How to Build a PC — RAM and Storage Compatibility Guide

The most common mistake new PC builders make is buying incompatible RAM or storage. Your motherboard chipset determines which RAM type (DDR4 vs DDR5), speeds, and maximum capacity are supported. Getting this wrong means returning parts and delays.

RAM Compatibility Checklist

1. Check RAM type — DDR4 and DDR5 are NOT interchangeable. 2. Verify maximum supported speed. 3. Check number of DIMM slots (2 or 4). 4. Note maximum capacity per slot. 5. Always buy a matched kit for dual-channel performance.

Mid (~£150)32GB DDR5-60001TB NVMe Gen4

Storage Planning

Modern motherboards have 2-4 M.2 slots. Plan your layout: one fast Gen 4 NVMe for OS and games, optionally a larger drive for media. Check whether M.2 slots share bandwidth with SATA ports.

Frequently Asked Questions

Do I need RAM from the QVL?

Not strictly — most standard RAM works. The QVL guarantees compatibility at rated speeds.

Can I mix RAM brands?

Possible but not recommended. Buy a matched kit for best results.
