Unable to find PCIe 1.1 Video Card

Hello,

I'm looking for a PCI-e revision 1 or 1.1 video card for this Intel DG41RQ motherboard.

 

Specs here - http://www.intel.com/support/motherboards/desktop/dg41rq/sb/CS-029923.htm

 

I can not for the life of me find any video cards that use PCI-e revision 1.1, the lowest seems to be PCI-e 2.0.  Is PCI-e 1.1 also considered 2.0?

 

Thanks for any help on this!

I would have thought that since the motherboard is 1.1 it would only support 1.1 or below.  This is not the case though?  And if so, can I purchase a PCIe 3.0 video card?

 

A PCIe 3.0 card would work but not at its full potential since the bandwidth of 1.0 is significantly lower than 2.0 or 3.0. It's very likely that a modern 3.0 card would be bottlenecked by older slower components.

This. It wouldn't honestly be worth it unless you plan on upgrading the motherboard, CPU, maybe the RAM and maybe the PSU too if it's too weak too at some point.

Chances are if the machine has a PCI-E 1.1 motherboard (like mine), it's very likely it also has DDR2 RAM in there. Which by extension would mean the RAM would also have to go when it's time for a new build.

 

In my case, for example, I have a GTX 670 which is a PCI-E 3.0 card, and despite that I still have appreciable gains over my previous card.

Yes, PCI-Express is both fully backwards and forwards compatible (faster cards work in slower slots and vice versa), you can use any PCI Express card you want. It would of course be limited to your 1.1 slots interface speed as mentioned but it will work fine, just slower.

Though, in theory cards should be backwards compatible from 3.0 --> 1.0 in practice that isn't always the case. Sometimes, newer cards just won't function in 1.0 slot. I'd personally only go for a 2.0/2.1 card given that. You stand better chance of the backwards compatibility panning out if you do that.

Sometimes a 3.0 card will have trouble working in a 2.0 slot as well. I had to do a bios update for my motherboard to get my 7850 to work with my board, for example.

That's a good point, most of the time it probably is an issue with the mobo when there are issues and for that reason you are much less likely to see updates to fix issues if you are spanning multiple revisions. I.e. it's probably more reliable to go from 3.0-->2.0 or 2.0-->1.0 than from 3.0-->1.0.
