220-1101 Hardware Practice Question
A technician is building a high-end workstation for 3D rendering. The chosen CPU uses an LGA 1200 socket and supports dual-channel memory. The technician needs a motherboard that supports the CPU, at least two PCIe x16 slots for dual graphics cards, and should allow memory overclocking for optimal performance. Which of the following motherboard chipsets is the most suitable for this task?
⚠ Common exam trap
Candidates often assume any ATX motherboard with multiple PCIe slots supports memory overclocking, but only Z-series chipsets (like Z490) provide that capability, while Q-series and H-series chipsets lock memory multipliers.
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
✓
ATX motherboard with Z490 chipset
The Z490 chipset is the only option that supports both dual-channel memory overclocking (via unlocked memory multipliers) and multiple PCIe x16 slots for dual graphics cards, while also being compatible with the LGA 1200 socket. This makes it ideal for a high-end 3D rendering workstation where CPU and memory performance are critical.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
ATX motherboard with Z490 chipset
Why this is correct
The Z490 chipset paired with an ATX board is the right choice for a high-end 3D rendering workstation because it explicitly permits CPU and memory overclocking — critical for squeezing shorter render times out of a K-series processor — and typically provides two full-length PCIe x16 slots that can run in x8/x8 mode, enabling dual GPU configurations for GPU-accelerated rendering. Additionally, ATX form factor leaves room for multiple NVMe drives, high-capacity RAM, and robust power delivery. With Z490 you also get flexible I/O, including Thunderbolt on select models, making it suitable for high-throughput asset ingestion and output.
- ✗
Micro-ATX motherboard with H410 chipset
Why it's wrong here
The micro-ATX H410 board is incompatible with a high-end 3D rendering PC because H410 is a budget chipset that offers only a single PCIe x16 slot, eliminating any possibility of running dual GPUs for parallel rendering. It also lacks CPU overclocking support and limits memory to slower speeds without XMP, which bottlenecks both CPU and GPU performance. While it works for a basic office PC, it cannot handle NVLink or multi-GPU workloads typical in 3D rendering.
When this WOULD be correct
This option would be correct for a budget office or home PC build where the CPU is a lower-power model (e.g., Core i3) and the user does not need overclocking, dual graphics, or high memory speeds. The H410 chipset is cost-effective for basic tasks.
- ✗
Mini-ITX motherboard with B460 chipset
Why it's wrong here
The Mini-ITX B460 board fails for this build due to having only one expansion slot — specifically one PCIe x16 slot — so it is physically impossible to install two graphics cards, and B460 does not support memory overclocking beyond JEDEC speeds. Even if a single powerful GPU were used, the small board usually has just two DIMM slots, capping total memory capacity, which is inadequate for large 3D scenes that demand 128GB or more. Its SFF layout also restricts airflow and cooling, which hurts sustained render workloads.
When this WOULD be correct
A technician building a compact, low-power home theater PC (HTPC) that requires a small form factor, basic graphics, and no overclocking would choose a Mini-ITX motherboard with B460 chipset.
- ✗
ATX motherboard with Q470 chipset
Why it's wrong here
The ATX Q470 chipset targets business and corporate desktops, not performance workstations; it lacks CPU overclocking and typically downplays enthusiast features like PCIe lane bifurcation. Although Q470 boards come in ATX, they often provide only one full-speed PCIe x16 slot, with the second slot electrically limited to x4, making dual-GPU rendering crippled and unreliable. Its support for Intel vPro and manageability features is useful for IT departments but irrelevant for a 3D render node, so it is the wrong choice despite its size.
When this WOULD be correct
This option would be correct for a business workstation requiring Intel vPro, AMT, and enhanced security features, where memory overclocking and dual graphics are not needed, and stability and manageability are prioritized.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The 220-1101 exam frequently reuses these exact scenarios with slightly different constraints.

✗Micro-ATX motherboard with H410 chipsetWrong answer — click to see why▾
Why this is wrong here
The H410 chipset does not support memory overclocking (XMP) and typically lacks support for dual PCIe x16 slots, making it unsuitable for a high-end 3D rendering workstation with dual graphics cards and overclocked memory.
★ When this WOULD be the correct answer
This option would be correct for a budget office or home PC build where the CPU is a lower-power model (e.g., Core i3) and the user does not need overclocking, dual graphics, or high memory speeds. The H410 chipset is cost-effective for basic tasks.
Why candidates choose this
Candidates may see 'Micro-ATX' and assume it is sufficient for a workstation, or they may not realize that H410 lacks overclocking support and PCIe lane configuration for dual GPUs, focusing only on socket compatibility.
✗Mini-ITX motherboard with B460 chipsetWrong answer — click to see why▾
Why this is wrong here
The B460 chipset does not support memory overclocking (XMP) and typically has only one PCIe x16 slot wired electrically for x16, limiting dual GPU performance.
★ When this WOULD be the correct answer
A technician building a compact, low-power home theater PC (HTPC) that requires a small form factor, basic graphics, and no overclocking would choose a Mini-ITX motherboard with B460 chipset.
Why candidates choose this
Candidates may confuse B460 as a 'gaming' chipset due to its common use in budget builds, overlooking its lack of overclocking support and limited PCIe lanes for multi-GPU setups.
✗ATX motherboard with Q470 chipsetWrong answer — click to see why▾
Why this is wrong here
The Q470 chipset does not support memory overclocking (XMP), which is required for optimal performance in 3D rendering. It also typically lacks support for dual PCIe x16 slots for dual graphics cards.
★ When this WOULD be the correct answer
This option would be correct for a business workstation requiring Intel vPro, AMT, and enhanced security features, where memory overclocking and dual graphics are not needed, and stability and manageability are prioritized.
Why candidates choose this
Candidates may see 'ATX' and 'Q470' and assume it's a high-end chipset, but Q470 is actually a business-oriented chipset that lacks overclocking and multi-GPU support, unlike the Z490.
