Sites - they are as human beings. Most frequently reported fairly mundane things, sometimes lepechut any nonsense, but occasionally razrozhdayutsya virtually revelations. Our site said their votes authors and articles Gavrichenkova Ili, a typewriter, under the nickname Gavric, often can be attributed to the third type. It happens that his work did not receive deserved attention, pass almost unnoticed. So, in my view, wrong article "PC2-9200 and PC2-10000 SDRAM: ultraskorostnaya memory from Corsair and OCZ. I agree that ultraskorostnaya and ultradorogaya interesting only memory units, but this boring headline hides a very interesting (and useful from a practical point of view) comparison of DDR2 memory systems operating on different frequencies and with different taymingami. What to choose: greater bandwidth with the same long delays or lower frequencies, which will allow aggressive timings to take advantage of low latency? Article provides an answer to this question, considering the situation in the systems in nominal mode and to disperse, but, judging by the number of reads, very few have benefited from this research.

Quite different from the fate of other work - "Mnogoyadernaya confrontation: Core 2 Quad Q6600 against Core 2 Duo E6850. Tens of thousands of Reading, mnogostranichnoe (but, unfortunately, most of pustoporozhnee) discussion in the conference - neglected art is left. Wonder, because the results, at least for me, were amazing and unexpected. Until now, I was absolutely confident that the Quad processors are interested in only a narrow circle of persons using very specific and limited set of applications specifically optimized for multi-CPU. Duration of these processors is only a few years old, and yet they represent the range polubespolezny makeweight ordenonosnyh dual-processor Core. However, it turned out that the situation is drastically different! It is not surprising that in the specialized programs Quad Core 2 is ahead. It is amazing that he is ahead of Core 2 Duo in most "normal" applications, such as games, even with the backlog in the frequency!

One article, by definition, can not provide answers to all the questions raised some doubts after reading this. The first and most obvious problem - temperatures. Accept that you can not accept the normal processor at a temperature approaching close to 90 ° C. The second point - Processor Core 2 Quad Q6600 stepping G0 was broken up with a 2.4 to 3.6 GHz. And, on average, before any frequency dispersed Quad processors Kentsfield? Our statistics does not disperse until a reliable answer to that question, only recently the price of these processors were cut, too few results disperse these processors. Moreover, there is no guarantee that you hit processor Core 2 Quad Q6600 desired stepping G0, now strewn market unsold because of the high prices and lack of demand for processors old steppinge B3. So what we get final results, if we take in the near store several processors to disperse and try to keep the temperature within acceptable?

To check, we have received three processor Intel Core 2 Quad Q6600. By marking SL9UM easy to find their characteristics website producer. As expected, they are based on more old steppinge B3.

In nominal mode processors working on the tyre 266 MHz (1066) with the factor x9, which ultimately gives the frequency of 2.4 GHz. Formally, a quad-processor Kentsfield "glued" dual pair of Conroe, so the total volume of the cache memory is impressive 8 MB. Processors collected in Malaysia belong to one party, the serial numbers of the first two followed one after another, a third processor different number several hundred.

Motherboards abit known that deliberately overstate the frequency of tires, so the frequency of the processor on the screenshot above nominal.

Intel Core 2 Quad Q6600 of high heat release by modern standards, but in the rest of their multiplication factor and voltage reduced.

The tests were carried out in the open test bench the following configurations:

Acceleration processors conducted in accordance with the simple principles set forth in the articles "How to overclock processors (Picture Book)" and "A few tips for beginners overklokeram." To begin with, it was possible to set a minimum frequency of memory, slightly increased the stress on it, but no more than increased tension. By the way, staffing Vcore voltage to all processors at 1,325 B. For a preliminary assessment of the stability of the work used 15 - minute test program OCCT for temperature control CoreTemp utility. Then, to ascertain the limits disperse while increasing strain on the processor. As processors have high multiplier, to disperse they do not reach the high frequency FSB, and no other action to ensure stability was required. Subsequently, in order to increase the frequency of work to the maximum possible memory frequencies needed to raise the voltage on the north bridge chipset.

The first and third processors were completely identical in their overklokerskim opportunities. Without increasing the Vcore voltage they earned at a frequency of 340 MHz tires. After the voltage was increased to 1.45 V, processor efficiency has been achieved at a frequency of 370 MHz. Temperature range was not as high as I expected. In the rest, when energy-saving technologies processor temperature does not exceed 40 ° C under load varied in the region of 52-55 ° C. When the voltage temperature naturally increased. In the rest, it was 40-47 ° C and under load 72-75 ° C.

The second processor is different from the first and third for the better. When he earned a nominal voltage at a frequency of 350 MHz.

It must be said that he was "cooler" than the other two processors. In an equal footing his temperature was markedly lower than they have. In connection with this Vcore voltage was increased to 1.5 V without any changes in temperature, compared with 1.45 in a pair of twins-processors and reward became the second processor operating at a frequency of 380 MHz.

During the preliminary test was recorded maximum temperature of 74 ° C, mainly as it fluctuated in the region of 70 ° C. Utility OCCT provides uneven load testing at half maximum rose to 77 ° C, but the average temperature remained unchanged.
