller did you use?

You´re welcome

Nice work

I noticed that it show P45 chipset in your CPU-z motherboard tab, in mine it show X58 and in my CPU-z memory tab it´s all clear. Which HALmod and slistringinstaller did you use?

Only thing I have noticed so far is that the fans on my 9800GTX do not go down after a 3D app is done even though temp is going down, they are still at the same rpm as at full load. Someone else have that issue?

[anubis_is_evil]

is there a side effect for doing this driver hack for using SLI on Intel board..?

perhaps, northbridge can run much hotter, or something else...

thx...

[TiN_]

No, why? Physically load using SLI isn't differ much from two separate videocard setup. PCI-express hub will be hotter, but only few (1-2-3-4 or so) degrees more, just because of more bad airflow. If you use SLI bridge, than no difference at all, I guess.

ow, oke than, afraid its going to be like that nvidia chip that comes real hot

i really should try this, must find another GPU right now..

thx man

[Proday]

Tnx to all who made this mod! And I have to ask, is it better 260gtx or 8800gts 512 SLI?!

[BulldogPO]

2x 8800 GTS beats single GTX 260.

[K404]

Has anyone hosted the crack files anywhere else? I *think* some of them have been pulled from the TPU site

I have the SLIStringInstaller but nothing else. Im hoping to give this a try "openly" I dont want to be tied to a 190 driver


As others have said... thankyou to the guys who have put the work in

[Talonman]

The GPU's still need to match, correct?

This isn't a wild-card that would let me run my 295 in SLI with my 280 is it?

Ey guys I need some help here!!!

I try to do the Windows 7 64-bit, method 1, modded Forceware 190.62 Vista/7 x64.

I Try it from here: http://xdevs.com/e107_plugins/conten...php?content.30


I do this:

Dowload the SLI String Installer and put the ASUS option. I download the modded drivers 190.62. (This drivers is the same for all O.S ?? ).
I unzipped this drivers on the dafult folder from NV path...
Then I instale those drivers and reboot the system. I got some problems with some games like COD2 and SF4 :s :s Im doing something wrong?

2x 8800 GTS beats single GTX 260.

barely if not equal...even if they beat it slimly.single gtx 260 is less psace,heat,power,and can alway add another 260 for $150 more later...sell those 8800,s for $150 both before there were nothing and buy a single 260...futureproff your rig.
