The first acquaintance with the overclocking characteristics of processors Core 2 Extreme X6800 (2.93 GHz) stepping B2 has left double sensation: on one hand, stepping b2 is the freshest and to wait the best results is necessary; on the other hand, stepping B2 already studied could not surpass the first copies of processors B1 in overlcoking.
we have today studied an additional processor core Duo E6xxx steeping b2 to clear out those issue
The first processor steeping B2 was overclocked using water cooling, already system and Gigabyte GA-965P-DQ6 motherboard. evreythink was at stock we had not applayed anyvolt mod, overclocking has been achieved only with regular motherboard parametre. The vcore voltage of the processor has been increased till 1.49-1.51 v, the voltage on the of north bridge chip has been increased by 0.25 v .

So, the overclocking result of 3.5 GHz with the water cooling can not impress , however for processor Conroe with the maximal multiplier value of 7x is very good result. As you can see, frequency of the system bus has reached 501 MHz. The limited capabylity of the motherboard on increase of bus limited the overclocking of processors Conroe, and hardly the situation will essentially change in the near future.

Let's notice, that the multiplier has been increased to reash this value. If we use a liquid nitrogen cooling, it is possible to reach frequency of 5.16 GHz using both cores.

Let's remind, that the current overclocking record is 5.5 GHz using one core and voltmod. The record holder still a B1 stepping cpu cooled by liquid nitrogen,super pi 1 m test was done in 9.156 s .
There is many b2 steeping cpu witch showed good overclocking potentiel but the probleme still with motherboard fsb capability
