The GPU Boost Clock and available offset merely sets the maximum target frequency. The actual frequency under load is controlled by GPU Boost and will scale based on voltage, power, and thermal conditions. If wanting to lower the maximum obtainable boost clock, the GPU Clock offset slider will allow you to do so, albeit at the cost of performance.
Coil whine is related to both frequency and current and is often the result of a combination of certain hardware (graphics cards and PSUs) and is more prevalent at high current workloads, so will vary from system to system
