Adaptive Mode and Cascade Lake-X (X299)

[tistou]

Hello

Adaptive Mode (Vcore) on X299 motherboards does not work with Cascade Lake-X, is it a problem related to the CPU itself ?

Thanks

Hello

Thanks for your reply

I wanted to exchange my Skylake-X for a Cascade Lake-X and it seems that all Cascade Lake-X would be "affected" by this problem (with all motherboards)

Adaptive mode will work if the VID table cooperates. If the CPU is stable at a vcore lower than the VID, then adaptive is a problem

I have no problem with my Skylake-X, Adaptive Mode and a Vcore lower than the VID

Problem reported on some forums : https://www.overclock.net/forum/5-intel-cpus/1737048-intel-core-i9-10980xe-5-ghz-18-cores-124.html

Thanks

PS: sorry for my english

Hello tistou,

Thank you for your response.

We would like to mention that there is not a known performance issue reported on Intel® Core™ X-series Processors.

Modifying settings such as VCC, VID, and others to alter voltage or frequency of a processor can produce unpredictable results or system instabilities (overclocking or underclocking). This may also cause your system to work out of specifications.

What we can recommend is that you contact your motherboard manufacturer to obtain more information and step-by-step instructions to modify these settings in BIOS, and how they may impact the performance of your computer.

Also, you may purchase the Performance Tuning Protection Plan to cover processor failures caused by operating the processor outside of Intel’s published specifications.

Hello

If we use a fixed Vcore (VID), no problem

And leave the Vcore in AUTO, it's too high a tension

Motherboard manufacturers can't do anything, the problem comes from the behavior of the VID (too high by default)

Thanks for your help, I will probably keep my Skylake-X
