Famous Japanese overclocker who calls himself Memesama has set a yet another world’s record in overclocking Intel Pentium 4 processor. This time the well-known computer enthusiast achieved 7.30GHz speed.

According to the statement issued by Memesama in his blog as well as in XtremeSystems web-site’s forum, the system managed to calculate π (pi) number to 1 million decimal places in approximately 17 seconds, which is the world’s record of today. Core-clock of 7304MHz is also the highest speed Intel Pentium 4 processor ever achieved. Earlier clock-speed record breaking – 7.13GHz – also belongs to Memesama.

The experiment was conducted on virtually the same system that was used to set the previous world’s record in both Intel Pentium 4 clock-speed as well as SuperPI benchmark result, but this time even higher microprocessor voltage was set.

In particular, Memesama used ASUS P5WD2 Premium mainboard powered by Intel i955X chipset, Corsair PC2-5400UL 512MB memory modules as well as Intel Pentium 4 670 processor with stock speed of 3.80GHz. The processor system bus was overclocked to 1537MHz; processor’s voltage was pumped up to 1.86V, significantly higher than default setting; memory latency settings were CL4 3-3-4, memory voltage was set to 2.26V. Liquid nitrogen was used for cooling down the microprocessor.
