Since downclocking the core fixes it, then I seriously doubt it's software related. I honestly think they've really just been pushing the cores of these things for too long because this problem has plagued me for years no matter what card I get, started like back in the 7800 days. I think they just clock them up to X core and test it just a bit and seems good then ship them, but after using it for some time you'll find it's not really 100% stable all the time at that core so you have to downclock it to use it.
