Re:GeForce 9800 GT blocked in Dell, some BIOS to trick system? - 2008/08/30 11:44

It is a good read that should clear things up. Oviousley there will be some conflicts with backward compatibility, thats what computers do. The PCI Express 2.0 effectively doubles the bandwidth on a 8x slot! This is a fact that has been backed up by benchmarking.
I will repeat, it has nothing to do with the bandwidth and PCI Express 2.0 slots are only x16, so what the article shows is nice and great and somehow normal, but what you will find is current only x16 wide PCI Express 2.0 slots, and if you don't have that some video card will rely on that and won't work fine without it.
The card does work in the computer, it boots up you see the Dell BIOS screen, the loading of the SAS card, etc so that would tend to say that a PCI Express 2.0 card is compatible. Well some fun testing ahead of me tonight.
But you don't get past the BIOS boot, so that means at that time all the hardware is stil getting initialized and although you get the screen that is because at the start it just uses the standard VGA mode and after that the system will initiate the full graphics card functions and as far as that goes, it goes wrong there and your systems stops. So again, the GeForce 9800 GT really requires a fully PCI Express x16 slot which is what you can see as requirements set by NVIDIA and it has a reason...
