> Able to configure Quadro FX 4800 in SLI in Dell Precision T5400 under Windows 7 Ultimate 64-bit ?
I would be very interested in a definitive answer : Is it possible to configure a second Quadro FX 4800 in SLI on a Dell Precision T5400** under Windows 7 Ultimate 64-bit? Research indicates that I should see in the NVIDIA control panel a resident option to enable SLI, but this option is not available.
** [Xeon x5460 QC @ 3.16 GHz, 12GB DDR2- 667, FX4800 (1.5GB), WD RE4, Win 7 Ult 64, 875W PS. The current driver-(no. 4 tried) is 12/29/12 > 184.108.40.2060].
The T5400 when new (running Vista Business 64 bit) is specified as supporting the then-current Quadro GPU's, including the FX4800 inSLI
The Nvidia site has a listing for current SLI capable GPU's and mentions among others, a feature I would dearly like to have>
> ""SLI FSAA (Full Scene Anti Aliasing): Combines two PCI Express graphics cards with an SLI connector to transparently scale image quality on a single display by presenting them as a single graphics card to the operating system.
SLI FSAA increases the FSAA level up to 128x to remove jaggies from contours of geometries in real time.
Design review and digital mockup (DMU), visual simulation, and scientific visualization applications that require high level of FSAA will benefit from using the FSAA mode. [ > This level of anti-aliasing is one of the principal reasons I changed from a GTX 285 to the FX4800]

This is expected behavior with some of the older generation GPUs. These GPUs only support SLI under Windows XP, there is no SLI support under Windows Vista or Windows 7. Refer to the list below.
GeForce 6800 Ultra
GeForce 6800 GT
GeForce 6800 XT (formally known as V)
Quadro FX 1400
Quadro FX 3400
Quadro FX 3450
Quadro FX 4000
Quadro FX 4400 ""<END
Note that the FX 4800 is not in the list of no longer supported SLI GPU's.
Still, I don't see the SLI option appearing in NVIDIA Control Panel. I've seen a number of other posts to this effect, though none mentioning the T5400 and FX4800 specifically.
> Is it possible that the option does not appear unless there is a second card detected?
I was planning to add a second x5460 and more RAM as I'm working on a 6,000 part assembly in Solidworks and have 40+ large (1900 X 1200) renderings (probably in vray) of a 110MB Sketchup model to do. I should be very unhappy if my 2 year old, $1,100 new graphics card - which I specifically bought for SLI capability- is no longer supported in SLI.
P.S. The recent review/ tests / comparison of the Quadro K5000 this site was extremely well done and useful. Recommended reading for anyone debating Quadro vs. Geforce
