I don't think WCG can trigger this bug. I've been running Phenom 9600 at stock on WCG for 4 days non stop - not a single crash. I beleive there are few more ppl that run WCG or any other F@H app on Phenom even on higher clock speeds. this is just not that kind of load. Though if you running something elsevery CPU intensive...don't know. This guy at x86-64...there is no explanation of what exactly he was doing to get this error
