Chipsets are also important as they determine the efficiency of RAM and Expansion
slots
• Intel 915 supports up to 533MHz PC4200 DDRII RAM
• Intel 925 supports up to 600MHz PC4800 DDRII RAM
All current and popular AMD formats use DDR RAM, with the standard
400MHz PC3200 being most common. Most Intel socket 478 processors also use
the older DDR RAM
The function of BIOS is highly important. Some BIOS features crash proof
functions essential for updating the firmware. Other motherboards allow BIOS
control of overclocking of CPU, RAM and Graphics card which are much more
stable and safer for overclocking. Newer BIOS have temperature controls, and
functions that shut down the computer if the temperature gets too high.
