Aperacer sets five records with Intel Atom N455 mobile processor

Today, Italian overclocker aperacer published five rather interesting results achieved with the old Intel Atom N455 mobile chip. These results are particularly notable because they involve relatively unconventional overclocking methods for laptop processors. For instance, to cool the boosted CPU, the Italian had to disassemble the ASUS Eee PC 1015PE (Seashell) test laptop and attach small video memory heatsinks to the CPU's copper heatsink cover using thermal paste:

But that's not all. Due to reliability and longevity considerations for mobile devices, laptop BIOSes are significantly simplified, often lacking basic functions for CPU or RAM overclocking. Therefore, aperacer had to use a software-based overclocking method, specifically the SetFSB utility.

Using SetFSB, the Italian managed to overclock the Atom N455 processor to an impressive 2223MHz (the chip's base frequency is only 1660MHz), securing first place in the model ranking for the CPU.

The FSB frequency was 223MHz, core voltage 1.025 volts, and the SK Hynix 2048MB (DDR3-1337) memory (P/N: HMT325S6CFR8C-H9) ran at 889.4MHz with 5-5-5-12 timings.

Beyond the frequency ranking, aperacer also collected four gold medals in the following disciplines: SuperPi - 1M, SuperPi - 32M, wPrime - 32m and wPrime - 1024m.

Here are the benchmarks and their results:

For this setup, a disassembled ASUS Eee PC 1015PE laptop served as the test bench. However, the device was somewhat modified; for instance, its hard drive was replaced with a SAMSUNG SSD 830 Series (FW: CXM03B1Q) SSD.
