Hi guys,

I'm having audio/video desync issues when using a RedRocket card (a PCIe video hardware decoder). Mouse/window movement is jerky and audio drops out. It looks like a possible clock/HPET issue, as though I haven't set busratio in the boot plist (but I have!). In system profiler my 3930K still shows up as 3.2Ghz (although it's 4.4, 44x100), and it says the bus speed is 400Mhz. Is it worth injecting the right info into the config.plist? If so, what is the CPU type and what other info should I include?? I have busratio=44 but have also tried 32 with no luck. Any ideas?

Thanks!
 
Having the same issue - identical system as well!
 
I ended up replacing the motherboard with a Gigabyte X79-UP4. No issues with it.
