• Printers

• Laptop computers

You have an existing system that has a single DDR3 memory module installed. You would like to add more memory to the three remaining empty memory slots.

Which of the following steps should MOST likely be taken to make sure you get the right memory for the system? (Select TWO).

• Update the BIOS and then purchase the newest memory modules available.

• Purchase the fastest modules possible.

• Purchase additional modules that are the same as what is currently installed.

• Check the motherboard documentation to find which modules are supported.

Which of the following are true regarding a dual-channel memory bandwidth configuration? (Select TWO)

• Only DDR2 memory is supported.

• The memory controller must support dual-channels.

• Bandwidth is increased by 5-15%

• Bandwidth is doubled.

You have a computer with a Pentium 4 CPU and two PC-2400 DDR modules. The motherboard has room for two additional memory modules, and you'd like to install two PC-4000 modules.

Which of the following statements is true?

• All memory will operate at 500 MHz.

• You cannot mix memory modules with different ratings.

• Half of the memory will operate at 300 MHz, and the other half at 500 MHz.

• All memory will operate at 300 MHz.

Which of the following is the most common method for removing RAM from a motherboard?

• Remove the screw from the one side; pull straight up to remove the RAM.

• Move the tabs holding the RAM out of the way; pull straight up to remove the RAM.

• Pull the RAM module up from one corner and then twist to release the other corner.

• Tip the RAM module at a 45-degree angle while pulling on it.

You are in the process of configuring a new computer. The motherboard has four memory slots and supports dual-channel memory. You install two memory modules. When you boot the computer, the BIOS recognizes both modules, but the memory is not configured to run in dual- channel mode. What should you do?

• Add continuity modules to unused memory slots.

• Replace the memory with dual-channel capable memory.

• Move the modules to the correct motherboard slots.

• Change the CAS latency to a higher setting.

You have installed a new computer with a quad-core 64-bit processor, 6 GB of memory, and a PCIe video card with 512 MB of memory. After installing the operating system, you see less than 4 GB of memory showing as available in Windows.

Which of the following actions would MOST likely rectify this issue?

• Disable the AGP aperture in the BIOS.

• Install a 64-bit version of the operating system.

• Flash the BIOS.

• Update the memory controller driver in Device Manager.

Which of the following is an error detection technique that can detect errors with only one bit?

• EDO

• Parity

• Non-parity

• ECC
