Different software is used by different motherboards. There are also third-party programs that work on a variety of motherboards and allow wide customization of fan behavior depending on temperature readings from the motherboard, CPU, and GPU sensors, as well as allowing manual control. Two such programs are SpeedFan [11] and Argus Monitor. [12]
Some motherboards have a built-in display to diagnose hardware problems. Most also report POST errors with audible beeps, if a PC speaker is attached. Such motherboards make POST cards less necessary. When these diagnostic cards were first introduced motherboards were expensive and well worth troubleshooting and repairing.
Power supply, system board problem, disconnected CPU, or disconnected speaker Continuous beep: Power supply, system board, RAM or keyboard problem Repeating short beeps: Power supply, system board or keyboard problem 1 long, 1 short beep: System board problem 1 long, 2 short beeps: Display adapter problem (MDA, CGA) 1 long, 3 short beeps
The actual key depends on specific hardware. The settings key is most often Delete (Acer, ASRock, Asus PC, ECS, Gigabyte, MSI, Zotac) and F2 (Asus motherboard, Dell, Lenovo laptop, Origin PC, Samsung, Toshiba), but it can also be F1 (Lenovo desktop) and F10 . [50] Features present in the BIOS setup utility typically include:
DFI (industrial motherboards), stopped producing LanParty motherboards in 2009; ECS (Elitegroup Computer Systems) EPoX (partially defunct) First International Computer; Foxconn; Fujitsu [1] Gumstix; Intel (NUC and server motherboards) Lanner Inc (industrial motherboards) Leadtek; Lite-On; NZXT; Pegatron; PNY Technologies; Powercolor; Sapphire ...
These motherboards often have a four pin straight header, with pin 2 missing, for connecting to an external 3.6v battery, such as the Tadiran TL-5242/W, when their soldered-on batteries run out. Ni–Cd batteries have a tendency to leak devastatingly after a period of disuse, damaging components and traces on the circuit board near the battery ...
When ASUS approached Intel to request a processor to test it, Intel itself had a problem with its own 486 motherboard. ASUS solved Intel's problem and it turned out that ASUS' motherboard worked correctly without the need for further modification. Since then, ASUS was receiving Intel engineering samples ahead of its competitors. [15] [16]
The purpose of overclocking is to increase the operating speed of a given component. [3] Normally, on modern systems, the target of overclocking is increasing the performance of a major chip or subsystem, such as the main processor or graphics controller, but other components, such as system memory or system buses (generally on the motherboard), are commonly involved.
