.. on an ASUS K8N-E Deluxe, Athlon 64 3400+, 1gb PC3200 RAM. My system regularly freezes with fastwrites enables, but works fine if I disable it. So I have a few (well, four) questions: 1) Why is this hapenning? What is it about fastwrites which causes my system to crash? 2) Could I regard one or other bits of my hardware to be "faulty"? 3) Is there any software yet available which will enable me to use fastwrites and have a stable system? 4) Is this a common problem?
