   NMI Errors on Reply 8580 - SIMM compatib

   I'm trying to upgrade the SIMMs in my 8580 with Reply Turbo Board with 16MB   
   ones, but every single stick I have gives me random NMI (parity) errors. All   
   my sticks are 9-chip 60ns Kingston branded. I've tried both parity and ECC   
   (separately of course,    
   both are supported according to the manual). There's no way I have more than a   
   dozen dead sticks, so there must be some some sort of compatibility issue here.   
      
   As far as I can tell, the fastest this motherboard takes is 70ns. Is it   
   possible the ram is somehow unsuitable because it's too fast? Or is it   
   possible that the motherboard doesn't like the chip configuration that these   
   sims use (9-chip vs. 12-chip, etc)?   
    The motherboard works totally fine with the original 12-chip 70ns 4MB sticks,   
   so I don't think the planar is broken.   
      
   Anyone have any idea what could be going on?
