Windows 10 adjustment reducing my overclock performance
It might be several factors at play. Some motherboards list BCLK as 100.00, but checking cpu-z can show it fluctuating between 99.0 and 100.9, especially depending on the edition. I've tested different ASUS Rog vs MSI editions and found variations. Even minor changes in versions can lead to different outcomes.
Measuring clock speeds correctly isn't easy. You might rely on BIOS settings, but those are just numbers stored in CMOS memory, not the real clock rate. Frequency counting could work, though oscillators aren't perfect and clocks tend to drift significantly (I once saw a microcontroller lose minutes per hour in a simple test).
As long as the reported speed is close—typically within 5% or less—it should be acceptable.
No one enjoys the phrase 'Margin of Error,' yet we all have to consider it, particularly with today's fast processors, memory, component quality checks, and material standards. Those dealing with such issues would generally want 5% or less, but if it turns out to be 6%, the only solution is upgrading the hardware—like a new motherboard, CPU, or GPU.
Sometimes 'Good Enough' simply means accepting what is acceptable.
