Most people are probably aware of the PCIe x1 bug on a few mobos out there (currently the P35 lineup from Gigabyte seems to have the most problems). As a DS4 owner, I'm one of the suffering users. No matter what I have tried, I cannot set my FSB above 410MHz without loosing my x16 PCIe speed.

The interesting this is, along the way, I've noticed more irregularities when the speed drops. For one, onboard audio playback is very choppy whever doing anything else (for instance, scrolling a webpage or opening another program).

The new one I just noticed is very strange temprature fluctuations on the CPU:



Can anyone explain this? Has anyone else seen this occur?

I think that the PCIe speed drop is one of many symptoms signaling a problem of greater scale. Maybe that's obvious to some, but it being labled as a PCIe x1 bug is misleading to me...that does not seem to be the cause, just an effect.
