Checking the status of your G3
In the Control Panels folder of your start-up drive, open the
MACh Speed G3 Control, either by double-clicking it in the
Control Panel folder on the desktop, or by selecting it via the
Control Panel’s hierarchical menu in the Apple Menu Items.
In addition to controlling the backside cache of the G3

Chapter 3 - MACh Speed G3 Control Software
Using MACh Speed G3 Control software
Operation of the software is fully automatic. It has numerous
features for added compatibility and performance.
The first time the machine starts up with the software
installed, the MACh Speed G3 software will assess the
capabilities of the backside cache and establish the
n e c e s s a ry settings automatically.
• Any time the CPU speed is altered more than 2%,
or if it detects a crash immediately following the
enabling of the cache, the software will again test
the cache on bootup and provide revised settings.
• Sometimes the cache testing will reveal that a faster
backside cache speed may be usable even if it is not
supported by the card manufacturer. The software
will present a dialog box at startup offering to use
the faster speed if desired.
Default Override Dialog
Note:
In certain cases, the manufacturer of the card may
in fact support the faster speed. In these circumstances,
you can allow the software to run the faster speed. For
example, users of the MACh Carrier 300/200 should
always choose 200 MHz instead of the default 150 MHz.
