Help with overclocking.

[de8212]

I decided to overclock my XP1600 just to see what it could do. I saw on another site someone set there's to 10.5 * 150 (1575MHz). After I booted it I decided to reboot it a couple of times to see if everything was OK. The first boot, it froze at the WinXP login screen. Rebooted agian and messed around in windows for about 5 -20 minutes, no problems.
Loaded up Call of Duty and played for~5 minutes and then the screen froze and looked all washed out (lighter colored) and the sound started skipping in a loop (like a scratched record).
I had to do a hard reboot and I noticed the BIOS temp only showed 41 deg. C so I don't think it was a temp related problem.
Anything else I could try to get it running at that speed?

BTW, this is on an epox 8kha+, w/1GB crucial pc2100 DDR RAM (all on turbo settings). ANd I had upped the voltage from 1.75 to 1.85.
ALso the video card, older gf3 ti200 has been overclocked to somewhere around 230/500 for a week or two now with no problems.
any ideas?

Overclocking is part science, part art and part luck. No two machines will overclock the same. If you have upped voltages and have adequate cooling, it is just a matter of experimenting until you have a stable system. When your machine becomes unstable, you back off settings little by little until it finally works properly.

It is frustrating when you see that some people get their machines running much faster without a problem but it is just luck of the hardware draw. Some machines will never overclock that well no matter what you do.

OK, so if I want to try again at a lower setting, would I change the 10.5# lower or the 150# lower?
IOW, 11*142 = 1562 which is lower but 10*155 = 1550?
Which # should I adjust, the multipler or the fsb?

When you increase the fsb, you are putting stress on the rest of your system. When things start to fail, you can't really be sure what the cause was. I would leave the fsb in spec and just play with the multiplier first. I wouldn't want to run the fsb under spec. So, once you have the processor running well, then try increasing fsb in small increments.

Another good thing to do is to run benchmarks along the way and see what gives you the best results. You might find that upping only the fsb and leaving the multiplier alone gives you better performance than the other way around.
