Idle clocks drop because of power-saving (Intel SpeedStep, AMD Cool’n’Quiet, modern CPPC). Under load, you should see the CPU approach its advertised or PBO-boosted speeds. If it never rises, check power plan, thermal throttling, or laptop “quiet mode”.

Press F9 to switch clock computation methods if you are comparing behavior across versions.

DDR effective data rate is roughly 2× the DRAM frequency shown (DDR double-pumps). A 1800 MHz DRAM clock corresponds to DDR4-3600 effective. If the number looks “half” of what you expect, verify whether you are reading the right field and whether XMP/EXPO is enabled in BIOS.

Bandwidth can be computed from conservative SPD timing fields; kits rated at higher voltage via XMP may appear lower at JEDEC defaults. Always compare the SPD profile list with what is selected in BIOS.

Manufacturer and model help you find the right chipset drivers. BIOS version matters for microcode updates and AGESA revisions. PCIe link width confirms your GPU is running at x16 (or x8 if bifurcated).

Shows GPU name, process, and clocks. Useful for hybrid laptop setups (integrated + discrete) to confirm which GPU is active. For detailed monitoring, use GPU-Z or vendor tools.

Cache sizes, associativity, and line sizes. Helps developers and power users understand cache topology. Rarely needed for forum screenshots unless the question is about cache hierarchy or optimization.
