Can nvidia lock out NForce4 ultra to SLI mods?

If you have a modded nForc4 Ultra-based mobo, can nvidia's future drivers ever disable SLI functionality?


the pencil mod turns your ultra chipset into an sli chipset (the current revision of ultra chipsets)... now if you bios detects it as an sli chipset and drivers already pick it up as such, could nvidia detect such a modification and disable sli in future drivers?


this is whats keeping me back from getting one of those DFI Ultra-D motherboards....


cheers

I don't think so. When you do the mod, the board essentially becomes SLI, and the drivers detect it as SLI.

No, the only difference between the current ultra and sli chipsets is that those two pieces are connected, so when you manually connect them you an nforce 4 sli chipset.

no! :p

what do i need to do and how do i test it? I don't have a 2nd vid card. Just curious if in the future i could use SLI.

UPDATE 2/05/2005: nVidia has acted to prevent, or at least make it more difficult, to mod the Ultra board to SLI. First, DFI has advised us, and posted on their website, that they will NOT sell the SLI bridge to buyers of the Ultra board. Second, nVidia has advised us that future shipments of the Ultra chipset have been modified so that the mod to SLI will no longer be possible. An additional side effect of this second action is that the "Dual Video" mode, which performs at about 90% of SLI performance levels, will only work with nVidia SLI drivers 66.75 or earlier. If you do a quick check of web driver postings you will see it is now very difficult to find 66.75 drivers. With a chipset modded to SLI the "Dual Video" mode worked through 70.xx versions of the nVidia driver. nVidia also made it clear they will continue to make driver changes to prevent functioning of any "non-standard" (8X/8X) operation of their SLI driver. This also throws into question whether the VIA "dual graphics" mode on the 894 Pro chipset will ever work with nVidia graphics cards. If you are interested in the current UT Ultra-D we suggest you buy one now if you can find it. Future versions of the UT Ultra-D will not have the same capabilities as a result of these actions.


Its going to be very hard to mod a Ultra board to SLI with Nvidia being harcore on preventing it. Enthusiastic are very resourceful people but I think this may be a too great a challenge. Considering their changing the Ultra chipset to further prevent the modification AND that the SLI bridge only comes with the SLI boards, unless someone can fake the bridge your much better off getting an SLI board. Especially considering you can get a ASUS, MSI, or GIGABYTE board for about $180. I hope this clears up the issue for you. Peace.

They will probably start using different packaging for the SLI chipset. It's not impossible to have it working though - if someone hacks nVidia's drivers. It would be 16/2 and not 8/8 though.

It would be much easier if nVidia just dropped the price of the SLI chipset so we can have SLI motherboards starting at $150.
