I have a K8N Neo4, A64 3200+ 939pin 90nm CPU and PQI Turbo PC4000 memory. Started by going for the gusto at 260 Mhz FSB, 4X HTT and various voltages. Prime95 always failed. Lowered to 250 Mhz FSB, 4x HTT and 8x multiplier at stock voltages that way CPU & Memory are at rated speeds. Still crashes in Prime95. I'm using stock HSF but I don't see a problem with that since the most I've seen the temp rise is to 50c. Any Suggestions?
