We already reported that wolfdale processors E0 stepping noticeably improved their overclocking potential, and the majority of fresh world records in various application are made using this stepping .
The processor core 2 Duo e8600 (3.33 GHz), not only possesses a high default multiplier (10x), but also based on new stepping E0. This processor model in separate regions already appeared on sale. Here is the E8600 processor under liquid nitrogen at 6467 MHz frequency .
Using active air cooling this processor preserves stability at the frequency up to 4.8 GHz, and it is even possible to get a screen shot at 5.0 GHz !!! Regular box cooler allows the processor core 2 Duo e8600 to reach the 4.5 GHz under load, and the frequency of 4.0 GHz completely stable with voltage close to the default
.
Note this is not the special feature of this single copy, but the general impressions of first E0 processors owners . In this case one engineering model core 2 Duo e8600 with air cooling preserved the ability to execute super PI 1M at 4.96 GHz frequency .
Note also core 2 Duo e8500 (3.16 GHz) processor old stepping C0 was able under liquid nitrogen to overclock up to 6544 MHz. TaPaKaH was able to overclock the E8600 to 6376 MHz in this case the processor executed the super PI 1 MB test in 7,140 seconds.
