3.8.8 Memory Installation

You have a computer that has four DDR2 memory slots. Currently there are two 512 MB memory modules installed. You check the motherboard documentation and find that the system has a 4GB memory limitation. You want to add as much memory as possible without replacing the existing modules. which of the following is the maximum total amount of RAM that can be installed in this system?

3 GB

You want to build a new system that supports 6GB of memory. Which of the following will be the most important consideration when building the computer?

64-bit processor

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 300 MHz.

What type of RAM might slow system performance because it holds memory addresses or data to improve stability on systems with more than 1 GB of RAM before it is transferred to the memory controller/

Buffered

A new computer is being purchased for Peter, the new administrative assistant. Peter primarily uses word processing, spreadsheets, presentation software, and a web browser to complete his job assignments

Buffered memory is more expensive and slower than unbuffered memory

You work as the IT administrator for a small corporate network. Sam, an employee in the support department, wants to run a virtual machine on his computer to troubleshoot customer issues from, and he needs a very stable dcomputer from which to work. You need to decided whether to install buffered or non buffered RAM in his computer. Which of the following BEST describes the reason to choose buffered instead of unbuffered memory for this new computer?

Buffered memory reduces the load on the memory controller and allows the system to be more stable.

With a memory module read request, there is a delay between the time of the data request and the time the data is available for output from the memory module. What is this delay called?

CAS Latency

You have an existing system that has a single DDR3 memory module installed. You would like to add more memory to 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?

Check the motherboard documentation to find which modules are supported. Purchase additional modules that are the same as what is currently installed.

You want to upgrade all memory in your system with the fastest memory available. Which of the following should you choose?

Choose the type of memory that is supported by your motherboard.

You are in a carpeted office lighted by fluorescent bulbs. You are preparing to add memory modules to a user's computer. The user has already unpacked the memory and stacked them on top of an old, unused CRT monitor. What is the greatest threat in this environment that could damage these memory modules?

Electrostatic discharge (ESD)

Paul has just joined your company, and you are in the process of purchasing a laptop computer for his use. Paul will work as a sales rep in the sales department You ahve heard that some types of RAM are better than others. which of the following type of RAM would BEST meet the needs of Paul's new computer?

Non-ECC memory, as it is less expensive, and partity is not required

Which of the following statements is true regarding single- and double- sided memory?

Single sided memory uses half of the memory modules as double- sided memory of the same capacity.

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

The memory controller must support dual-channels. Bandwidth is increased by 5-15%.

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

move the tabs holding the ram out of the way; pull straight up to remove the RAM.
