Techpowerup spotted on a Chinese forum that Intel's upcoming Pentium Dual-Core E5200 processors overclock like a dream. These chips are based on the 45nm Wolfdale cores and have a clockspeed of 2.5GHz but the overclocker managed to crank up the frequency of his engineering sample to 4GHz:
This processor is based on the 45nm Wolfdale core and features a total of 2 MB L2 cache. It has a default 200 MHz FSB and 12.5 x FSB multiplier and clock-speed of 2.50 GHz. Owing to this high multiplier and the Wolfdale design, this chip facilitates high overclocks, Coolaler.com has been able to take this chip to 4.00 GHz core with a FSB of 320 MHz and Vcore of 1.384 V. More than impressive for a budget processor.
