MK79 Online Manual DI M M ( D u al I n Li n e Me m o r y M o d ul e) DIMM socket has total 168-pin and supports 64-bit data. It can be single or double side, the golden finger signals on each side of PCB are different, and that is why it was called Dual In Line. Almost all DIMMs are made by SDRAM, which operate at 3.3V. Note that some old DIMMs are made by FPM/EDO and only operate at 5V. Do not confuse them with SDRAM DIMM which operates at 2.5V..
MK79 Online Manual E E P R O M ( El e c t r o ni c E r a s a bl e P r og r am m a b l e RO M) 2 Also known as E PROM. Both EEPROM and Flash ROM can be re-programmed by electronic signals, but the interface technology is different. Size of EEPROM is much smaller than flash ROM. E P R O M ( E r a s a b l e P r o g r a m m a b l e R O M) Traditional motherboard stores BIOS code in EPROM. EPROM can only be erased by ultra-violet (UV) light.
MK79 Online Manual Fl a s h RO M Flash ROM can be re-programmed by electronic signals. It is easier for BIOS to upgrade by a flash utility, but it is also easier to be infected by virus. Because of increase of new functions, BIOS size is increased from 64KB to 256KB (2M bit). AOpen AX5T is the first board to implement 256KB (2Mbit) Flash ROM. Now flash ROM size is moving to 4M bit on AX6C (Intel 820) and MX3W (Intel 810) motherboard. , AOpen motherboard uses EEPROM for jumper-less and battery-less design.
