Overclocking

Clockspeed

The is CPU frequency is calculated by multiplying the FSB with the multiplier of the CPU. Front-Side-Bus (FSB) frequency is the speed between the CPU and Memory Controller (ICH6), and quad-pumped (4x bus speed). The DDR2 Memory speed is between the Memory Module and Memory Controller, it's double-pumped (2x bus speed) and dual-rated. The bus speed is the base clock speed provided by the Phase-Locked-Loop generator.

Windows

Currently the only way to overclock in Windows is by using a program called SetFSB, by Abo from Japan.

The stock 0401 BIOS did not allow for much overclocking. Reverting back to the earlier 8804 BIOS version allowed for impressive results, 997.6 MHz before crashing. For some reason I can't get it over 1 GHz, a problem with the program or PLL maybe?

The current version of SetFSB doesn't support the correct ICS9LPR426AGLF PLL chip yet, but I have contacted the author and he will try to add support for it. In the meantime, it's possible to use the similar ICS9LPRS906CGLF instead. The DDR and PCIe speed ratings are improperly reported, but it's still possible to change the FSB.

Update: I've received a new version that works with ICS9LPR426AGLF support, download 2.0 build18q. The update allows for PCIe overclocking, and the correct speed ratings are reported for CPU/DDR/PCIe/PCI.

Linux

To get the actual processor speed in linux, the 'p4_clockmod' module has to be unloaded, 'rmmod p4_clockmod'. Get the CPU information by 'cat /proc/cpuinfo' in a terminal window.

The temperature can be found by executing 'cat /proc/acpi/thermal_zone/TZ00/temperature'.

CPU/FSB Speed Limit Workaround

It's possible to run the stock 900 MHz on the latest BIOS version by clearing the CMOS and booting-up. The CPU is not reset to 630 MHz after being prompted to press F2 to load the default settings, allowing to run 900 MHz until the next system reboot.

Clear the CMOS by:

When booting up press F2 to load default settings and continue to load the operating systems on 900 MHz.

Wifi is disabled by default but can be enabled by pressing FN+F2 (Wifi icon) and the blue Wifi LED should light up. Webcam is different and currently I only know how to enable it in Linux. Execute this command in a terminal: sudo echo 1 > /proc/acpi/asus/camera

Wifi

After installing the new draft-N adapter I haven't had any problems or disconnects that some people are experiencing. On a 802.11g network I transferred files at 2.6 MB/s for an hour without problems.
