Overclocking a Pentium D

I bought a pentium D (s775) with a stock speed of 2.66 GHz.
I don't know that much about overclocking processors, but I overclocked it to 2.90 GHz though.
I was just wondering, how much can a Pentium D take without having to switch to liquid cooling for further speeds?
I'm kind of at an intermediate level at building computers, although I already built mine with a good ASUS mobo.
 
I have clocked a few of the 805d and they vary from chip to chip but i would say at least 3.2 to 3.6ghz .

Try changing every possible stepping and make the best of your multiplier . I got these overclocks just using normal ram which was cheap and i saw i was having more luck with ram which didnt belong to corsair.

I got P 930D which goes to 4ghz easily , try and use a decent heat sink anf fan , preferably a freezer 7 pro , cheap and effective , this is another product which is cheap because of supply and demand.
 
Also use the 667 mhz ram rather . Because of supply and demand they are cheaper than other slower ones. You have a great multiplier on the P D so use it wisely and you will see speeds you have never seen also record your findings on a paper and when you have gone to far and it wont start then clear cmos and start again but the rush is so high that it cannot be matched so its worth every second.

Master it , you will love it :)
 
i actually dont think there's a cmos switch on my motherboard. My friend, whom is very intelligent with computers, couldn't find it. I know what it is too.
 
Look at your motherboard manual to see if there is a jumper, if not, then do the battery. Some boards have the auto-reset feature thingies though.

Anyway, different processors overclock differently. Some will go high before they require an increase in vcore, which puts more voltage into the chip and produces more heat. Others don't....sooo..

There aren't any thresholds in overclocking really (except for vcore, vdimm, and temps), you keep going till it gets too hot, you hit a wall, and/or the voltages get too high.
 
thanks for the advice.

and i just came to a blue screen every time i try to play a game on the 2.90 GHz setting, which doesnt make much sense aside from the possibility that it might be getting too hot?
I might turn it down later but what should i do to avoid that blue screen?

Get a solid aftermarket cooling solution. Intel's stock coolers are crap.
 
yea i have an 805 currently overclocked to 3.6 on the stock voltage. I am still messing around w/it but don't think it will go much higher than this on stock voltage. I have a zalman 7700 w/the fatality fan on it and it is running at 37 according to speedfan. But my room is hot as can be, prolly around 80-85 F bc i have no ac. At nite when it gets cooler it idles around 24-26. Loving these 805s. Just make sure you use good dividers and you should be fine.
 
I read somewhere that the 65nm Pentium D's (9xx) responds much better to even just a small raise i Vcore, compared to the 90nm 8xx's Pentium D's...

I got 3.9Ghz with 1 stick DDR2 533 PC2 4300 and a P5LD2 with a stock cooler at 1.4V. Just seat your heatsink right and you should be fine.
