NOTES

A 1.33GHz (10x133) processor has been overclocked with core voltage adjusted
from 1.75V to 1.80V. In addition, memory voltage has been increased from 3.3V
to 3.5V. An unknown cooler by Maxtron has been installed (a 80mm 3000rpm ball
bearing fan + an aluminium radiator).

The mainboard has been populated by poor Chinese electrolytic capacitors
manufactured by GSC mostly. Many of them have blown up. Almost all of them have
been replaced with quality Japanese and Taiwanese ones (by Rubycon and OST
mostly), and about two dozens of MLCCs have been added to reduce high-frequency
voltage losses for the processor and memory modules.

Non-ECC memory has been installed (ECC function isn't supported by the system
logic). 4-bank memory interleaving and fast read\write turn-around have been
enabled in the BIOS. tRCD and tRP are hardcoded and not user changeable.
