How to enable SLI on a 9800GX2?

[Toxcity]

Right, I have a 9800GX2 sitting in my PC right now.. and for the last day I have been only using one of it's two chips.

The main reason for me thinking this is because of the performance gain I have got.. not alot.

Plus GPU-Z says SLI Avalible but disabled.

Any ideas?

The control panel comes up with nothing what so ever.

Picture of the CP? Make sure it's in advanced mode

There you go:

It's not detecting your GPU properley

Suggest you uninstal and re-install with the latest drivers

I assume this in WinXP?

Windows Server 2003 x64.

Ill go grab the latest drivers and reinstall.

Is SLI compatible with Win2k3?

Cannot see why not? Same kernel as XP 64.

Just done a reinstall and it still hasn't appeared.

I can now confirm that SLI is not supported at all in Windows 2000 or Windows 2003 Server. This is not a bug. This is the case for drivers newer than 96.xx. SLI was never supported in any OS older than XP but the option was there. NVIDIA finally changed the drivers by removing the SLI option because. although the SLI was not supported, the option was there. That caused problems because naturally people were enabling that unsupported option.

I'd say it doesn't look like it is supported

 

[Toxcity]

Awwh god dammit.

 

[FarFarAway]

Just use XP? It's not exactly a whole lot difference to 2k3 and certainly gaming performance is identical

 

[Toxcity]

Just N-lited XP.. and moving to it now.

Thanks for the help Kemp.

 

[Toxcity]

Right, now on XP.. and running well.

SLI has now popped up. Damn Nvidia.

Oh well, cannot complain with an idea ram usage of 73mb.

Holy

Damn, Vista 1gb idle here?

So? It really doesn't matter tbh, Vista dynamically assigns RAM when it's needed and uses it for system idle processes when it's spare

Word.

I'm close to 2gb usage but it doesn't matter because of the above point

 

[FarFarAway]

Aye Im on 1560mb usage but it clears it out when you play games and assigns whatever the game needs for gaming.

 

[Bungral]

And what's the point in having 4gbs if you are only gonna use 1.5gbs of it?

 

[Hatman]

Well the more you got in total the more it like, reserves. I found it a lot smoother from 2gb -> 4gb..

Nvidia does not support SLI under Windows Server 2003. Sorry.

You can get SLI under Windows Xp Professional x64 Edition, though.

And since XP x64 SP2 is really just Windows Server 2003 R2 SP2 masquerading as a desktop OS, go use that.

Just be sure to use the 174.74 WHQL drivers or you'll have all sorts of wacky issues with it.
