Q: Why the AOpen mainboards (MB) do not have cache module expansion
slot?
A: Faster CPU speed requires more difficult and complex MB timing design.
Every trace and components delay must be taken into consideration. The
expansion cache slot design will cause 2 or 3ns delay in PBSRAM timing, and
the extended trace length to the cache module through the golden finger will
further delay the timing by 1 or 2ns. This may result in unreliable system
once the cache module and slot becomes worn. All AOpen MBs support
512KB PBSRAM onboard. For better performance (around 3% higher than
256KB), we strongly recommend you to use 512KB onboard. Otherwise,
reliable 256KB is better than unreliable 512KB with cache module. AOpen is
the first company to promote this concept since the fourth quarter of 1995.
