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. 168-pin DIMM sockets:
¶
AX5 support three 168 pin DIMM sockets
·
PX5/TX5 support two168 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. 72-pin SIMM sockets:
¶
AX5/TX5 support four 72 pin SIMM sockets
·
PX5 support two 72 pin SIMM sockets
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
