Notes from the workshop / 9 September 2026

Why every build gets a matched memory kit, never mixed sticks

The two facts a plain "32 GB" doesn't tell you: whether the sticks are a matched pair, and whether the timings are tuned to the platform. What we write instead, and why it matters on Ryzen specifically.

Most listings show one number: "32 GB." That tells you the capacity and nothing else — not whether it's one stick or two, not whether the two are a matched pair, not whether they're running at a speed the platform can actually use.

What we write instead

Kit, capacity, speed and timings, on one line: "32 GB DDR5-6000 CL30, matched 2×16 GB." Two sticks from one kit, always. Never a single module thrown in to hit the number, never two sticks pulled from different batches.

Why it matters on Ryzen specifically

On AM5, memory speed and timing aren't a spec-sheet decoration. They show up in real, measurable performance. A build that lists "32GB" and stops there could be running well under what the platform is capable of, and there's no way to tell from that listing alone.

  • Dual-channel needs a matched pair. Mixed sticks either fall back to single-channel or won't run at their rated speed at all.
  • The kit and its timings go on your specification next to the capacity, so it's checkable against what actually ships.
  • A 96 GB build gets the same rule as a 32 GB one: matched kit, tuned to the CPU, no exceptions for the bigger number.

If a specification lists a capacity and nothing else, ask what kit it is. Often there isn't one.

    The one part almost nobody asks about, and the one most likely to take the rest of the machine with it. What we write on the specification, and why.

  2. Why storage is chosen by endurance, not capacity

    Capacity is the number that sells a drive. Endurance is the number that decides whether it's still healthy in year four. What TBW means, and why we check it before a drive goes in a build.
