where do u find the NVapps.xm_ under the 163.76 drivers i dont see it...

every driver release will have 2 .xml files

if the files are uncompressed versions the file extension will be .xml

if the files are still compressed they will have the file extension .xm_

the newer driver versions have 2 xml files:

nvapps.xml

nvwsapps.xml

copy those 2 files from the very latest driver releases (to get the most upto date profiles) and copy and overwrite into the driver set you wish to use, then install as normal.

not always :)

Exceptions happen sometimes when 3rd party driver sites unproperly pack drivers.

I cannot count anymore how often this occured with guru drivers in the past. And even NVIDIA once made a blunder here too :)

What happens here then is, you will find two xms files :P Which obviously will result in a total messed up driver installation as no game profiles (and no application) will be available. Earlier drivers which came with cfg files were also affected.

rock direct i think. they are pretty good too, not alienware though :)

I got my sli working on vista using the alienware beta driver. it just popped up after a reboot and asked "wanna enable SLI?"

Which I replied "Hell, it's about time!" :P

and for those wondering: I DO feel an perfomance boost. so its not just a fake SLI.

good luck mates

Any chance of getting the Alienware beta? The Australian Alienware site doesn't provide online access...and are a little slow to render assistance.. :P :)

can everyone with a SLI setup run the latest GPU-Z and let me know if your GPU's have identical BIOS versions?

For some reason my 2 Go 7950 GTX's have different BIOS revisions in my m9750

one card is showing a BIOS version of 5.71.22.49.23 and the other is showing a BIOS version of 5.71.22.49.22

I've emailed Alienware asking for clarification on this and asking if .23 is the most upto date BIOS.

will let you all know when i get an answer

My cards are showing BIOS revs 5.71.22.49.23 and 5.71.22.22. Just for the record I'm able to install the modded 163.76 XP drivers from this site just fine. They seem to work just fine for just about everything but they have the same issues the stock Alienware drivers have with flickering textures in Guild Wars. Other than that though I've had no problem with the 163.76 drivers under XP; haven't tried Vista yet though.

The different versions, in this case just 1 number is probably to distinguish the GPU's to the BIOS.

If they were identical they would probably not work at all in SLI, as each will be doing the same thing at once, or trying to.

Each one will probably have a slightly differnent susbsys number (or it could just be the BIOS version) to tell the driver there are 2 GPU's and to try and enable SLI.

ah well that would make sense then if the driver was looking at the BIOS numbers

No. The drivers do not use BIOS versions to distinguish between cards, each card has its own PCI/PCExpress identity in the system determined by its location on the bus. BIOS version plays no part in this.

Only way to find it is to grab both BIOS's and compare, other than the revision number difference they should be identical ?

With 2,33 GHz T7600, 2 GB RAM and 2x Geforce Go 7950 GTX Alienware m9750 im only getting 7296 with 3D-Mark06... =(

what image quality setting have you got set in the nvidia control panel?

High Quality, Quality, Performance, High Performance

i got my 8822 score with it set to high performance, looks like you might have yours set to High Quality?

run 3D Mark 06 on each of the performance settings above to see the spread of your score, this will give you a feel for how each one adusts your overall framerate depending on how good looking you want your games to run.

got a response from Alienware on the variation in BIOS numbers:

Dear Leon,

Thank you for contacting Alienware.

The different video BIOS versions are meant to be installed like that; otherwise, the laptop will not even post. Due to its design, this system requires a daughter and parent video card and each has its video BIOS version, they can even be told apart because of it:

DAUGHTER VBIOS: 49.23

PARENT VBIOS: 49.22

Yes, im using High Quality...

Now I use 156.73 and I got 7339 points! =) (without SLI something about 4500)

i found a Clevo INF for 156.55 XP with lots of subsys IDs and repacked and reuploaded the driver.

Unfortunately, it looks like the m9750 SUBSYS (at least for my system) is 2052161F (0297&SUBSYS2052161F to be exact).

I'm guessing it won't work, but I will still try it.

This is extremely frustrating. It really irks me that we spent all of this money on an SLI-capable notebook with the best cards (at the time) and it's feature "locked" due to outdated drivers. Putting pressure on Alienware has only prompted them to release a Beta driver for Vista users (seeing as I have an m9750 with dual 7950 GTX, Vista will be a last resort due to the stability of running in XP). It seems that they will not be providing a further driver update for XP SLI users, and only for Vista SLI users.

So far, I've been able to circumvent a majority of the issues by downloading the latest official nVidia Betas and using their Nvapps.xml and Nvwsapps.xml files with Alienware's 94.23 driver. The added profiles help with improving performance with most games, but it's obvious that there are overwhelming limitations due to the chipset for us SLI owners. It's not just an SLI issue, as using this feature to play new games with SLI disabled doesn't yield the performance result that it should (i.e. minimal improvements with Crysis, World In Conflict, and COH:AF).

With the release of the 8700-SLI GPUs in the latest m9750, it seems that they'll be focusing on Vista drivers, as they'll be little care to cater to us 7-series XP users. The responses from Alienware support (US) have been unhelpful, and I was even advised at one point that if I simply "upgraded to Windows Vista" (i.e. paying them more money), I could avoid the issue and receive faster and more reliable driver updates (but at a performance cost, obviously, since Vista is still in the early stages). Ain't that some ****?

UPDATE:

http://forum.notebookreview.com/showthread.php?t=185060

I recentlhy stumbled accross this fix, and it seems to work. It involves downloading and installing the latest drivers along with the modified .INF file from LaptopVideo2go, but seems to solve the problem of the Black Screens with an easy fix:

1) Download the driver you want along with the modified .INF, and replace it (I used the latest 169.04 XP 32-bit "Crysis Demo" Beta drivers).

2) Uninstall old driver, reboot (preferrably use Driver Cleaner Pro in Safe Mode).

3) Install new driver BUT when it goes to install the second card (i.e. The 2nd Continue/Stop installation prompt), STOP THE INSTALLATION FOR THE 2ND CARD.

4) Reboot.

5) Navigate to the Device Manager and notice the second card is uninstalled. Update it's driver by manually selecting the driver folder for the one you just installed.

6) Reboot.

7) Voila!!! Successfully installed drivers.

If you were using Alienware's 94.23 drivers, you'll notice that you have full access to the nVidia Control Panel and SLI works just fine once you enable it. I ran 3dMark06 using the 169.04 XP 32-bit drivers and scored 8816! The Crysis demo showed only an improvement of 1 FPS, but had less random freezing, and most importantly I noticed improvement in just about ALL of the other games I tested (COD4 Demo, BioShock, Battlefield 2142, World In Conflict, Unreal Tournament 3 Demo, Medal of Honor: Airborne).

This easy trick fixes all of the Black Screens that occur from attempting to install drivers the usual way. I do not know why it works, but it does. I haven't got a clue as to why you must install any non-Alienware driver one card (i.e. one boot) at a time, but hey, I'll take anything I can get. I haven't tested this on any other drivers, but according to a couple of other testers, the following drivers successfully worked, all tested in XP with 2x7950 GTX cards - 163.76, 169.01, 169.04

My m9750: T7600 C2D, 2 GB Ram, XP Pro, Dual 7950 GTX 512.
