  <div class="attr SUMMARY">
Combining parity and non-parity RAM in a non-parity Macintosh IIfx should<BR>
not be a problem as long all the SIMMs in each SIMM bank are the same<BR>
speed.  We have seen some problems using SIMMs from different vendors in<BR>
the same SIMM bank, even though they have the same speed.  This is<BR>
probably due to speed differences between the SIMMs.<BR>
