The system includes unsupported memory. b. Memory is not installed or is not detected. c. Incompatible memory was installed. d. New and old memory have been mixed.

b. Memory is not installed or is not detected.

After installing a new RAM module, you boot your 64-bit system, but the display remains blank. What is the MOST likely cause of this issue? a. You have installed a 32-bit memory module. b. You have installed a non-parity RAM on an ECC system. c. The POST failed to recognize the new memory. d. The Registry is configured to write to faulty sections of RAM.

b. You have installed a non-parity RAM on an ECC system.

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 correct this issue? a. Install a 64-bit version of the operating system. b. Update the memory controller driver in Device Manager. c. Disable the AGP aperture in the BIOS. d. Flash the BIOS.

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

Which of the following are the MOST likely signs that your computer might need more memory? (Select two.) a. Your hard drive is constantly operating as you work. b. Your hard drive light on the system case is on for long periods of time. c. Your system boots, but the memory count is incorrect. d. You system boots, but the display remains blank. e. You receive an exception error when running a software program.

a. Your hard drive is constantly operating as you work. b. Your hard drive light on the system case is on for long periods of time.

You are attempting to boot a new system. The boot fails, and the system sounds a beep code. Which of the following describes the MOST likely cause of this error? a. Either a card/memory module is not seated properly or the system includes unsupported memory. b. Either no memory is installed or the memory was not detected. c. The POST failed to recognize all of the memory. d. The new memory is not compatible and was not installed and configured properly.

b. Either no memory is installed or the memory was not detected.

Which type of software-generated problems can indicate that a software bug is causing a memory error? (Select three.) a. Parity interrupt b. General-protection fault c. Incorrect memory count d. Exception error e. Registry error f. Page fault

b. General-protection fault d. Exception error f. Page fault

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 to resolve the issue? a. Add continuity modules to unused memory slots. b. Change the CAS latency to a higher setting. c. Replace the memory with dual-channel capable memory. d. Move the modules to the correct motherboard slots.

d. Move the modules to the correct motherboard slots.

Which of the following are critical times when memory problems manifest themselves? (Select two.) a. After cleaning the dust from inside your computer b. After you reconfigure the BIOS/UEFI c. After installing new drivers on your computer d. On the first boot of a new computer e. After you remove or install hardware

d. On the first boot of a new computer e. After you remove or install hardware

After installing two memory modules, you power on the system to check for errors. You find that the BIOS program recognizes only one of the memory modules. Which of the following is BEST to try first when troubleshooting this issue? a. Scan for new devices in Device Manager and enable any disabled memory modules. b. Return both modules for a replacement. c. Change the memory timings in the BIOS to a slower (higher) setting. d. Reboot the computer and run memory diagnostic tests. e. Make sure that both modules are seated properly in their slots.

e. Make sure that both modules are seated properly in their slots.
