Logos 0 Posted February 6, 2006 Share Posted February 6, 2006 The title speaks for itself. How do I OC' my P4 3.0 HT CPU ← If you have an Intel motherboard, you probably don't because they probably won't have a BIOS setting for it. If you have a motherboard by most other mobo manafacturers, there will be an option in your BIOS to increase you Front Side Bus. Basically, for an Intel proc, your processing speed is your Frontside Bus Speed multiplied by some number (aptly named: the multiplier) fixed in your processor. Your specific processor, Snake, assuming it's a P4 Northwood, has a multiplier of 15, multiplied by the 200MHz of your frontside bus = 3000 MHz, or 3 GHz. If you raise your FSB to 225MHz, your processor will be running at 3.375 MHz. If you raise the FSB to 250MHz, your proc will be running at 3.75GHz, etc., etc.. Now, you probably shouldn't attempt this without doing a fair amount of research on it first to familiarize yourself with WHAT you're actually doing, what the potential payoffs are, and what the risks are. For example, in your case, your proc might handle a bump to 220MHz, but it wouldn't even boot at 250MHz without specialized cooling, and then only maybe. Your ceiling is also going to be limited by the type of memory you have, and where your memory divider is set. You also don't have as much room to move up with a high-end proc within a given core, which you have, so there's really not even that much room for you to improve. Basically, I don't recommend you undertake this until you've studied up on it. Type "how to overclock" into Google and read away. There's more to know than just what setting to change. BTW, it voids your warranty. --Logos Quote Link to post Share on other sites
Snake@War 0 Posted February 6, 2006 Author Share Posted February 6, 2006 I've OC'd my GPU before, and I know OCing voids the warranty. I've had the computer for 2.5 yrs so far so I'm not worried about the warranty. How would I know if it was a Northwood? My mobo is an ITE, I believe. Not sure of the model number seeing I'm at work right now. I know the risks, and my memory is 1.28GB PC2700. Is that a bottleneck for my system? I have stock cooling in my system, but I'm going to get some water soon. Quote Link to post Share on other sites
Snake@War 0 Posted February 6, 2006 Author Share Posted February 6, 2006 The max, I just found out, for my CPU model is 3.4GHZ. I can skip out on 400MHZ. Quote Link to post Share on other sites
CR6 0 Posted February 7, 2006 Share Posted February 7, 2006 Why do you want to overclock a 3 GHz HT CPU? It's good enough for most apps and games these days. You do likely have a Northwood if your system is >2 yrs old. The best overclocking CPUs in that generation were 2.4GHz o/c'd to 3GHz or 3.2GHz, so you won't get much boost with a 3GHz. You also need to find out if your front side bus is 800MHz or 533MHz. If it's 800MHz FSB, you are getting sub par performance with PC2700 memory. Also, the amount of RAM you have 1.28GB sounds funny for a system that should be running dual channel. Do you have 2x1GB and 2x 128MB sticks? I had a friend running his P4 with a single stick of PC3200 (DDR400) RAM and didn't realize his mobo could do dual channel. He got a big boost in performance just buying a second equal stick of RAM and running his FSB at 800MHz. You definitely need to do more research about not just your CPU, but your RAM if you want to o/c. Quote Link to post Share on other sites
Snake@War 0 Posted February 7, 2006 Author Share Posted February 7, 2006 I have 2x512mb+1x256mb. And yes, it IS PC2700. I'll double check on the FSB speed, though. Quote Link to post Share on other sites
Papa6 88 Posted February 7, 2006 Share Posted February 7, 2006 Does this mean OC'ing a dualcore is now a mute subject? I think so as the frontside bus is no more. the processors are now at core speed within the silicon right? Quote Link to post Share on other sites

Logos 0 Posted February 8, 2006 Share Posted February 8, 2006 (edited) Or the chip fries. ← Isn't that the point, WK? Fry your chip -- time to upgrade. Whoo hoo! Seriously, with modern chips, if you don't jack up your vcore, it's unlikely that you'll get your chip hot enough to fry it. The system is more likely to become unstable and crash before getting that hot. With Intel, they used to, and I suspect still do (though I don't know for sure -- I haven't kept close track of Intel procs for a couple of years) have a feature in their procs that will throttle the proc down if it gets too hot. With AMD procs, which don't get anywhere near as hot as Intel Procs, your proc is simply going to crash your system before you get it running fast enough to produce enough heat to damage it. THAT SAID, I do not recommend casual OCing, or OCing to try to stretch procs/systems as software advances enough to start putting a beating on it. In this case, you probably don't have the hardware to accomplish it in a way that is wothwhile; thus, the end is probably too near anyway. Where I woud recommend OCing is with someone who A - wants to build a high-end system at a low-end cost. This is the real benefit. For example, my 1.8GHz Athlon64 (Winchester core) cost me about $180, but I OCed it to 2.7GHz at a time that a 2.7GHz Athlon64 did not exist, and the closest A64 to that speed was $800-$900. and B - the person is willing to spend the time to really know what they're doing, REALLY REALLY understand what hardware to buy, and buy it all at the time that the system is built. --Logos Edited February 8, 2006 by Logos Quote Link to post Share on other sites

I just built a P4 630 (3GHz) and it's very quiet doing 2D. Perhaps the technology you are referring is the earlier tech that would shut off a P4 off when overheating. With AMD procs, which don't get anywhere near as hot as Intel Procs ← This is only true in the last 1-2 years, esp after the Athlon 64 and Prescott P4's came out. Over 2 years ago, the Northwood P4's generally ran cooler and quieter than the equivalent Athlon XPs. B - the person is willing to spend the time to really know what they're doing, REALLY REALLY understand what hardware to buy, and buy it all at the time that the system is built. ← Exactly. If you're really serious about OC'ing, you should be going elsewhere for info than just these forums. Although ppl here are very knowledgeable, overclocking is risky, and requires lots of research about your parts. Unless you got lots of $$ to blow on new parts Back in the day, you could o/c a Celeron 300MHz to 450MHz without much probs. The 50% increase was well worth it. I currently have a P4 2.4 Northwood that easily o/c's to 3GHz (25% increase). The improved bandwidth on the FSB is nice too. OC'ing a 3GHz to 3.2-3.4 GHz (10-15% increase) may not be worth the risk/wear and tear on your parts, but it's up to you. @Snake@war: If you want to improve your current system's performance without risk, you should focus on your memory subsystem. Tell us exactly what mobo you have, and we can see what FSB it supports and if it runs dual channel. You may actually be hurting your performance by having the single 256MB stick in there.

Volcano 12 maybe? I'm not sure. Anyway, it sounds a lot like hair-dryer is running inside my case. BTW, for Athlon64's on DFI Lanparty NForce 4 Ultra and SLI mobos, overclocks of 50% are not unheard of, even with stock HSF. It's the mobo.

ITE is a company that designs components such as I/O chips that would go on the motherboard, but does not itself manufacture motherboards. Someone else recently posted about a good utility that can identify your mobo: http://www.cpuid.org/cpuz.php Download it and run the CPUZ.exe, and in the dialog click the mainboard tab, and tell us the motherboard's 1) Manufacturer 2) Model and revision 3) Chipset Quote Link to post Share on other sites

You have a P4 that can support up to 800MHz FSB (200MHz quad-pumped) However, your SiS-648FX motherboard only has single-channel memory support, so the max FSB you can run on your motherboard is 400MHz http://www.digit-life.com/articles2/roundu...0-chipsets.html Even though your motherboard is on the lower-end (i.e. not dual-channel), you are not taking advantage of the full potential of it as your memory is running at 333MHz (PC2700) Your best stick of RAM is the 256MB one, since it is 400MHz (PC3200) so I would leave it in. However, when used with your PC2700 RAM, it will only run at 333MHz. So in summary, you've got a good CPU, but a lower-end motherboard and most of your RAM does not take full advantage of it.
