H i guys, I have Nvidia Geforce 8400GS 512MB DDR3 card,which they say is not supported the SLI technology. Can we make it out with upgrading the BIOS?
despite it is a CUDA compatible card (nice isn't it) it is not SLI compatible GPU and there is lack of SLI bridge connector (without bridge on hacked config you have very low performance). so: NO (bios update will not make it possible)
Hello, Seems you posted in the wrong forum. And no, your card does not support SLI because it has no physical connector for SLI
recently I noticed this link which says the specified card suppots SLI,from Nvidia!!! but the memory is 256MB. Is that anything useful to think off??? check this out http://www.nvidia.in/page/geforce8.html
http://www.geforce.com/hardware/desktop-gpus/geforce-8400-gs/features NVIDIA SLI Technology is not available on GeForce 8400 GPUs, however, 3-way SLI is available on NVIDIA nForce® 680i or 780i SLI MCPs and three GeForce 8800 GTX GPUs or three GeForce 8800 Ultra GPUs. It does not support SLI.
but apparently nVidia fail to mention the small fact on the web page for it's 8xxx series GPU's just which ones are SLI capable and which aren't The complete line of reality-redefining NVIDIA GeForce 8 SLI™-Ready1 Series graphics processors is now here.

SLI bridge wasn't required for SLI at the time the 8400GS was released. NVidia used to support a method of SLI refered to as "Software SLI" which didn't require a bridge. They removed the method from the drivers to prevent people from buying cheaper cards to SLI instead of buying more expensive single cards.
On this one no SLI connector, on some there was (those wich look like a 8500) , but it was the exeption that confirm the rule, and i guess it would be horrible performance.
