As show the results of experiences, obtained in our laboratory, the high coefficient of processor core 2 Duo e4300 (1.8 GHz) far from always guarantees maximum overclock. Certainly, to obtain frequency on the order of 3.2 GHz for the processor with default frequency 1.8 GHz is sufficiently good, but to the most extreme overclockers in this case do not give higher results, obtained with the use of processors series core 2 Duo e6xxx.
In the end of April Intel will not only lower prices of processors conroe, but also will present processor core 2 Duo e4400 (2.0 GHz) with 800 MHz system bus and 2 mb cache in the second level. Its wholesale price in the anoncement moment will be equal to $133, and many overclock amateurs will for sure prefer to pay the additional $20 in order to get it instead of Core 2 Duo e4300 (1.8 GHz) to obtain processor with higher coefficient 10x :-). who know how high can clock this CPU the reserve 1 x multiplier can be useful in some extreme overclock case :-).
We are already familiar with the results of overclock for one engineering model core 2 Duo e4400 (2.0 GHz) : with the use of air cooling it overclock to 3.5 GHz. In the hands of the well-known Shanghai overclockers (Victor wang) fell other processor core 2 Duo e4400 (2.0 GHz), and it shared its overclocking impressions in forum xtremeSystems.org.
Overclock was on the modified motherboard asus p5B-Deluxe wiFi/AP, which allow to raise the vcore ( cpu core voltage ) on core of processor to 1.66 v. so to cool the processor with such vcore was used a water cooling system. Victor wang was able to take a screen shot at the frequency 3720 MHz, but here the test super PI 1M was executed only at the frequencies not more than 3671 MHz.
Passage for the cryogenic cooling (type was not defined), which allow to reduce temperature to - 30 degrees , allowed it ti overclock processor to 4069 MHz, screen shot was possible at the frequency 4080 MHz.
Let us note that the obtained results are not record for core allendale-L2 , since at the beginning of February at the pages of forum xtremeSystems already appeared the references about the overclock of processor core 2 Duo e4300 (1.8 GHz) to the frequencies 4.5-4.6 GHz on different motherboards with the use of single-stage cooling. This corresponds to a increase of frequency by 2,5 times or by 150%! . we can not take those result as absolute reference because : First, processor must be successful in the plan of its overclocking potential. Secondly, Freon, dry ice and liquid nitrogen use only some overclocker, and the frequency of 4.0 GHz to the representatives of family core 2 Duo e4xxx are rarely submitted on air or water.
