Hi

I'm updating my self, lol, yesterday didn't had time to fool around with SLI testing. I will test, sure.

Now: I was reading the latest post and I don't know if it help:

Supermicro C7X58 SLI Certificate:

Code:

    Scope (_SB.PCI0)
    {
        Name (SLIC, Buffer (0x9E)
        {
            "987134512781Genuine NVIDIA Certified SLI Ready Motherboard for SUPERMICRO X8SAX    0101-Copyright 2008 NVIDIA Corporation All Rights Reserved-765289891023(R)"
        })
    }

    Device (_SB.PCI0.WMI1)
    {
        Name (_HID, "pnp0c14")
        Name (_UID, "MXM2")
        Name (_WDG, Buffer (0x14)
        {
            /* 0000 */    0x3C, 0x5C, 0xCB, 0xF6, 0xAE, 0x9C, 0xBD, 0x4E, 
            /* 0008 */    0xB5, 0x77, 0x93, 0x1E, 0xA3, 0x2A, 0x2C, 0xC0, 
            /* 0010 */    0x4D, 0x58, 0x01, 0x02
        })
        Method (WMMX, 3, NotSerialized)
        {
            CreateDWordField (Arg2, Zero, FUNC)
            If (LEqual (FUNC, 0x41494C53))
            {
                If (IFSL ())
                {
                    Return (SLIC)
                }
            }

            Return (Zero)
        }
    }

9800GTX SLI on a Rampage Formula

Hi guys

I gave the guide lines that aGeoM gave in post 923 a shot with my Rampage Formula and some XFX 9800GTX Black Edition


It worked the first time, really awesome, rather easy to implement it too, thanks guys for all the hard work you have put down.

I have to register to this forum so that I could thank you all, you should have all the credit there´s, much appreciated.


Only thing I have noticed so far is that the fans do not go down after a 3D app is done, they still at the same rpm as at full load. Someone else have that issue?


Here´s some screenies



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

SLI



A quick test with Stalker Clear Sky, same setup.

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

What are we testing? HALmod with DFI cert and unmodded drivers? Or ASUS cert?

Thanks

 

WITH ASUS CERT + HALMod + UNMODDED DRIVERS

 

can you mod them so i can make use of more than 4gpus in sli?

 

but at first try v0.71. if it doesn't work then try v0.7

 

did you try 4 gpus?

 

yes. works fine.

any more and the option changes to

"enable quad sli"

and

"physx enabled on _______" (the 5th card)

im wanting 6 card sli though so i can use 3 295s and eventually 3 395s

 

is there officially more than 4 gpus?

 

no. you can sli 2 295s or 4 evga classified 285s.

no other combos atm

 

then no. i can't write driver for this cards instead of NVIDIA.

 

its not just a simple limitation that can be removed im guessing.

 

it's hardware limitation i think

 

how about SLI physx?

would it be possible to have 2 cards dedicated to physx?

 

i think not

 

im i just asking for something so crazy that its not even worth trying?

or is it just not possible unless you have a desk in the nvidia dev lab?

 

Rev2 for W7 x64, yes, yes.

Yes

 

I will give it a try when I have more time, maybe later tonight.

 

TheWolf try my last HALMod please

 

thanks

 

OK test done.

HALmod v0.71 + replaced modded 190.62 nvlddmkm.sys by original +ASUS cert = SLI enabled

HALmod v0.71 + Clean install Unmodded 190.64 + ASUS cert = BSDO on detecting hardware, did 2 install method setup/device manager

HALmod v0.71 + Clean install Unmodded 190.62 +ASUS cert = SLI enabled

 

thanks. about BSOD if you have SLI patch enabled and place original hal.dll on its place, after reboot you got bsod.

 

I didn't place original HAL back on. The BSDO happened during driver instal.

Gonna test 191 WHQL drivers now.

BRB

 

post results please
