Hardware Tips

(not to be confused with memtest86 or memtester)

  • Keyboard is recognised and works only if the N-Key Rollover DIP switch isn't on (for versions including and up to 6.10). Reboot between switch changes.
  • Dust really does make a difference for the contacts! If you see dust on the casing of your RAM sticks, but the contacts look clear don't assume the dust won't somehow obey the laws of gravity and end up making its way to the sockets. >_<
  • My favourite way to remove dust is to use a camera lens blower + vacuum cleaner. The vac must only be used at a distance to collect all the dust from the air that the lens blower throws up. I've never zapped a component with this technique. Keep the PSU earthed (plugged into the power outlet but switched off) of course, so you can touch it to regularly ground yourself.
