How to Choose DDR4 RAM
Three things decide a DDR4 purchase: how much you need, how fast it runs, and whether your board supports it. Buy as a matched kit (not single sticks added over time), aim for dual-channel, and check your motherboard's supported speeds. The guide below covers each decision.
DDR4 only works in DDR4 slots — it is not cross-compatible with DDR5, which uses a different slot and different boards. DDR4 is the standard for AMD AM4 and older Intel platforms. Check your motherboard model or look at the RAM already installed before buying, since a DDR5 board cannot take DDR4 and vice versa.
8GB is enough for light use and older games but is tight today. 16GB (2x8GB) is the comfortable gaming baseline and the most common choice. 32GB suits heavy multitasking, streaming while you play, and content creation like video editing or running virtual machines. Going beyond 32GB rarely helps general gaming.
For DDR4, a 3200MHz to 3600MHz kit is the value sweet spot — fast enough to matter, without paying a premium for diminishing returns. AMD Ryzen systems in particular benefit from well-matched RAM speed. Check your motherboard's supported speeds, because the board and CPU set the ceiling for what will run stably.
CAS latency is how many cycles the RAM waits before it can act — lower is better at the same speed. But latency and speed work together, so a faster kit with a slightly higher CL can still feel quicker than a slow, low-CL one. For most buyers, pick a sensible speed first, then choose the lower CL within that bracket.
Yes — out of the box, RAM often runs at a slower default speed, not its rated one. XMP (Extreme Memory Profile) is a one-click BIOS setting that applies the kit's advertised speed, timings and voltage. Enable it after installing, then confirm the speed with a tool like CPU-Z so you're actually getting what you paid for.
