Installation EP-BX3
Page 3-4
Note: Based on the implementation of Intel 440BX PCIset, EP-BX3 is able to
provide two host bus frequencies -- either 66 or 100MHz for Slot1 processor and
memory operating. The default is set at 100MHz once Pentium
® II processor to
be mounted onto this mainboard. However, no matter what kind of Slot1 proces-
sor you installed, it should come with right memory modules for normal and stable
operation. For example, if you install a Pentium
® III processor, you should use
the SDRAM module with 100MHz based(or above) to match the CPU speed.
Furthermore, one thing you may need to bear in mind, before the CPU installation, it
is anyway our advice to use JP3 and set up right speed of Slot1 processor at any
time.
