Thanks for getting back to me. To a certain extent I agree with you concerning that it is probably not much of a problem for non Linux users, but I have read of people having issues rendering in Blender and some programing stuff in Windows. Apparently it all depends on how stressed you CPU is and how well made. Mine, even though it was produced after the 25th week, would SEGFAULT within 90sec and couldn't get past 11 loops. This would seem to indicate that the issue was not in fact corrected after week 25. In either case I do plan to do rendering and didn't want to take a chance of having issues so I did an RMA. In the end I may regret that, but we will see. I have been an AMD guy since 90's, but I have to admit I am a little discouraged about how this has been handled. I think it would have been helpful if AMD had come out with some official statement and guidelines. Thanks again.
