Operation Time


Above you see the Arctic Silver smoothly applied and the processor seated in its socket.


Instead of using the default, lower CFM fan that came with the stock heatsink, I installed a high CFM Delta 60mm fan on the heatsink instead. The stock Pentium 4 heatsink (that shipped with the system) is actually really good and has a large copper base so I figured Iíd pair up a good heatsink with an equally good fan. Youíll notice that the fan is pulling air away from the heatsink and there is tape around the top half of the heatsink. This method is the forced-air method Iíve been talking about in some of my other articles and reviews.

I also placed some Arctic Silver between the north bridge and the heatsink that sits atop. This should keep things cool as the northbridge is practically a Pentium 3 flip chip and runs quite hot.

Remember, those pictures do not reflect the Asus P4T motherboard I used to overclock the processor.

Overclocking

Hereís where the fun begins. The Intel D850GB doesnít have settings for FSB nor does it have settings for multiplier settings. Thus, we resort to using an enthusiast targeted board like the Asus P4T. You can adjust both FSB and multiplier speeds from inside the P4Tís Advanced BIOS settings.

After a while of trial run of testing different FSB and multiplier settings, I managed to settle on a stable overclock of 2.04GHz (117MHz FSB * 17.5X multiplier). For a processor with deep pipelines like the Pentium 4, an overclock of over 300MHz isnít spectacular, but reaching 2GHz is definitely something to see. Before processors broke the 1GHz barrier a while back, reaching 1GHz took a very, very long time. In light of this, Intel will have an official 2GHz processor sometime in the autumn.

As processor speeds rise higher and higher, fabricating multi-gigahertz processors becomes easier. What I mean by easier is that speeds are reached much easier. Actually fabricating the processor however, is another issue. Intel and AMD will have to research better methods to manufacture processors if they want to continue pushing the envelope.

All in all, the Pentium 4 overclocks quite nicely no matter what speed grade you have. Letís see how it performs.
