Speedshift option

Hello

Some people had talked about this option, but I can't find the posts anymore

I tested by activating it, and in idle, I have 700mhz for the CPU (indicated by several monitoring and the Task Manager)
I don't think the idle frequency can go down that low ?
What is this option for ?

Thanks
Sorry for my english 😄

Hi master tistou77, I'd notice Speedshift was setting to "AUTO" in CPU menu on BIOS since 3006 release.

I think it working with XMP profiles as well. it was auto overclock feature by CPU itself.

Interesting. I am with i7-7820X, rog strix x299-e gaming, bios 3006, win 10 x64 home 1903.
The only way I can get my i7-7820X to separate from 3.6 GHz is to disable the Intel(R) Speed Shift Technology option.

Also, if I want it to stick to the turbo 4.0 GHz, I need the Autonomus Core C-State disabled.

Any other setup that allows tapping into this?

Not long ago some mates at OC.NET discussed about speedshift, which is nothing more nothing less than an enhanced speedstep. Basically, it allows the cpu to increase speed faster.

Now that I was downgrading BIOS, first from 3006 to 2002, and then to 1902, I see the difference.

Under 2002 and 1902 BIOSes, my CPU has a healthy turbo boost behavior, it shifts from 3.6 to 4.5 GHz.
Under 3006 BIOS, it is stuck at 3.6 when it shouldn't be.

So, the 3006 got me to disable speedshift and the autonomous c states in order to separate the CPU from 3.6 GHz. On 2002 and 1902 I am happy with them being on auto. I am with i7-7820X and asus rog strix x299-e gaming.
