| RAM latency (lower is better) | 80.3 ns | 83 ns |
| Rated speed | 6,400 MT/s | 3,200 MT/s |
| Runs at (seen, avg) | 6,400 MT/s | 3,200 MT/s |
| Capacity | 64 GB | 32 GB |
What the numbers mean
The RAM score is the kit's measured performance in the rigs it sat in — single-thread bandwidth and latency beyond L3. Platform, BIOS settings and whether XMP/EXPO was on all affect it. GAMING is the whole rig's score. We show both and never mix them.
All numbers come from our benchmark suite, the same test on every PC, written in Rust with no middleware. The methodology is open at https://whatfps.com/metodik
