RAM Compatibility & Upgrades

A 3200 stick and a 3600 stick can share a system — they will both slow down to match. What else changes, and how to make it stable.

Yes — with one quirk called flex mode. How mixed capacities actually run, and how to arrange the sticks for the best result.

DDR5 brought on-module power management, higher speeds and fussier training. What AM5 and Intel 600/700/800-series owners need to know.

DDR4 ran for nearly a decade across Intel and AMD platforms, but not every DDR4 stick suits every DDR4 board. Here is what to verify.

Four things decide whether RAM works in your PC — generation, form factor, capacity limits and speed support. Check them in this order and you will never buy the wrong kit.
