There is no ac and dc option avaliable on x299 bios. Someone please help.....

Those options are not applicable to X299. They are designed to bring the voltage down closer to the user requested voltage as Intel's programmed VID will attempt to override what is being set, which is nessessary means on Intel's mainstream platforms. On X299 the voltage requested in adaptive mode will be close enough to what is being set by the user in the Additional Turbo Voltage field. That is unless the voltage being set is lower than the stock VID for a given ratio, which is not possible without use of the offset function.
It may be possible to reduce VCCIN to around 1.85v depending on the CPU to help reduce temps. However, if planning on running AVX workloads in tandem with overclocking the best answer in terms of tangable benefit would be to delid the CPU. Understandably if you're not comfortable invalidating your warranty then this isn't the solution for you.
Floating point tests such as AIDA's routine will push the CPU hard, you're asking a lot of the CPU. In fact I wouldn't recommend running this and stick to real world stability testing that mimics your workload more closely. I don't believe anyone in the tech media has provided any testing or oscilloscope shots with these CPU, but I'd imagine the current being pulled in those tests is quite eye opening.
