The processors of Intel with the core of microphone-architecture use already the bus of system 333 (1333) megahertz. The balances of the new frequency of bus of system is completely military career and the overclocker already reached frequencies 400 (1600) and 500 (2000) megahertz FSB. The minimum multiplier of the EC of new processors remain as a x7 preceding, C. - with-D., thus with the overclock the new bottom-of-the-range duet e6550 of core 2 of processors of Intel will not be a little a e6300 or simpler E6320 only preceding.
For those which usually the overclock their processor, there is not significant advantages of passage with FSB 333 megahertz of 266 megahertz, the test showed that at the frequency the execution between the processor two equalizes (266 megahertz) and (333Mhz) is in the best business 1-2%. The only positive side with the new processor of 333 megahertz are: increase in the specific execution, more an high frequency of processors with the volume of hiding-place of 4 mbs on the second level and finally ALL this is proposed on the preceding prices.
Also let us note that the new consumption of energy of processors in at-rest state was reduced to 8 W: it apparent in comparison of 12 W with revisions preceding of core (30% saving), but if we remind ourselves that the first core of processors consumed 22 W, then the new level is simply astonishing. However, as the principal change for us should be identified the improvement of the potential overclocking. Overclock with 3.6, 4 gigahertz and even higher are subjected daily with the new processor, the new revisions appreciably improved the result of overclock using cooling with the air even without increase of the vcore of defect, moreover this improvement is not only for the core duel, but also for four processors of core.
To check the overclocking possibilities, we took three the duet e6550 core 2 of Intel of processor. They all work on the bus of system 333 megahertz, their frequency of defect is 2.33 gigahertz, they have the hiding-place of 4 mbs on the second level, ALL these processor are assembled in Malaysia and have inscription SLA9X.

.
The processors referred to a part, but their numbers of series differed (by several thousand).
Here the component of material used for this test:
- Mother chart: abit IP35 pro v1.00, BIOS 1.0;
- Processor: duet of core 2 of Intel e6550 (2.33 gigahertz, FSB 333 megahertz, 4 mb., Conroe, rev. G0);
- Memory: dominator TWIN2X2048-9136C5D of corsair of the mb 2x1024;
- Video chart: Mb of the geForce 8800 GTS 320 of NVIDIA. ;
- Hard drive: barracuda 7200.10, ST3320620AS, 7200 RP/min, of seagate mb 16. , SATA of 320 gigaoctets;
- Cooling system: CNPS9700 zalman LED;
- Unit of power: gameXStream of OCZ GXS700 (700 W).
The exaggeration of the frequency of processor of defect is an index property of mother chart of abit, this time when the processor functioned 47 megahertz more top than its defect; however, the processor with similar arrangement did not function without any problem, here the mother chart at time with vacuum (the tension and the frequency of processor are decreased).
CENTRAL PROCESSING UNIT OF TREATMENT the utility of Z reflects the voltage incorrectly. The core-temp largely known of program not only cannot show the correct temperature, but also made errors in the frequencies, and even in the name of processor.
The Speed-Ventilator put 'exposure of T any extra informations, the only liquid asset is the temperature of hard drive! ! ! !.
It was necessary then to install the utility of abit (3.1.0.4 version of �Guru). This utility correctly detected the change of the temperatures and the tension.
The tension of defect in all the examined processors is 1.35 v: it is larger than evaluate earlier met with older models and also the maximum of central processing unit of treatment for this processor.
Directly let us pass to the results of overclock, the first processors examined without increase in the vcore proven to be completely stable and operational at the frequency of FSB equal to 480 megahertz!
Like comparison: the duet e6300 of core 2 of Intel of processor, which we usually used for the test of mother chart, was able with the overclock up to 490 megahertz, but with the increase in the vcore at 1.45 v!
Overclock with 3.36 gigahertz with the vcore of defect is rather good result; however, since the FSB was already high, do not should exclude to us a frequency much higher of this processor due to: Wall of FSB, mother chart or possibility of memory. : - (
With FSB 520 megahertz the refuse of system to be initialized even with lowered to the multiplier (x6) minimum, with 510 megahertz we could reach windows but only several seconds after a gel, then to 505 megahertz it was possible to run this stability of processor.
To carry out this result which it was necessary the vcore to increase processor of the v of the defect 1.35 to 1.45, tension on the bridge of north was also climbed of 1.25 up to 1.52 v, the central processing unit of treatment VTT was climbed of 1.2 to V. the 1.31 temperature during the half an hour checking using the program of OCCT (according to the utility of �Guru of abit) was only 45c.
Let us pass to the second processor, we immediately began our test with the vcore of central processing unit of treatment of defect and frequency of regulated FSB with 490 megahertz. But here. ! ! ! The system refused to initialize at this frequency and also to 480,470,460 megahertz. Thus we decreased the multiplier with x6, and disappointment was that the system refused to initialize at the frequency of FSB 450 megahertz. It is an example of low value of wall of FSB. With 440 megahertz FSB the processor was able to charge Windows, but it was not stable in the tests, stability was possible only with 430 megahertz. frequency
Probably, this processor could function at the frequency of FSB 435 megahertz, but we did not check stability with such an arrangement.
The last processor proved to be just better than the second. It can initialize with 460 megahertz of frequency but not more, tests cannot passes 455 megahertz from frequency, the maximum frequency of stable FSB was of 450 megahertz and also here without increase in vcore.
Conclusion
The results showed that the duet e6550 core 2 of Intel of processors is not only impressive, but also discouraging. New G0 taking a step show really excellent possibilities of overclock. Other side, let us note that the overclock is right as a lottery U can obtain good or bad processor.
To at the same time should identify us that the duet e6550 core 2 of Intel of processors because their duet e6300 and E6320 of core 2 of Intel of predecessors, are imperfect choice for the overclock. Because of low of defect of the multiplier (x7) of witch their potential overclocking limits completely. Overclocker should seek the duet e6750 core 2 of Intel of processors with the multiplier x8 (2.66 gigahertz). But what if their wall of FSB will prove to be limited by frequency 400 megahertz? ? ? ? .....
The price of the following model: the duet e6850 (3.0 gigahertz) of core 2 of Intel will be compared with the cost four of the bottom-of-the-range quadruple q6600 (2.4 gigahertz) of core 2 of processor of core.
Until the economic overclockers, which prefer not to spend on the processor considerably more than $100. The choice is limited to the duet of core 2 of Intel of processors e4500 (2.2 gigahertz) and e4400 (2.0 gigahertz), functioning with 200 the bus of system (of 800) megahertz and is based on the new M0 progression: this reduces the version (hiding-place of 2 mbs). Such a processor makes allow the high witch x10 and x11 of multiplier the ovoid problem with the mother chart, the memory and of the limits of the wall of FSB.
