PC hardware upgrade planning: When planning an upgrade for a specific motherboard, which key information must you identify first to ensure compatibility of CPU, memory, and expansion options?

Introduction / Context:
Selecting parts that truly fit a given PC depends on the exact motherboard you are targeting. Chipset, socket type, BIOS support, memory standards, and I/O headers all hinge on the board’s precise identity. Knowing only the RAM or storage tells you little about CPU sockets or firmware support, so the first step is always to identify the motherboard’s make and model.

Given Data / Assumptions:

• You plan to upgrade CPU, RAM, or storage on an existing PC.
• Compatibility depends on socket, chipset, form factor, memory standard, and BIOS.
• The question asks what you must know first for a particular motherboard.

Concept / Approach:

Motherboard identity (brand and model) uniquely determines chipset, CPU socket, supported RAM type and speed, M.2/SATA layouts, and maximum capacities. From the board’s support page you can read CPU QVL lists, RAM QVL lists, BIOS updates, and slot bandwidth details. Without this, you risk purchasing parts that do not work or that operate at degraded performance.

Step-by-Step Solution:

Verification / Alternative check:

Cross-check with third-party lists and forums, but rely on official support pages for final confirmation. If in doubt, test with known-good components before purchase.

Why Other Options Are Wrong:

• Memory / DIMM: helpful, but RAM type depends on the board’s model and chipset.
• Hard drive: storage is broadly compatible; not the primary determinant.
• None of the above: incorrect because make & model is essential.

Common Pitfalls:

Assuming any CPU fits any LGA/AM socket revision; ignoring BIOS microcode; mixing DDR generations; overlooking power delivery limits.

Final Answer:

make & model
