Paranoid, What kind of memory timings did you use? I had bad luck trying to over clock my winchester 3000+, but I am a newbie at that. I was using agressive 2-3-2-5 memory timings While I am no expert either, I seem to recall reading on Anand's that he uses 8 or 10 for the last parameter, with little or no performance penalty, and good increase in overclocking headroom. If you go way up, you may want to drop down to 2.5-3-3. Joe

@Paranoid - OC Which board do you use - chipset? There are mainly 2 crucial things. LDT speed and DRAM clock. First, when you increase your "FSB" (HT) Clock, then your LDT clock increases. Standard is a multi of 5, so, when you increase HT, the platform gets fast very instable. Try to use factor 4 or 3 (BIOS)!!! Which DRAM do you use? When increasing "FSB", you should setup SLOW!!! DRAM settings first, so you get a feeling, how fast the A64 could go. Use CL3!!! first! Second, try DRAM dividers like 133 or 166MHz, which reduce DRAM clock, when you increase HT. E.g. I went with 290MHz. Which DRAM could reach that with fast settings? Nearly impossible. So when I setup (Nforce4) a 166MHz setting (200 = standard), the DRAM goes down to 166/200290= 240,7Mhz from 290. That is also very fast, but the Samsungs (TCCC, better is TCCD) went fine. When your moduls are not as good, try 133, which lead to 133/200290= 193MHz. With these settings, you should easily reach higher clockspeeds . BTW - disable C&Q first. Many boards causes problems, when you overclock your system. This is not because the K8 has a failure, thats why many dividers will change. Thats more complicating and because the dividers will change, e.g. DRAM clock could reach a setting, on which it will not function correctly. So disable it first. BUGGI
