- A
Install the modules in slots 1, 2, 3, and 4 in any order.
Why wrong: While the system will likely work, the order matters for dual-channel operation; but the most important consideration is that all modules are matched.
- B
Ensure all modules are from the same manufacturer and have the same speed and timings.
Using identical modules from a matched set ensures compatibility and prevents issues like timing mismatches that can cause crashes or failure to boot.
- C
Install the modules only in the first two slots to leave room for future upgrades.
Why wrong: The user needs 64 GB now, so all four slots should be used. Leaving slots empty would not meet the requirement.
- D
Set the RAM voltage to the maximum supported by the motherboard.
Why wrong: Setting voltage too high can damage the modules. The correct voltage is specified by the manufacturer, and modern RAM typically uses 1.2V for DDR4.
Installing Four RAM Sticks: Matching Specifications
This 220-1201 practice question tests your understanding of ram. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A technician is configuring a workstation for a video editing application that requires 64 GB of RAM. The motherboard has four slots and supports up to 128 GB. The technician has four 16 GB DDR4-3200 modules. What is the most important consideration when installing these modules?
Quick Answer
The answer is that ensuring all four RAM sticks are from the same manufacturer with identical speed, timings, and voltage is the most important consideration. This is because even if modules share the same rated speed, subtle differences in internal timings or voltage tolerances between different batches or brands can cause system instability, random crashes, or failure to boot when populating all four slots. On the CompTIA A+ Core 1 220-1201 exam, this concept tests your understanding of memory compatibility and the risks of mixing modules, often appearing as a trap where a candidate might focus solely on slot order or total capacity. A common memory tip is to think of RAM sticks like a matched set of tires—mixing brands or wear levels compromises performance and safety, so always verify the model number and revision on the labels.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Ensure all modules are from the same manufacturer and have the same speed and timings.
When installing four identical RAM modules, the key consideration is ensuring they are all from the same matched set or have identical specifications (speed, timings, voltage) to maintain stability and performance. Mixing modules from different manufacturers or batches can cause instability even if they have the same rated speed. Additionally, the technician should install them in the correct slots for dual-channel operation, but the primary concern is compatibility.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 220-1201 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
