I have a athlon xp 2500+ that I've had for over a year and finally decide to try overclocking and seeing what it could do. I tried upping the FSB to 200mhz and lowering my multiplier to 10.5 and hit 3000+ easily with my Corsair XMS pc2700 (2x256) in dual channel. The setup ran stable, and with my Zalman cnps 7000 alcu, everything ran relatively cool at around 40C. Passed memtest, prime95, everything. Anyhow, I tried upping the multiplier up to 11 again to hit 3200+, but when I do, the computer posts just fine but the screen stays black when it should be showing the WindowsXP loading screen. It never actually loads windows and I have to reboot and change the multiplier back down to 10.5. I thought it might be my memory, and I wanted to upgrade to 1GB anyways, so I bought and installed some Geil pc3200 RAM (2x512). I did what I did before to hit 3000+ and again everything works fine, but I still get the same problem when I try for 3200+. Anyhow, long story short, my question is what do I need to do to successfully hit 3200+? Should I try increasing the CPU core voltage? if so, by how much? I'm not a hard core clocker, don't have a lot of experience at it. Mainly I just wanted improved performance at a value. Any info/advice? Thanks!
