Want to squeeze a bit more performance out of an OLPC? Then check out this topic at OLPC News Forums that explains how to overclock the system's AMD Geode LX 700 CPU.
By overclocking your OLPC you are running the hardware outside the design specifications.
Overclocking your CPU and/or RAM may cause stability problems, data errors, and possibly
hardware damage. As the OLPC is passively cooled, physical damage could easily be
caused by excess heat.
The procedure detailed below is relatively safe, cpu and memory voltages are not changed,
as that appears to require a hardware hack. The system is overclocked for a single boot
only, and must be entered manually any time you wish to overclock. The system could be
modified to perform this automatically every boot, but I will leave that exercise to others.
