Odd behavior of CPU

[rearden888]

Well, I'm having an interesting problem. I have P3V4X MBD and a PIII 933 Cu CPU. I am attempting to reload Win2K on my system, which you can see the full readout of at my rigs page. However, whenever I set the BIOS to use the CPU as a 933, I get a bad video beep code and a CPU overheat beep code. I'm actually not sure what the second is, because I can find no description of it in the BIOS docs and I have never heard it before. It's a high pitch and then a long low pitch beep, it doesn't sound good. In any case ,when I set the MBD back down to use the CPU as a 466, it works fine. Has anyone encountered a problem like this before? I have another CPU and will try swapping them out and seeing if I have the same problem. Otherwise, I will just try and have the CPU replaced. Oh, the CPU is a retail model, by the way.

Thank you for any help.

Have you tried updating to the latest BIOS?

If you haven't already done so, you need to visit the Asus site
for info on running the P3v4x faster than 800 or so.

Hope this helps.

Ok, I tried something that was suggested in the Asus article. I tried manual controls on the BIOS. Setting it at the manual settings for 933 didn't work, that is, setting the FSB frequency to 133 mhz gave me the same result as setting it on the regular settings for 933, no video beep code and then that one that I don't know it's meaning. However, when I set the frequency down to 130 mhz FSB, so the CPU was running at 910 mhz, it works fine, and I've been running it that way for a couple of hours now. Does anyone know what might have caused this behavior? Would this be the result of a bad CPU yield? I ran it on the 933 regular setting for over a year now. Thanks again
