3-2
processor are identical, The major difference between these two processors is the
boxed CPU has head sink, cooling fan and heat sink supporter, while the OEM
Pentium™ II CPU doesn’t. As for the Celeron™ processor, it will need the
different mechanism to hold the CPU, please check with your CPU supplier for
the require materials.

INSTALLING THE DRAM MODULES
The 443BX chip integrates a main memory controller that supports a 64-bit
DRAM interface. The DRAM controller supports the following features:
1.
DRAM type: Synchronous (SDRAM) DRAM.
2.
Memory size: 8MB to 512MB.
3.
Memory modules supported: Single and double density 3.3V DIMMs.
4.
DRAM speed: 60ns for asynchronous and equivalent SDRAM 100/66
MHz parameters for synchronous memory.
This mainboard supports four 168-pin DIMM sockets (DIMM1, DIMM2,
DIMM3 and DIMM4), each DIMM can be single-bank or double-bank, 8MB up
to 512 MB of local memory can be populated on the board. Only the
Synchronous (SDRAM) memory is recommended because it will give a better
performance. (Both Symmetrical and Asymmetrical DRAM addressing are
supported.),.
This mainboard provides a DIMM plug-and-play support via Serial Presence
Detect (SPD) mechanism supported via the SMBus interface. In order to give the
best performance to the PC system, the DIMM module with SPD is strongly
recommended especially when installing the 100MHz processor to the board.
The SDRAM module with SPD is designed to increase the system performance
and make system more stable and compatible at the same time. When the system
BIOS detects the SPD DIMM module populated on the mainboard, the system
BIOS will retrieve the information (such as DRAM type, size, access timing ...
etc.) which is stored in the DIMM module. The system BIOS will then use such
information to determine what operating parameters will be used for individual
DIMM module automatically and gives the best performance and reliability to
your PC system.
