Memory
Configurations
The memory is fitted in four vertical DIMM sockets which must be
populated with gold, 3.3V, 72-bit DIMMs. 80, 70 and 60ns timings are supported, but 60ns
results in much tighter memory control and may considerably improve system performance
with some software. Although the minimum configuration is one DIMM there are considerable
performance benefits in fitting more than one DIMM. 2-way or 4-way interleave become
available when two, or four DIMMs respectively, are fitted. All four must be same speed.
Note that these DIMMs are buffered and are not the same as those used
with the PCL6000 motherboard.
