The following DockMaker document shows the performance curves generated
>From 25 to 36 MHz based on benchmarks run on a Quadra 700 with the
Variable Speed Overdrive, and having placed pin sockets for the 50 MHz
crystal. This is sort of a follow up to Guy Kuo's reports on replacing
the crystal for a higher frequency one. I hope you find it useful if
you're trying to select an appropriate speed or, if you just wonder what
kind of beast lies inside that box. All of this came up after exchanging
some e-mail with Guy and finding on both of our machines a zone of
no-tolerance (with VSO around 33 MHz).
In my particular case I found an optimum range of speeds with no
performance degradation.
Netters complained on the file format, so I re-worked the Excel doc,
rearranging the spreadsheet data, and normalizing it to improve the
quality and readability of the charts.
(Now you know the percentage of improvement right from the chart). And
made it a stand-alone document.
Please let me know if you like the Excel doc better, so I will post it.
Please post where ever appropriate
