Core i7 processors on D0 stepping already began to enter stores. Some overclockers consider that the overclocking potential was improved after transfer to the new stepping, others were assured that among C0 processors, there is the identical copies (in terms term of overclocking).
Associate tested several processors core i7 D0 stepping (both engineering models and series copies ).
The conclusion, gladdens the majority of overclocker: D0 stepping brings an improvement in the overclocking potential. Higher frequencies are achieved by lower voltages, and the heat emission level was reduced. Stable overclocking to 4309 MHz with one of the series processors core i 7-920 (2.66 GHz) stepping D0 was reached with 1.345 v.
Victor wang overclocked the engineering model core i 7-975 Extreme edition. This processor was based on D0 stepping. With 1.44 v this processor was overclocked to 4677 MHz, after preserving stability in the test superPI 1M. The processor in this case was cooled with water cooling systems. Related Products :
