SLI with EP45 DS3r Gigabites

Hi to all
that mobo is designed for Xfire ( ATI), actually it's running with a 9800GT
POW on 16x PCIe, can i plugg another Nvidia 9800GT on the second PCIe ?
Should this work on SLI or not ?
Thanks for help

AFAIK, only Nvidia chipsets support SLI. The EP45-DS3R has the Intel P45
chipset so I don't think it will work. You might be able to have two cards
installed but they will act as two independant cards and you would see not
benefit in terms of performance a al SLI or Crossfire.

Your mainboard uses an Intel P45 chipset. The nVidia graphics drivers will
not support SLI on this chipset.

nVidia has not, in the past, permitted SLI on systems with Intel chipsets.
The exception was the rarely seen Skulltrail mainboards (X5400 chipset, dual
Socket 771, but with nVidia nForce PCI-E controllers). Some of the latest
X58 mainboards (Socket 1366, I7 CPU) have been approved for SLI by nVidia,
if the mainboard maker paid a licensing fee.

You could plug in a second graphics card, but not for SLI.

You could do CrossfireX with a pair of ATI cards, if you like. The board
throttles back to PCI-E 8X if both slots are used, so the CrossfireX
performance may not be as good as a board that can run two PCI-E X16 slots,
but I guess that it'd be OK.

Can't do XFire, but you can still do dual display cards (4 monitors),
and you should be able to utilize the 2nd card as a dedicated Physx adapter.

Ok, thanks for reply
