¯ Installing System Memory
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:
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 do not support this feature on
this mainboard.
Since the Intel 430VX chipset does not support this feature, since the
memory error check and correction feature may not be effective, and
since you cannot easily find memory modules with memory check and
correction feature, this mainboard does not support it.
