Not sure if I am posting this query in right place...my apologies if it should be elsewhere.
I use my system primarily for flight sim with X-Plane9.
After overclocking my i7 920 to 4GHz I began having some problems with X-Plane.
First problem: system fails to recognize some of the hardware modules used in XP9. Specifically, it fails to recognize the radio module (GoFlight GF166). Unplugging the module from the USB hub & plugging it back in sometimes corrects the problem but not consistently.
Second problem: having rendering problems in XP9. Specifically, have light & dark bands moving rapidly across the ground...looks like cloud shadows but moving very quickly. Seems this was rain. Tried settings for clear skies & looked ok. Tried again with rain, ground shadow problem was not as bad, but no apparent rain & no rain on windscreen.
Sandy Barbour (X-Plane guy...x-plane.org forum if interested) said it might be a bus problem.
Any help will be greatly appreciated.
