Memory
DDR4 or DDR5 starts with your exact motherboard
Choose the memory generation supported by the exact motherboard, and compare a platform change without treating DDR4 and DDR5 as interchangeable.

Memory
Plan memory capacity without filling every slot
Calculate total memory and occupied slots, distinguish module types and plan a complete validated kit without assuming that spare slots guarantee an upgrade.

Memory
What a memory QVL can and cannot tell you
Read a memory qualified-vendor list against the full kit code, installed-module count and platform conditions without mistaking a near match for validation.

Graphics
Measure graphics-card clearance in three dimensions
Compare exact card dimensions with the configured case, including radiator space, occupied slots and cable access. Includes a real MSI dimension example.

Graphics
Check graphics outputs against the actual monitors
Match each monitor with a documented graphics output, cable and display mode. Count connectors separately from the maximum simultaneous displays.

Graphics
Does the processor actually provide integrated graphics?
Check the exact processor graphics specification before relying on motherboard display outputs. Includes the i5-12400 and i5-12400F distinction.

Storage
M.2 size does not tell you the whole interface story
Read M.2 length codes, distinguish mSATA from M.2 and match the drive interface to the specific motherboard socket.

Storage
Choose SSD capacity with working space in reserve
Build a storage budget from your own files, working space and growth assumptions, with consistent capacity units.

Storage
Read the storage lane-sharing notes before adding drives
Map each planned drive to a documented socket and check the sharing conditions before committing to an expansion plan.

Fit & power
A PSU wattage label is only one part of the check
Check the exact PSU model, component requirements and compatible cables instead of selecting a power supply by wattage alone.
