Intel Core 2 Duo E4400, 6320, 6420

[Panoramix0903]

O chvilku - v aprili tohto roku - pridu na trh tieto procesory od fy. Intel.


Core 2 Duo E6420
2.13 GHz
1066 MHz
4 MB L2 cache

Core 2 Duo E6320
1.86 GHz
1066 MHz
4 MB L2 cache

Core 2 Duo E4400
2.0 GHz
800 MHz
2 MB L2 cache



Predpokladam, ze hlavne 6320 bude velmi oblubeny pre pretaktovanie. Blizsie info tu:

a tu je nieco blizsie k novym cipsetom P35 a X38

4MB L2 za babku - len aby siel tak dobre OC ako (prinajmensom) E6300

Postaci ti to ako odpoveD?

As a result, the overclocked CPU was working stably at 3.72GHz, which is 75% higher than the nominal. This is very good and impressive result, which makes Core 2 Duo E6420 a very attractive choice for overclockers.

We can conclude that Core 2 Duo E6420 processors can overclock as good as their elder brothers. And this is actually not surprising at all, because with the Core 2 Duo E6x20 the youngest CPUs on Core micro-architecture acquired fully-fledged Conroe core.

The second testing participant to undergo some overclocking was Core 2 Duo E6320 with the nominal multiplier of 7x. Note that this processor is harder to overclock because of the high clock frequency multiplier, which we have already mentioned before during our Core 2 Duo E6300 overclocking experiments. In order to achieve maximum frequencies for the Conroe core, the mainboard may need to allow raising FSB frequency beyond 500MHz, which far not every mainboard can do, even from a leading mainboard maker. Moreover, you are more likely to hit against the “FSB Wall” – the maximum FSB frequency for the given processor that is not connected with its clock speed.

As for the practical results, our Core 2 Duo E6320 with the nominal Vcore of 1.3125V could speed up to 3.29GHz without any core voltage increase. It is equal to 470MHz FSB.
