Hello. Undervolt in custom mode seems to have no effect. CB scores/temps/watts wont change. Have tried all different combinations of BIOS settings. XTU and throttlestop show locked status for UV. XTU has “Undervolt Protection - No” in system information tab. VBS, Core Isolation and UV protection all off so UV should be enabled.

XTU shows “Overclocking is not currently enabled on this system. Check you BIOS settings for overclocking features. The platform fully supports overclocking for Processor Graphics, Processor Core & Processor cache.”

FYI. Synapse used 9% cpu and had impact on FPS in CPU heavy titles. Reinstall fixed it and CPU usage went under 1%.

I'm using the latest BIOS 2.0. For nornalize termals i tried reducing power consumption in RAZER Synapse by custom mode, but it didn't work, and I didn't notice any effects. Working only disable turbo boost from bios, but this is not enough.
