BIOS indicates 4 GHz, while CPU-z reports 3.6 GHz during the stress test.

Not sure when this started happening but I have been running an i7 6800k at 4.0 GHz for a while and today I noticed that it's only running at 3.6 GHz according to CPU-z, AIDA, HWMonitor and Windows itself. The behavior is the same when running the AIDA stress test. Even if I set the power plan to always run at max speed it never goes above 3.6 GHz - it just stays at 3.6 GHz, never rises or falls.
But here's the kicker: the BIOS it says it's running at 4.0 GHz.
Any ideas on what could be going on?
Am I running at 4 GHz or not?
Thanks,

Update - the BIOS adjustments aren't making a difference since I altered the multiplier to various numbers, and all system tools (CPU-z, AIDA, etc.) still show 3.6 GHz. Additionally, during the stress test, temperatures are significantly lower than expected if the processor were actually running at 4+ GHz. It's clear it isn't operating at 4.0 GHz in Windows. Anyone have an explanation?
Thanks, rgames
