Athlon XP OC: Temp stable, but system hangs?

[clicknext]

Hi, I have an Athlon XP 2000+ and Gigabyte G7VAXP motherboard. I'm using stock AMD cooling.

I overclocked the FSB to 144, effectively making it an XP 2200+, at 1.8Ghz. The temperature is always around 50 celcius, but the system hangs right after the boot screen, before windows asks for my password. What could be happening?

Thanks

The problem could be several things, or more than one of several things. Before looking at anything else, I think the main problem you will have overclocking that chip is your stock HSF. Raising the vcore could do the trick, but that introduces heat which brings the need for good cooling.
Having said that, I think here is a good place to find the answers you need.

Another problem could be your memory...

Oooohh, overclocking FSB increases ram clock too? I thought ram would stay the same since I already have DDR333 set in the bios. I'll try setting it to DDR266?

Ok, I don't think it's the ram. I have DDR333 but with 133 FSB, I can set it to DDR400 no prob. Once I up the FSB to 144 or above, it dies.

Actually, I just tried some more now, and it seems to be unstable at 140 FSB too. What's wrong? Could it be that my AGP/PCI can't take it? What's the usual highest stable temp for a palamino? Would it be normal that my CPU can only be overclocked by that much?

hmm, you should use a program call mbm 5 to check your CPU's temperature (not overclocked) at idle and see how much it'll go up at full load (100%).,. Also set you Ram timming to cl3 and the slowest setting. Slowly increase the FSB 2 at a time.. If you have no problem pass 140 then then it's your ram that's causing the BSOF. But if you still have the same problems after lowering you ram timming then it's something else,, like Not enough cooling,, not enough power for your CPU, Hard drive can that the increase MHz, ETC..

It can also be just that your CPU is already at it's max..

The normal unlocked overclock I get and it seems to me everybody else is between 140-147 FBS. Most AMD CPUs won?t go higher unless you unlock and lower multiple. And it is not uncommon to have a 1 Mhz boost be 100% stable or just a no boot won?t start nightmare. 2000+ is already near max for its core. hence the switch by AMD to the new revison B core.
