Speed Shift / EIST / power plan questions

[Elric82]

Hi,
I run my OC with fixed vcore, LLC Turbo on my 9900k
My power plan is "normal"
Right now Speed Shift / EIST are enabled
Is there any loss of stability / performance if those are enabled?
Should I enable all of them ? One of them? Neither?
I would like to know what is the "ration" beetween performance and cooling by using or not those different setttings and also If I should use max performance on windows power plan.
Thanks

I was told that having a fixed vcore, those were useless but maybe it was misleading?

No I meant that i was told that EIST ans Speed Shift are useless since i run a static vcore. But apparently that was wrong

But it's better to disable those when stabilizing oc right?

Could not manage yet to get a dynamic vcore stable i need to try again but it's time consuming
