Over the past year I have built a machine with a 800MHZ athlon slot A and a Abit ka7, and two machines with 900MHZ athlon slot A and Abit ka7-100 for some other people. My buddy built an 800MHZ Athlon slot A with KA7-100 and I have two macjines at my house wityh same mobo/chip combo. The first three machines above have all had problems to where I had to replace chip and mobo....Anyone else seen this phenomenon?
