Why the thread still says "PCI-E Gen 2.0 Bug X38/ X48/X58"?
Good question donmarkoni
At the time this thread was posted there was an issue (perhaps related or not?) which meant PCI-E Gen 2.0 did not work on ANY non nForce based motherboard, however this WAS resolved and it may have only been an issue in one, perhaps two 190 series Forceware drivers. This is confirmed with PCI-E Gen 2.0 NOT working on a P5E3 Premium (X48) using a GTX 285 graphics card. And also not working on a Biostar X58A motherboard. However 195 Forcewares and newer appear to not have this bug/issue/lock on the X48/X58 platform, but the X38 is confirmed locked out of Gen 2.0 by nVidia t the moment due to a PCI-E Link pState "bug"
nVidia are considering making changes to their driver code to accommodate for PCI-E Gen 2.0 on X38 based systems and would like our opinions on the matter.
