PCI-E Gen 2.0 Bug X38/ X48/X58

Thanks STEvil

By design Maxforces nVidia cards with variable pStates are supposed to run @ PCI-E Gen 1.x when the card is idle and then switch into PCI-E Gen 2.0 mode when any load is put onto the card, sadly on the X38 chipset there is some sort of "bug" which causes alleged stability issues when a card switches from Gen 1.x to Gen 2.0 mode. So nVidia chose to lock the cards @ Gen 1.x mode regardless of how much load was put onto a card.
If you are not convinced I can post a picture of a GTX 480 running Furmark for more than 5mins yet still locked @ PCI-E 1.x (this was kindly posted by someone who suffers from this bug on a ASUS P5E3 WS Pro (X38) motherboard).

I am not convinced I chacked 10 games and every time PCI-E changed to 2.0 even with a small load.
This is one of the smallest loads 30% of GPU use

pci-e change in P3-games do not use this mode

PCI-E change to 1.0 in P -state 12 idle mode


you do not loose performance in games, only i p3 mode--when you play movies and for this you do not need PCI-E 2.0

So show me furmark or any game with pci-e 1.0 on x38/x48/x58, I do not see, only idle and p3 state which in no way interferes of any performance .
