question
A motherboard uses dual channeling, but you have four DIMMs available that differ in size. The motherboard supports all four sizes. Can you install these DIMMs on the board? Will dual channeling be enabled?
answer
Yes, the DIMMs will work on the motherboard, but dual-channeling will not be enabled

answer
PC3200
question
You need to find out how much RAM is installed in a system. What command do you execute to launch the System Information utility
answer
MSINFO32.exe
question
Although ECC memory costs more than non-ECC memory, why would you choose to use it? Which type of computer typically requires ECC memory
answer
ECC is more reliable, Servers
question
You need to upgrade memory in a system but you don't have the motherboard documentation available. You open the case and notice that the board has four DIMM slots; three slots are colored yellow and one slot is black. What type of DIMM does the board likely use? How can you be sure?
answer
It uses DDR3 because the 3 colors show it supports triple channeling. Check notches to know for sure
question
If your motherboard supports DIMM memory, will RIMM memory still work on the board
answer
No
question
If your motherboard supports ECC DDR3 memory, can you substitute non-ECC DDR3 memory
answer
Yes, ECC will just be disabled in BIOS
question
You have just upgraded memory on a computer from 1 GB to 2 GB by adding on DIMM. When you first turn on the PC, the memory count shows only 1 GB. Which of the following is most likely the source of the problem? What can you do to fix it?
answer
The memory is not seated properly
question
Your motherboard supports dual channeling and you currently have two slots used in Channel A on the board; each module holds 1 GB. You want to install an additional 1 GB of RAM. Will your system run faster if you install two 512-MB DIMMs or one 1-GB DIMM? Explain your answer?
answer
Installing 2 512-MB will make dual channeling active and will end up being faster if done this way
question
What is the fastest DDR3 DIMM sold today
answer
4.4 GHz
question

answer
8GB
question
What is the largest size fully buffered ECC 240-pin DDR2 DIMM sold today
answer
8GB
question
What is the lowest price for an 8-GB 240-pin ECC DDR3 DIMM
answer
$70
question
When installing a processor, always follow the directions given in the motherboard user guide and be careful to protect the board and processor against ESD. Current Intel sockets LGA1150, LGA1155, LGA1366, and LGA775
answer
use a socket lever and socket load plate. When opening these sockets, lift the socket lever and then the socket load plate, install the processor, and then close the socket. Many AMD sockets have a socket lever, but not a socket load plate.
question
DIMMs can work together in dual channels, triple channels, and quad channels so that the memory controller can access more than one DIMM at a time to improve performance. In a channel, all DIMMs must match in size, speed, and features.
answer
DDR3 DIMMs can use dual, triple, or quad channeling, but DDR and DDR2 DIMMs can only use dual channels. DDR4 DIMMs can use dual or quad channels.
question
How to Upgrade Memory When upgrading memory, use the type, size, and speed the motherboard supports and match new modules to those already installed.
answer
Features to match include DDR4, DDR3, DDR2, DDR, size in MB or GB, speed (MHz or PC rating), buffered, registered, unbuffered, single-sided, double-sided, CL rating, tin or gold connectors, support for dual, triple, or quad channeling, ECC, and non-ECC. Using memory made by the same manufacturer is recommended.
