Safely, 3.5-3.7Ghz is the upper limit for 24/7 operation, though you could probably hit 4ghz with everything just perfect (120mm 5000rpm+ fan, Heatpipe/Copper cooler, AS5, perhaps some lapping, perfect mobo/ram/timing).

So many variables to look at .. what mobo/ram/psu/cooler/case/ambient room temps?

really? huh, didn't a lot of the 805's hit 4ghz? i figured the 920 would go higher, or at least as high as the 805.

A lot of the 805s hit 4Ghz, but the power draw and heat output is enormous. Much greater than anything I would be willing to run on an everyday basis.

I had an 805 overclocked to 3.52Ghz with a minor voltage increase. Had a modified Big Typhoon cooler on it. Temps were pretty good, with full load barely breaking 60C. I ran it overclocked like that for four months. One day, my pc started hard rebooting. I had no clue why. It continued using it, but the reboots began happening more and more frequently. I decided to take the entire pc apart and put it back together to see if anything came loose or something. I found the problem. The 4 pin power connector for the motherboard and the end on the powersupply was burnt to a crisp. Both the male and female connectors were black and flaky. Apparently, the motherboard could not handle such a large power draw for such a long period of time. Mainboard was an Abit IL8. Powersupply was a Fortron Bluestorm 500W.

Not much of an OC really but go for it if you feel comfortable @ 3GHz.

Question, should I get a watercooling kit and push it to 4ghz? If so, whats a good water kit to buy?

Why not use the water kit money and by a Core 2 Duo, then sell the Pentium D and buy a Tuniq Tower 120?

It would be a LOT!!! more worthwhile.

any, lol. wait for the july 22 price drops. basically just pick a price, they'll all overclock well and put your pent d, even at 4ghz, to shame.

If this is your target for a Pentium D then buy the E6850 which is stock 3GHz and would be WAY!!! faster for ~$266.

Well if you don't have the Pentium D already, you might want to go for a cheap Core 2 Duo instead.
