So far, everybody has had a problem with doing "make world" after some period of time. To get AMD to pay attention, they need to see that it's a problem that's _not_ tied to any specific action in the make world itself, but something within the chip or it's operating environment. If it is a heat related problem with boards that are supposed to be approved for use with the K6, well, we may get the "It works fine under NT & 95..." argument. Ie, the average user doesn't impose the same load on their cpu that we're talking about. Sigh. I really like using the K5 chips in my servers & was looking forward to the performance of the K6. If it can't run load under 7x24 conditions, then it's _not_ an option for me. Anybody know how the Cyrix chips hold up under heavy server usage conditions?
