After reading this article http://graphics.tomshardware.com/graphic/20041122/index... , and assuming that on most nforce4 sli motherboards its possible to set the motherboard to sli mode, then use the two 16x slot to connect some other 8x card like some serial ata raid5 controllers from areca or multi gbe cards, the next question is if a 16x card ( ofcourse not high-end, in the radeon x300 or nvidia 6200/pcx5200 league ) can work on a pci-express 1x slot? Reason i am asking is that the above setup, along with a dual core athlon64 makes a strong relatively low-cost server... one could answer that since its for a server, a common pci graphics card could be used, but in any case, pci-express 1x is faster, and node to node, so graphics wont stress the pci bus, slowing down other components that are connected to pci bus. in your review you mentioned you used a special bios to get the mb to work on lower pci-express modes.. that will be needed too in the case i am describing above?

It might work, but I've never seen an open-ended x1 slot. Maxtor makes an x1 card, better to choose that card in the first place.

I wouldn't worry about graphics stressing the PCI bus, because your display system will be in power saving mode anyway.

The funny part is that some people (read very few) have been able to 'mod' the physical connector and make it work, howver many people have attampted to match these results with bad BAD results, the most notorious of which was that on at [H] where the guy destroyed his GF6800GT to test the mod.

I agree, either getting a true PCIe 1X or plain PCI card is the way to go.

Yes, I've actually heard of x16 cards working in MSI's open-ended x4 slot, but not on x1.

@Crashman, about the Matrox, its expensive ( some googling showed prices to the $140 range ) and i would guess rather difficult to find it for sale...

@wusy, you probably refer to this http://www.overclockers.com.au/article.php?id=395983&P=...
about modding the pci-e 1x slot, it just requires to remove that part of the connector, with some dremer/little saw?
and there are no other differencies to a open ended slot? electrical etc?

Actually the one I saw was a GF6800 series (not sure if it was plain, LE, GT or what [doubt it was an Ultra]).
