I have my e6300 on a Gigabyte S3 clocked to 3.2ghz. I can run Orthos for hours with all three settings (large/small/mix) with no issues. I can run TAT for hours with no crashes. I can play Unreal for hours without my Nostromo (game controller) plugged in.

However, once I plug it in, Unreal will crash within 10 minutes. Frozen with the last sound repeating like an IRQ crash.

If I bring the overclock down to 3ghz, I am stable throughout Unreal with the Nos plugged in.

Now, logic would say maybe plugging in this USB device pushes my PSU to the edge but I have a 630watt PSU and am nowhere near putting a strain on it. I've calculated that even at full draw the MOST I could pull is 480watts.

Perhaps there is something I am missing as I am no overclocking expert but is there any chance a USB device would be affected by the FSB speed?
