5 Things to Know About Mixing DDR5 RAM Sticks

Only buy the exact same model Mixing different brands or even the same brand with a different revision can cause instability or force slower speeds.

Match the part number, timings, and voltage If you find an identical 8GB stick with the same specs, your i5-12400 will run them in dual-channel fine.

Avoid generic replacements Guessing or buying a generic “DDR5-4800” from another brand risks losing performance or random crashes.

A matched kit is safer A 2x8GB kit guarantees factory-matched sticks and avoids compatibility headaches.

Sell your old stick to offset cost You can sell your single stick for around $20 and buy a matched kit instead of gambling on mixing.
