Chapter 3 - All About Motherboards (Review Questions)

The most popular motherboard form factors are ATX, microATX (a smaller version of ATX), and Mini-ITX (a smaller version of microATX).

Both the memory controller and graphics controller are contained within all Sandy Bridge processors.

Intel Socket B, also known as LGA1366, has 1366 pins in the socket touch.

LGA1155 works with DDR3 memory and was designed to replace the LGA1156 socket.

Sandy Bridge uses only one chipset housing which houses the Platform Controller Hub.

The AMD socket AM3 (AMD3) has 941 holes for pins (PGA).

The North Bridge is where part of a Nehalem chipset connects directly to the processor. (ref. Figure 3-12)

The throughput of PCI Express Version 3 has a bandwidth up to 32 GB/sec for 16 lanes whereas the PCI Express Version 3 has a bandwidth up to 16 GB/sec for 16 lanes.

The maximum wattage that a PCIe Version 2.0 expansion card can draw is 300 W.

The 6-pin PCIe connector from the power supply provides an additional 75 W.

The 8-pin PCIe power connector provides 150 W.

The PCI riser card installs in the slot and provides another slot at a right angle. When you install an expansion card in this riser card slot, the card sits parallel to the motherboard, taking up less space and can be used to solve the problem.

The TPM chip is the chip on the motherboard does Windows BitLocker Encryption use to secure the hard drive.

In the BIOS Setup you can view information about the BIOS version, processor model and speed, memory speed, total memory, and the amount of memory in each memory slot.

Two reasons you might decide to flash BIOS are: -The system hangs at odd times or during the boot. -Some motherboard functions have stopped working or are giving problems. For example, the onboard video port is not working.

Out of the four methods listed in the textbook, express BIOS update was the easiest way to obtain the latest software to upgrade BIOS.

If both passwords are forgotten, you cannot use the computer. However, jumpers can be set to clear both passwords.

A small amount of memory stored on the motherboard that retains the data even when the computer is turned off because it is charged by a nearby lithium coin-cell battery

You access the BIOS setup program by pressing a key or combination of keys during the boot process. For most motherboards, you press F2 or Del during the boot. For a few older motherboards, you press Ctrl+Alt+Esc. See the motherboard documentation to know for sure which keys to press.

Windows 7 does not support a secure boot in UEFI. Windows 8 and Linux Ubuntu version 14 does.

The GUID Partition Table (GPT) method is newer, allows for any size hard drive, and, for Windows, can have up to 128 partitions on the drive. GPT is required for drives larger than 2 TB or for systems that boot using UEFI firmware.

You don't have to replace an entire motherboard if one port fails. For example, if the network port fails, use BIOS setup to disable the port. Then use an expansion card for the port instead.

PCIe Version 2.0 has an additional 75 W power that come from a second auxiliary connector on the motherboard. This second connector can be a 6-pin PCIe connector, a Molex-style connector, or a SATA-style connector.

The purpose of installing standoffs or spacers between the motherboard and the case is so that the components on the back of the motherboard do not touch the case.

No, because these are the wires for the switches, lights, and ports on the front or top of the computer. (ref. Chapter 2, Steps to Put a Computer Back Together)
