Installing System Memory
【
DRAM 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. Two 72-pin SIMM sockets:
Currently, the most common memory modules on the market are 72-pin
SIMM modules. The two 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 60ns FP or EDO
modules.
If your memory modules are faster than 60ns, say 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 430TX 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.
