♦ This mainboard has a Socket-478 support for Intel Pentium4
processors with front-side bus (FSB) speeds up to 400 MHz.
♦ Supports two DDR + two SDR DRAM
Socket-478 Processor
♦ Supports Intel Pentium 4 series CPUs
♦ Supports up to 400 MHz Front-Side Bus
Memory Support
♦ Two 168-pin DIMM slots for SDRAM memory modules
♦ Two 184-pin DIMM slots for DDR SDRAM memory
modules

Notice: YOU can NOT work SDRAM and DDR simultaneously.
Installing Memory Modules
This mainboard accommodates 168-pin 3.3V/184-pin 2.5V
unbuffered SDRAM memory modules. The memory chips must be
standard or registered SDRAM (Synchronous Dynamic Random
Access Memory).
The CPU supports 100MHz system bus. The SDRAM DIMMs
and DDRs can synchronously work with 100 MHz or operates over
a 133 MHz memory bus.
You must install at least one memory module in order to use
the mainboard, either SDRAM or DDR SDRAM, but you
cannot use them simultaneously.
Note: Please be noted you must set up the correct jumper settings
(JP1 and JT1~JT10) as described in page 13 of this chapter.
SDRAM provides 800 MB/s or 1 GB/s data transfer rate
corresponding with the bus 100 MHz or 133 MHz. It doubles the
rate to 1.6 GB/s and 2.1 GB/s by transferring data on both the
rising and falling edges of the clock. DDR SDRAM uses additional
power and ground lines and requires 184-pin 2.5V unbuffered
DIMM module rather than the 168-pin 3.3V unbuffered DIMMs
used by SDRAM.
CPU-Z kaže slijedeće (za procesor):
Bus speed: 100
Rated FBS: 400
Za memoriju kaže:
DRAM frequency: 133 MHz
FSB:DRAM: 3:4
CAS# Latency (CL): 2.5 clocks
Unutra se nalazi 1.7 GHz procesor te 256 MB DDR memorije (PC2100, 266 Mhz). CPU-Z pokazuje da memorija radi na 133 MHz, no ona navodno efektivno radi na 266 jer je tip memorije dvokanalni pa te dođe 266.

Pitanje: Koje tipove memorija ovo računalo podržava? Kakva je veza (ne teoretska, već u praksi) između procesora, FBS-a i takta memorije? Unaprijed svima hvala.
