Overclocking a P4 3.0 Ghz.

Whoa! Overclocking is an art, not an exact science. Two identical chips rarely react in the same way to overclocking. One chip might run fine at 3.4Ghz, while an identical one might fry at that speed. A lot depends on your mother board as well. All I know about Sandro's system is the board model. I haven't a clue as to the actual P4, other than it's a socket 775 chip. I'm assuming it's a Prescott (800Mhz FSB), but it could be a Cedar Mill. It makes a difference. :shock:Sentinel672002

If you think a Pentium 4 can choke at 3.4GHz, you're seriously underrating NetBurst. :lol: Pentium 4s can go stable upto 4.5GHz easily (if you have the right cooling and motherboard).

TC, I think your motherboard has a 915G chipset. Typically, Intel integrated graphics chipsets don't overclock AT ALL (no options in BIOS). Bad luck. Just double check, though.

Shot in the dark overclocking advise.

Alright, you've been in the BIOS. The front side bus speed, should be like 200Mhz (quad pumped=800Mhz total FSB). Since the multiplier on all the Intel P4s is locked, yours at 15 BTW (15x200=3000Mhz), you have to increase the frequency of the FSB to increase the chip speed. Baby steps and test, the only way to safely overclock any computer. Increase the 200Mhz rating in the BIOS by no more than 5Mhz to 205Mhz, save and exit the BIOS, then boot the system. Watch for any unusual behavior. Hangups, stutters, the BSOD, that sort of thing. If/when Windows is loaded, check the CPU temperature. If it is within normal range, run a few apps, or games. Optionally, an application like PCWizard can do this for you, by running benchmarking tests (it's free). Run the CPU bench a few times, then check the processor's temperature again. Overclocking is no good, if it overheats under load. If you determine, the system is cool and stable, reboot the system and increase the FSB another 5Mhz. I know it's time consuming, but it's safe. Eventually, by repeating this procedure, the system will become unstable, or overheat. When you reach this limit, restart your computer and back the FSB down to it's last stable frequency and that will be your magic number. If you were running an exotic cooling system of some kind, you might be able to push the CPU further, by over-volting it, but I'm not going to recommend it. The way of over-volting is the way of early CPU death IMO. 8)

I don't deny Prescott P4s can overclock. I just know how hot they can get when they are overclocked (surface of the sun springs to mind). And, since I don't know what kind of cooling system is hooked up to the CPU in question, I'm gonna er on the side of caution and what not. I was hoping the person asking about the overclock would provide more info.:|

Well 3.7 to 4GHz should be achievable, even on stock cooling.

But as I said, I doubt his motherboard can overclock.

I wish that was the case for the "Northwood" procs. Mine starts getting twitchy at about 150Mhz over stock. :(Sentinel672002

That's odd.

Do you think it's because of your motherboard?

Can I overclock my Pentium 4 3.2 GHz, if yes then up to what speed can I overclock it too?cero10

CPU model number?

Motherboard model?

I don't think it's the board. None of the P4C "Northwood" cores seemed to have much head room to OC. I dunno, maybe it's the twenty stage pipeline and the 800Mhz FSB. If I over-volt the proc, I can smooth it out a little, but heat becomes a problem (stock cooler). Here's the stats for my upgraded 2003 system;

Is it equiped with a stock heatsink and fan?Sentinel672002

No, it's got an Arctic Cooling Freezer 7.

I take it, you can't adjust the FSB frequency on that board, right? :(Sentinel672002

Apperantly not... I just tried again and it's all greyed out. :x
