SLI hack on Intel legacy chipsets (not X58)

[dduckquack]

nice to see this getting done finally

[ShArKo]

well guys....this is a great news But I got 2 cuestions.......

1 - Where are the drivers???? I want to test the drivers on my Maximus Formula X38...

2 - This drivers can work with Windows 7 x64 ???

I want to test it with 2 8800GTS 512MB (G92)

PS: If this work, you will make me so so SOOO happy :p :p

Just go and read first post in this topic, if you don't want to real last pages.

1. Shared.
2. No, but i near future maybe yes.

[ShArKo]

TiN_EOF the drivers 190.62 are normal drivers ? I just download those drivers from the NV web, install and put that "patch" and it gotta work? (in Win XP 32 bits) ???

[soundood]

TiN_EOF may i start by saying that this is some very valuable work here, and raise my hat to you,

now on to my question, if you can add the patch in post 1, that must have the x58 slic, can you make one of these for AMD chipsets? would it even be possible at a hardware level?

and if so, could you do it? because there are a tone of guys like me out there, running AMD boards, that have Nvidia GPU's that would love a bit of Sli Action.

thanks

[TiN_]

Yes, it's normal driver downloaded from NV. Just modified nv4_mini file to fool it thinking that we always have X58 chipset.

Full HOWTO will follow tomorrow. Already done in russian, have to translate

2 Moderator: Maybe it's better to move this thread to more suitable section? Don't know is it good to post and discuss all tech stuff in News

[ShArKo]

I got another cuestion jeje

Do you need the SLI bridge to enable the SLI ???? Or can work without the SLI bridge??

[soundood]

ok i dug out another card i have here (8500GT) and i am about to instal 32 bit XP on a spare partition,

i am going to follow the intructions and unpack the driver with winrar, and insert the said file, instal drivers, and see what happens.

and yes this is an AMD Cross-fire board, the M4A79-D to be exact, and i know it wont work, but hell god loves a tryer

i will report back my failure later

You will fail, if just install modded driver without DSDT registry patching.

I'm preparing HOWTO article...

My 6600LE worked too without bridge

[BrokenWall]

I wonder if this hack will allow us to have SLI on even AMD chipsets. Cause we all know we really don't want our Phenom IIs running on nv chipsets.

[Luka_Aveiro]

Sli works without SLI bridge, but the bridge performance increase is like 5% (10%) max, at least with 8800GTs.

[BulldogPO]

Yes it works.

i can confirm a fail, without the DSDT registry hack, i will be here waiting on your how too, and also have an XP 32 bit image waiting to be tested on

although one thing i noticed was a command prompt window opening during instal (twice) of drivers.

jhaving a look at the DSDT reg entry at the moment, cant wait for your 'how to'

DeDaL tested mod under my guide, with his Gigabyte X48 motherboard and two GTX 260's, everything worked so far.

I think, he will post details.

EDIT:

03 mark done, everything is ok

E8600 @ 4GHz, Gigabyte X48T-DQ6, two 260GTX 216sp

SLI - Disabled
51627
SLI - Enabled

All seems that it will work. Mod makes driver know that chipset is X58, regardless of real hardware.

[ChinStrap]

This will unleash a lot of performance; kudos man!

massman, will these drivers be postable @ the bot?

[Dr.Paneas]

AMD + SLI great news and many many many congrats to the programmer who finally made it true.

[Fungus]

This might be a silly question but... will tri-sli work? I have a 9800GX2 and a 8800GT (G92) laying around. This would be sweet! =]

If so, would my PCP&C 750 watt supply handle the load?

[davidkozat]

Hi guys just wondering 2 things, first congratulation about the hack SLI enable guys really well done so:

1. I always preferd SLI over Xfire but I have a P5Q Deluxe cso i like how it Overclocks my CPU so i was wondering if the nv4_mini works on my board.

2. And if it does would i have to get an SLI bridge for my particular MoBo or Graphic Cards i have a xFx GTX 275 and a spare 9800 GT

my mobo only runs 8x xfire and the gtx 275 has to sli connection but my 9800 gt has one so i dont think ill be able to get an adapter to connect both?? right?...

[BulldogPO]

How hard it is to make this Vista & Win7 compatible?

[sirheck]

Hmm??? So the old X48 is the new X58?
NICE!!!

[TiN_]

Different ID video's would not work.

Mod just removes chipset limitation, it's not miracle yet to make everything work with everything.
So only SLI-configs which can be done on "true" NVIDIA chipsets or X58 are possible yet.

Autotranslate from google of my step-by-step guide:

will workout it this evening. Now I'm goint to bed, no sleep to 50+ hours.

1. Yes, it will work, no matter what motherboard. But you also need to edit DSDT tables.It's still necessary.
2. No, 275 + 9800GT don't work now.

Please, dear ALL, understand that different cards would not work, it's way much complex to make it working , than modding chipset limit things.

So only legit SLI configs are supported, 2-/3-/4- ways which are working on "official" SLI systems.

[davidkozat]

dude both cards support sli but if i get what you are say is right you mean that only the same series card will sli aka 2 9800 or 2 280 or 3 8800 basicly the same card?... cool am gonna give it a go with 2 9800 gt that i got like 10 9800gt cos i work at a pc shop lol anyway ill let you know what happens mate

thank you for your work and patience

[davidkozat]

by the way when i modify DSDT tables do i use the steps used for the gigabyte board of the P5B one? i have a P45 chip after editing and restarting is the i apply the (http://www.xdevs.com/sli/Forceware_X...062_SLImod.rar - 79 MB, Windows XP 32bit) patch right??

[soundood]

sleep well TIN, and thank you again for this, i have been waiting all night lol
