Description: 8rdavcore is able to set voltages (VCore, Vdd, Vdimm, Vagp) and the FSB on different mainboards.
Configuration of chipset settings like memory-timings and controlling the fan speed (depends on board) is also possible.
OS: 8rdavcore runs under 2000/XP (9x/ME)

Help and Tips

This version uses the GiveIO.SYS driver (under NT/2000/XP) and try to automatically install it. If this doesn't work you can install the driver manually: giveio.zip
You can uninstall the driver with the Device-Manager,
VIEW->Show all devices (or something like that), Non-PnP-driver->giveio. Or use remove-giveio.zip


- Run prime95 or something similar where you can see if a overclocked or undervoltaged processor produces errors.
- Use small steps to find a limit (VCore 0.05V, FSB 4Mhz)
- For my 8RDA+ this works: minimal FSB = (FSB at boot-time)-60, maximum FSB = (FSB at boot-time)+10
- 'Sensor' shows the measured voltages from the Winbond/ITE hardware monitor
- The CPU temp is from the socket (on 8RDA), not the internal diode
- Differences between theoretical and sensor values (+/- 0.05V) are normal
