graphics card pci-e 1x bottleneck???
hi, I've just tried o/c my Point of View 8800GTS graphics card, which went fine. With Riva Tuner 2.01, I managed to push the card from 513/792mhz to 560/900mhz. I also had to change the BIOS PCI-E to 110mhz so that the card's gpu didn't switch over to 1x.
This was okay up till the point of today, when i realised the graphics card gpu had switched back to 1x. The pc was very slow in loading and doing anything else is slow too.
My initial reaction was to change back to default of 513/792mhz, but this hasn't solved the problem. I even tried adjusting the bios setting between 100mhz and 110mhz, but it seems to be that for a while it will work at 16x, but then revert back to 1x
What could be wrong here?
