P3 - 700 O/C

[By_The_Lake]

I just bought a P3-700 and want to get the most MHz for the least. So I was wondering what is considered the most reliable way to O/C. Is it better to take the CPU up slowly (at least until it fails to post at recommended voltage) or is it OK to go for the gusto right away? What method(s) do you guys recommend?

The recommend way is to start out slow and carefully work your way up. If this is your first major attempt at overclocking, you must do this because you'll find that tweaking and cooling mods will be needed as you go.

When I first started overclocking, I was thrilled to make any small little progress, but now, people seem to "expect" to get huge gains immediately. I've had people email asking how to get as much out of their system as I have mine.

How do I explain the 100's of hours that I've spent researching, reading articles, trying different cooling mods, tweaking, testing, asking questions, checking temps, benchmarking, etc., etc.?

Another note to add is that some on the forum will suggest that you burn in the chip. This would be running it at the 700 speed but with a higher voltage (with adequate cooling). There are several programs you can use to help burn in a chip including Sandra.

Marty, I hadn't read anything from you in a while, but was hoping you were still around. Adding to your CPU "burn in" comment, I really think that there is something to getting a chip "broken in" not unlike a brand new car engine. I've always had much better luck overclocking used CPUs than new ones. The burn in is probably just a way to break it in faster. This P-III 700 chip for example, the more I use it, the more I seem to be able to overclock it.

To save time I and because it is unlikely it wouldn't work I would recomend going straight to 933 (7x133) at default voltage, if it posts and is unstable, doesn't get into windows or just won't post keep adding 0.05v until it is, but stay under 1.9v with the default intel cooler and under 2v with a good cooler (you are probabally ok up to 2v but I wouldn't recomend it) if you can't get 933mhz stable with the default intel cooled then either a good Global Win or Alpha cooler should help, Alpha's are better quality but they both perform about the same and the global wins are cheaper.

Thanks for your advice guys. I installed the CPU last night and have stepped up the FSB 3x - 100, 105, 110, 115. I will leave it running @ 805MHz - 1.7 v for now. So far so good. What temp is considered reasonable for the P3-700?

I added my other system components to the comments area so you will have a better idea what we are dealing with here. In case this doesn't show when I post I have added the main parts below.

Globalwin FOP-32

For overclocking, I would try to keep the temps under 37c...and it should be stable.
The cBO stepping will top out around 950 or so, and the cCO, well I have had mine to 1125mhz...your results may vary.
BTW, have you overclocked your video card yet?
I have the same card, and have had good luck with that (with the right drivers)of course
I forgot to say Welcome to the forum

try go to 125 fsb... my ca2 got there super stable... which was max for ca2 about.... cb0 should do that easy, and cc0 even easier....

thats 700@875

By-the-Lake, I think your mobo is pretty nice one.. All the components will make the difference in achieving good overclocking. You have very nice RAM and HSF.. Find out what stepping type of CPU you have if you can. To answer your question, whether you have a cB0 or cC0 stepping, I would try 933mhz straight out of the box. 933mhz is reliable way of overclocking on the P3 700s. and dont worry you won't hurt your CPU. It's not easy to damage them unless you increase the voltages all the way up.
Good luck overclocking. :)

Thanks. Actually I did find out the stepping - it is cC0. I found this info on an Intel website that was mentioned in someone elses post description (http://support.intel.com/support/processors/sspec/p3p.htm). My CPU is SL4CH. I am a little bit worried about further O/C because my temp is a little high - MBM5 49C/32C, but that is likely due to the amount of thermal paste I used (I recycled). I will buy some thermal paste later today and check the temp again. If it drops to 30 something then I will continue to O/C and order some AS later.

. oh...ok yeah.. that temp you reported surely is high. yeah.. the Artic Silver would be great. sounds like good plan!

[By_The_Lake]

Looks like I might have a winner - my quest for 1GHz is getting closer! I bought some thermal paste and made the coverage a little thicker, but the temp is still high after bosting the FSB to 133. Temp is 49/29 with load. The CPU seems very stable though. Could it be a temp malfunction - as noted on the Asus CUSL2? I am using MBM5 for the temp readings. Any idea how much difference Artic Silver would make over regular thermal paste?
