Performance and where it ranks
Two different questions, side by side. Performance compares what the hardware can do; Value compares what that capability costs at today’s price. A product can rank high on one and low on the other — that gap is the point.

Balanced has no letter: it is a weighting preset, not a capability rubric. A grade answers “how well does this handle that job?” — price is never part of it. Relative Value puts the current market price back in.

What to check in your build
DDR5
The board must take DDR5 — DDR generations are not interchangeable
288-pin DIMM
Desktop boards take full-size DIMMs; laptops and mini PCs take SO-DIMMs.
2 free slots
A kit is tested as a set; filling fewer slots than modules is not possible.
XMP/EXPO support for 6400 MT/s
6400 MT/s is a profile speed — the board and CPU memory controller have to support it, and it is off until you enable it in BIOS

FAQ
Why does Relative Value change when I choose another scenario?
Each scenario changes the weights applied to capability, price and the other published factors. The hardware facts stay fixed, but the value question changes, so its score and rank can change too.
Why can Amazon appear without a tracked price?
Amazon is shown as a discovery link when we do not have a permitted verified price snapshot. It is excluded from price comparisons, rankings and Relative Value until a compliant tracked price exists.
