Can you over clock the new celeron D processor? I have the 2.93 340 celeron D can this be overclocked and what kind of speed can I get out of it safely?

To answer your question yes

Overclocking
Now let’s see how big the overclocking potential of the new Celeron D processors is. Theoretically, the 90nm Prescott core features greater frequency potential, which makes Celeron D processors better overclockable than the older Celerons. On the other hand, these CPUs are based on Prescott C0 core stepping, which is used only in Pentium 4 processors with 3.4GHz frequency. However, we have already managed to easily overclock these processors up to 3.6GHz with simple air cooling involved. Celeron D generates less heat than Pentium 4 that is why it can turn out even better overclockable than the Pentium 4.

We had two Celeron D processors on Prescott core in our lab with the nominal frequencies of 2.66GHz and 2.8GHz. To study the frequency potential of the new processor family we decided to overclock both of them. However, during our overclocking experiments it turned out that the standard cooler shipped with Celeron D is too weak to ensure sufficient cooling for our testing participants. During work both overclocked Celeron processors got overheated real quick, which resulted in system instability. Therefore, if you are planning to per4form some Celeron D overclocking make sure that you have a good cooler at hand. During our tests we used one of the best air cooling solutions from Zalman – CNPS7000A-Cu.

The second thing worth mentioning is the fact that the maximum frequency these processors managed to reach during our overclocking experiments is highly dependent on the power voltage. In other words, by increasing Vcore above the nominal, which is 1.375V in our case, the stability threshold for the CPU got higher. This Prescott’s behavior is a direct opposite to what Northwood core did, when the overclocking results hardly got any better with the processor Vcore growth. That is why to achieve better results we increased Vcore up to 1.475V for our testing participants. This 7% Vcore growth gives us some hope that the processor resource will not get too much smaller and it will not die earlier than expected. The first one to go through our tests appeared Celeron D 335 processor with 2.8GHz clock frequency. Keeping in mind that the FSB frequency of this CPU is 133MHz, the multiplier should equal 21x. When we overclocked this processor, we managed to increase the FSB frequency to 170MHz without losing any of the system stability.

Can you recommend an affordable cooling unit? And do you think 3.2ghz is out of the question or do you think it will be stable and if I do this will I fry my processor in the not to long future?

I think you could get to 3.2GHz BUT Not all processor are created equal. For example Barton 3000+ I overclocked from 2.16GHz to a 2.43GHz but the same exact processor that someone else has might only be able to be clocked to a 2.23 GHz (stable).

This all goes back to the manufacturing of the processors in the die (die being the sheet of silicon the processors created on). Now lets take the Athlon64 3400 in the beginning testing stages they will take a die and randomly select 10% of the processors from that die. If all 10% past the tests the whole die will go on to become a Athlon64 3400 BUT again not all processor on the die are created equal either some will clock higher then others some (very rarely are complete sh*t) Now if the 10% of that die fails the expectation of the 3400 and have a lower clock speed then what they where shooting for (the 3400) they will find out where they are most stable and sell them as...lets say Athlon64 3200.

So you are running at 2.93 GHz you say well to answer you question you may be able to get to 3.2 you may not then again you maybe able to go higher. Running at these increased speeds won't affect your processor physically unless your temps are in excess of 70 degrees C (That part is my opinion) some will say don't even co above 40 or 50 but I try not to go above 60.


AND finally cooling what do you want to do Air, Water, Phase Change, or maybe (Liquid Nitrogen hehe). Depends but Thermaltake with Artic Silver5 paste is pretty good.
 
Are operating systems a factor in over clocking a processor because I heard that Windows XP Pro can help over clock a processor a few notches i.e. 3.0 to 3.2GHz :confused:
 
I would like to go with air cooling! Is the artic paste you was talking about work with air cooling or is it a stand alone unit?

LOL where did you hear that? lol

Its never a standlone unit :)
