Can you still mod a DFI nF4 Ultra-D to SLI?

Supposedly you aren't able to do so anymore, anyone confirm this? Think I'm gonna buy an Ultra-D from Monarch

Thanks

Yeah, the same for the Neo4-F, you can still do the mod physically but nvidia's newer drivers won't let you use SLI on them . . .

See the detailed instructions for the modification at DFI Street where the author (in his updated instructions) says:

"Now I can already hear you thinking that you would love to do it but nVidia will change the drivers to block SLI on an Ultra chipset.

That can not happen. By performing the mod on the chipset you are turning the Ultra into an SLI. This is a physical change that no driver in the world can detect. Once you close the contacts on the Ultra chipset it is now an SLI chipset.

There are absolutely no driver issues involved since the chipset will now be as much an SLI as a "factory" SLI chipset."

While I think it is still possible, it will be tougher now. On my october purchased dfi nf4 ultra-d, the two contacts that you need to mod are filled in with non-conductive epoxy.
