Clocking Pentium 4 CPU w/XP Pro

[nickel052]

I've been using my old VIA P4M266-8233 for the past 6 years. The computer itself is 9 years old but I stick to old stuff for what I use it for. The computer had a Pentium 4 1.8GHz processor in it for the longest time. I swapped it out for a Pentium 4 2.40GHz that a friend gave to me from his old computer. I installed it, booted and worked fine. But it wasn't clocking at the full 2.4. It was still clocking at the old 1.8. I did some research online on how to overclock a processor. I went into bios and noticed that there are only 2 changeable settings; CPU voltage and speed. The default voltage is 1.525V and the default speed was clocking at 100x18.0 (1.80GHz). Based on what I read online, for the default speed, the only required voltage was between 1.250V and 1.450V. So I decided to bump up ONLY the CPU speed. I cannot bump passed 102x18.0 (1.84GHz) and 1.525V without boot failure. Sometimes the computer turns on and does nothing, at other times it boots and restarts and other times it boots and freezes shortly after boot. I have tried lowering and raising the voltage. The CPU temperatures were between 49 and 55 celcius. At which these high temperatures were AFTER I raised the voltage. It got so hot that my boot screen was being displayed choppy and was obviously too hot. Why am I not able to push past 1.84GHz on a 2.40Ghz P4 processor? Is it because the computer is just too old? The system BIOS is dated July of 2002. I do have 3 PCI components installed. A wireless device, USB 2.0 card, and a modem. The onboard graphics adapter has given me a heck of problems in the past. The computer has 1 GB of ram installed. I was also told that it could be possible that the components installed may not be capable of overclocking, but I am confused since I have actually yet to overclock the capable speed of the processor. I do have some ideas on how to repair but I would be trying new ideas all day. I thinking of removing the stand-alone components. I was wondering if anyone else had any more ideas to solve this crap, maybe someone who has had more experience with this then I have had or maybe knows what the best repair idea is.

Any help I can get is great. If not 1.84 is still better than 1.80.

Your question may be more suited in the hardware forum, you'll find the hardware experts in that forum.

Thanks I searched for a "pentium" forum before but thats what I was looking for.

First of all, you need to identify the mainboard, stating the CHIPSET is just not enough...

basically, what I mean is that you probably need a BIOS update for the mainboard to recognize the newer CPU correctly...

once that is done, YOU SHOULD NOT need to OC the CPU at all...

Just like BadBigBen said, you need to identify the manufacturer and model of the board. Then go to the manufacturer's web site. They will generally have lists of all the CPUs compatible with that particular board. Also, another thing you should check is whether that is a 400Mhz FSB or 533Mhz FSB Pentium 4. It should list that on the outside of the processor. If it is 533Mhz, check to see if there is a jumper on the motherboard that can be switch the FSB to 533Mhz. That should bump the processor clock up to 2.4Ghz.

This is a duplicate post in general, the cpu has been determined as a 533 fsb, the system board does not have a clock jumper, but there is a newer bios that may unlock the speed.
