° Installing System Memory¡i
When this mainboard was designed, we not only have taken into account
the present needs, but we have also tried to care about demands for future
upgrades:
1. Two 168-pin DIMM sockets:
Within 3 to 5 years, you may not be able to buy 72-pin SIMM
memory modules anymore, just as now you cannot find 30-pin SIMM
memory modules anymore. If you want to extend your memory
capacity, you will have no solution other than to use 168-pin 3.3V
unbuffered DIMM sockets.
2. Four 72-pin SIMM sockets:
Currently, the most common memory modules on the market are
72-pin SIMM modules. The four 72-pin SIMM sockets of this
mainboard will meet your needs.
3. Easy installation
You just need to insert the modules, without the help of God. Isn' t it
great?
Besides the features mentioned above, you can use simultaneously 72-pin
SIMM modules and 168-pin DIMM modules, but you will rarely encounter this
kind of configuration. Before you proceed with installation, be patient, first read
what follows:
1. Factory default setting of the mainboard is for 70ns FP or EDO
modules.
If your memory modules are faster than 70ns, say 60ns or 45ns, you
can modify the BIOS settings in order to speed up the operating speed
of the system. But if you don' t want to modify these settings, or if you
don' t know how to modify them, it' s no big deal.
But if you set the external CPU clock at 66MHz or more, we
recommend you use 60ns or even faster DRAM modules.
2. Memory error check and correction feature on this mainboard.
