03.031 Ever since my accelerator speed upgrade it seems like my GS is always experiencing random system crashes. What's the problem and how can I fix it?

         When a GS equipped with an accelerator experiences frequent crashes into
the monitor after a speed upgrade, the usual explanations are ...

  1. the accelerator is over-clocked for the microprocessor or RAM;

  2. there are serious noise spikes on the Slot power lines.

     If you are 'pushing' your current RAM or using an old 65C816, you can
upgrade to faster chips or swap in a slower oscillator.

     Often, the problem will be noise spikes related to increased current load
and/or increased sensitivity to noise related to faster clocking. See the POWER
FAQs for Power Supply and motherboard mods which should help.
