Exercise $6\mathrm{.}3$ Configuring Memory on Paper

Objective: To be able to determine the correct amount and type of memory to install on a motherboard

Pars: Internet access or access to magazines or ads that show memory prices

Procedure: Refer to Figure $6\mathrm{.}24$ to answer the questions. The motherboard supports the following memory configurations:

$>1GB,2GB,4GB$ unbuffered and non$-$ECC DDR$3$ DIMMs can be used in the DIMM slots $(1,2,3,$ and $4)$ for a total of $32$ GB max using DDR$31066/1333$ MHz modules.

$$ Recommended memory configurations are modules in DIMMs $1$ and $3$ or modules in DIMMs $1,2,3,$ and $4.$

$>$ Single$-$ and dual$-$channel modes are supported.

$>$ You may install different sizes in Channel A and $B.$ The dual$-$channel configuration will be the total size of the lowest$-$sized channel. Any excess memory will operate in singlechannel mode.

$>1\mathrm{.}05V$ DIMMs ane recommended.

$>$ Lise the samre CAS latency and oblain thom the stmte verdor, if possible.

$>$ The defaule memory operation frequency is dependem on SPD$.$

What memory features, if any, are used? $($Choose all that apply.$)$

$[$ parity I non$-$parity $($ ECC I registered I unbuffered I SPD $]$

The customer wants $4GB$ of RAM. What memory modules are needed? $($What capacities and how many of each capacity are required?$)q,$

What memory slots will be used to install the memory suggested in Question $2?$

Using the intemet, a computer parts magazine, or a list of memory modules provided by the instructor, determine the exact part numbers and quantities of memory modules that you would buy. List them, along with the location where you oblained this information. $q,$

In what type of systems would ECC modules most likely be required and used?

$[$ student desktop I smartphones I tablets I servers I laptops $]$

What is the purpose of ECC modules?

Whai is the purpose of SPD$?$
