Even though performance of contemporary personal computers does not heavily depend on clock-speeds of central processing units, it is still interesting to know the maximum clock-speed that can be achieved by modern microprocessors. Recently a new frequency record was set, when overclockers from XtremeLabs.org pushed Intel Celeron D 347 to nearly 8.20GHz.
Intel Celeron D 347 processor, which is based on the renowned NetBurst micro-architecture, is made using 65nm process technology and officially works at 3.06GHz. However, with the help of modified DFI LanParty UT P35 (Intel P35, revision A2), OCZ Technology memory and a lot of liquid nitrogen overclocker TiN from Xtremelabs.org reached 8199.5MHz clock-speed on the central processing unit.
To date, 8199.5MHz is the highest clock-speed ever reached by overclockers that has been validated by CPU-Z database.
Unfortunately, the overclockers did not run a set of benchmarks to find out actual performance of the extremely overclocked Celeron D 347. As a result, it is not known whether the chip at 8.20GHz can actually outperform modern Intel Core i7 microprocessors at around 3.00GHz.

Exciting! 8.2ghz!
yet... strangely disappointing...
So this is almost 3x stock clock. Even if Netburst performance did directly correlate with clock speed, sadly 3x it's original performance pbly wouldn't beat a QC h/t Ci7...

Unless you are using early 2Ks soft/benches. The i7 does not shine in a single threaded environment.

This was done on the oh so out of date and less IPC Netburst Architecture. This isnt news, this is crap. Everyone knows the NB arch gets really high clocks under sub zero temps because they are massively high leakage chips that produce a crap load of heat. It has been shown over and over again that high leakage chips do better under sub zero temps than the lower leakage chips. The AMD PII TWKR chips were all high leakage chips cherry picked for people to use under the likes of LN2 or LHe. Air or Water so severely limits these chips since they produce a ton of heat cause they are inefficient till they get cold.
I highly doubt they could have even come close to running bench marks on this chip, it was probably barely stable enough to get a cpuz validation. It was a suicide run on an old crappy cut down chip that leaks like a sieve.

Good pint Daseto. I also have my doubts most likely they couldn't run benchmarks because of stability issues. Possibility remains, waiting to see the benchmarks ;-D.

Yeah, I agree with everything said above. The clock speed itself is impressive. With what it was achieved is not. I can, however, imagine the excitement of seeing 8.2 GHz during boot-up.

Whats to be applauded is the effort of achieving such a high OC
It has nothing to do with the CPU used

well i have an amazing thing to post here i think i have overclocked my athlon 2 620 processor to 8.55 ghz with onley the h50 water cooler unit by corsair did not suckseed in 3dmark 05 crashed as it was finishing the final run did 2 sucksessfull runs crashed on third and final so it was stable for about 20 mins give or take but just got dun was able to get a screen shot and here it is
http://i707.photobucket.c...smitty2323/Untitled-3.png i did under clock it after crashing back to 2.8 ghz at its origanal clock speed this is a quad core processor i think amd is the best when it comes to this but was not stable after 2 3dmark o5 runs

bad news for my post the processor is dead will not boot or nothing i think its fried i will buy another one and find out one of the best and worst days of my life (<.>*<.>
